BIOS (UEFI) does not see the bootable USB flash drive.

Here is such a dialogue I recently had with one of my acquaintances, we, of course, eliminated the problem of invisibility, but the conversation was long

In general, most often this problem is encountered when reinstalling Windows, and sometimes it is far from easy to solve it. In fact, there are many reasons for invisibility, but I will highlight the most basic ones in this article. By going through them, I think you can easily configure and install a new Windows.

The main reasons why the BIOS does not see the bootable USB flash drive

1) Incorrectly recorded bootable USB flash drive with Windows

This is perhaps the most common reason. Many users create bootable flash drives in one scenario: they simply copy files from a Windows CD / DVD to a USB flash drive. At the same time, some users say that everything works.

Perhaps this is true, but it is not entirely correct. To create bootable flash drives, it is best to use special utilities (especially since there are quite a few of them!).

I recommend trying the following utilities: Ultra ISO, Rufus, WinSetupFromUSB, WintoFlash, Windows 7 USB dvd download tool (utility from Microsoft).

A complete list of utilities for creating bootable USB drives. you can see here

Example: how to properly write a bootable USB flash drive in Rufus

1) First step: insert the USB flash drive into the USB port of the computer. We copy all important data from it to the hard disk (if any). Then it can be formatted (optional).

2) Second action: the Rufus program must be run as administrator (for this it will be enough to right-click on the executable file “rufus.exe”, select it in the appeared context menu);

3) Now we go to the Rufus settings (the screen below is an explanation to it for each item):

  • column “Device”: select our USB flash drive for recording;
  • Under the number 2 in the screenshot, there is a button that sets an ISO image file with Windows OS, intended for you to write to a USB flash drive (just specify it);
  • column “Partition scheme”: “GPT for computers with UEFI” (if you have a new PC / laptop, more details about it here);
  • column “File system”: select FAT 32 (usually, it is installed by default);
  • The last button (“Start”). start recording process.

Before recording, Rufus, by the way, will warn you that all data on the flash drive will be deleted. If you didn’t manage to save something. save after formatting the flash drive. data recovery will not be so easy.

That, in fact, is all, a flash drive recorded in this way should work 100% and be visible, in almost any modern BIOS version (UEFI).

2) Boot priority is not set in BIOS (UEFI)

So that you can boot from the flash drive and start installing Windows. it is necessary to configure the BIOS / UEFI correctly (and there are always difficulties with this, especially for novice users).

First you need to enter the BIOS settings.

In order not to repeat myself, I give a link to my previous article, which describes in detail how to enter the BIOS, which buttons and from which manufacturers to press.

The BIOS has a boot priority (sometimes called a boot queue): for example, it first checks a floppy disk for boot records, if not, then the hard disk, then the CD drive, etc. As soon as boot records are found on some media, the computer will boot from it.

Our task: to change the boot priority so that first of all the computer checks the boot records on the USB flash drive, and then on the hard drive.

To do this, the BIOS / UEFI has a BOOT section. For example, the screenshot below illustrates the following download priority:

  • CD / DVD discs;
  • HDD.

Naturally, with this setting. no matter how much you insert a USB flash drive into the USB port. the computer will not see it!

By changing the boot priority to your own. that is, putting USB in the first place, instead of a CD / DVD drive, you can boot from a USB flash drive (do not forget to save the settings.F10 key. Or Exit: Save and Exit).

Boot section. boot setup (example of UEFI settings)

What else I want to note: various BIOS versions may differ in menus, sections, in general appearance.

The screenshot below shows the settings for the “Award Software Advanced BIOS Features”. in it, in order to boot from a USB flash drive, you need to opposite the item “First Boot Device” (note: the first boot device). put up a USB-HDD (this is a USB flash drive). Next, save the settings (F10 key).

In the BIOS, laptops usually always have a BOOT section. Having entered it, you also need to put the device in the first place: USB Storage Device, USB-HDD, USB device, etc. (depending on your laptop model, BIOS version).

3) Secure Boot is not disabled in BIOS (or wrong flash drive)

Secure Boot is a relatively new feature that is designed to prevent unwanted software from running when the computer is turned on. In all modern laptops and computers, this option is available (until about 2013, it was almost never met). Secure Boot support Windows 8, 8.1, 10.

  • Create a UEFI flash drive, thereby not having to disable Secure Boot in the BIOS. How to create such a bootable USB flash drive is described here;
  • Disable Secure Boot in BIOS and install Windows OS (by the way, for example, Windows 7 does not support this function at all).

To disable Secure Boot. you need to enter the BIOS and open the BOOT section (in most cases this is the case, but sometimes this function is contained in the “Advanced” section).

As a rule, in BOOT, you need to change the following (for example, a Dell laptop):

  • Boot List Option: change UEFI to Legacy;
  • Fast Boot: Change Enabled to Disabled (ie disable “fast” boot);
  • don’t forget to change the boot priority (see example screenshot below).

On newer computers and laptops, some of the USB ports are in the old “format”. USB 2.0, the other in the new. USB 3.0. When copying files to a USB flash drive. there is no big difference which USB to use (well, except for the data transfer speed).

But when installing Windows. the choice of USB port plays a key role! The thing is, Windows 7 does not support USB 3.0 installations! Those. by inserting a bootable USB flash drive into such a port. you will not be able to install Windows 7!

How to distinguish a USB 3.0 port from a USB 2.0 port

Everything is very simple. USB 3.0 are marked in blue (or blue): moreover, both plugs and ports are marked. Take a look at the two photos below. everything is clear on them.

Another case in point: USB 2.0 and USB3.0

Note: Windows 8, 10. can be installed using USB 3.0 (USB 3.1) ports.

Without going far from the USB ports, I would also like to dwell on the following point: does the USB port work at all? If you have an “old” Windows OS installed, and it still “somehow” works (and in most cases it does). try to boot the computer and check the port.

I recommend paying special attention to the USB ports located on the front panel of the system unit, on keyboards, adapters, etc.

Often, the reason lies precisely in this: for example, one friend of mine could not install Windows, because he connected a bootable USB flash drive to USB ports on the keyboard, and these ports began to work only after Windows was loaded.

Therefore, a simple advice: try connecting the flash drive to another USB port (preferably USB 2.0), on the back of the system unit.

6) “Brutal” collection with Windows

There is not much to comment on here. any assemblies can be the cause of anything (I, of course, exaggerate somewhat, but still.).

In general, I recommend using a licensed version of Windows OS. this way you will not only lose less time on debriefing with the installation of the OS, but also further, in the process of work, settings, etc.

7) “Old” PC, does not support booting from flash drives

If you have an old computer, then it is quite possible that it may not support the option of booting from USB flash drives at all (however, in this case, you will not be able to configure the BIOS. it simply will not have an item for selecting USB-Flash Drive ( i.e. it will be obvious)).

If you have an old PC and want to install from a USB stick, there are several ways:

  • update the BIOS version to a newer one that supports booting from a USB flash drive (If, of course, there is such an update on the website of your hardware manufacturer. Important! Updating the BIOS may cause the PC to malfunction!);
  • use a boot manager such as Plop Boot Manager. In this case, you first boot into this manager (by the way, you can burn it to a CD), and then select boot from a USB device in it and continue with the installation.

Perhaps the bootable USB flash drive is not visible not only when the computer boots, but in general: on any PC, and not in any Windows? You can learn more about this in this post.

USB drive for UEFI computer

If you buy a new computer or laptop now, it will definitely support UEFI BIOS. There are many benefits to using the new UEFI BIOS, so the bootable flash drive must be UEFI capable.

If you create a bootable USB drive for Windows 7, 8.1 using MediaCreationTool, the UEFI system will support it. And with the Windows USB / DVD Download Tool for Windows 7, this option will not work.

Let’s consider the option of creating an installation flash drive with support for UEFI systems for Windows 7. To do this, download the Rufus program at https://rufus.akeo.ie. Please insert the USB stick before starting the program. After launching the Rufus utility, select the Windows 7 image. You can do this by clicking on the DVD disc icon. The program window will look like this.

If all the points match, as shown in the figure, then feel free to press the Start button. after which the recording of files will begin.

After the files are written, you can use the flash drive to install Windows on a UEFI system. Rufus can also be used for systems with a regular BIOS. A notable feature of the Rufus program is the fast speed of writing the image to the drive.

After reading this material, you can create bootable USB drives for Windows and Linux-like operating systems. And you will not have such questions as: why is there no USB flash drive in the BIOS or why Windows does not support the UEFI system.

BIOS settings

Check if USB device support is enabled. How to do this depends on your motherboard model. After turning on the computer, the message “Press [key] to enter Setup” appears at the bottom of the screen. Click it to enter BIOS. And look for a menu that has “USB” in its name.

Award BIOS setup

To enter Award BIOS, press F8 while the operating system boots. This is the most common option. There are also the following entry combinations:

Now let’s talk about how to properly configure the BIOS. In most cases, this is exactly the problem. If you have an Award BIOS, do this:

  • Go to BIOS.
  • From the main menu, use the arrows on the keyboard to go to the “Integrated Peripherals” section.

Check that the switches of the USB controllers are in the “Enabled” position, if necessary, switch it yourself.

Go to the “Advanced” section from the main page and find the item “Hard Disk Boot Priority”. It looks like the one shown in the photo below. Pressing “” on the keyboard, move to the very top “USB-HDD”.

As a result, everything should look as shown in the photo below.

Switch back to the main window of the “Advanced” section and set the “First Boot Device” switch to “USB-HDD”.

Return to the main window of your BIOS settings and press “F10”. Confirm the selection with the “Y” key on the keyboard.

    Flash drive with Windows 7 installer

    In this case, we will use the Windows USB / DVD Download Tool.

    • First of all, go to the Microsoft website and download the utility from there to create a bootable flash drive.
    • Install it and start making a flash drive.
    • Using the “Browse” button, which will open the explorer, specify the location where the ISO image of the OS is located. Click on “Next” and proceed to the next step.

    In the window with the choice of the type of installation media, specify “USB device”.

    Next, the process of creating a drive will begin.

  • Close the window in the usual way and proceed with the installation of the system from the newly created media.
  • Try using a bootable drive.
  • This method is suitable for Windows 7 and later. To record images of other systems, use our instructions for creating bootable USB drives.

    In the following instructions, you can see ways to create the same drive, but not with Windows, but with other operating systems.

    If the BIOS does not see the bootable USB flash drive how to install

    Flash drives have now become an indispensable tool for storing and transferring information to a PC. Most personal computer users use flash drives to install Windows or Ubuntu. This is due to the fact that you do not need to write the image to disk, but you need to install directly from a USB flash drive.

    In addition, most laptop and computer manufacturers, such as Acer and Lenovo, are now making desktops and laptops without optical drives, further popularizing the installation of Windows from a bootable USB stick. When installed in this way, many laptop and desktop users have situations where the BIOS does not see the bootable USB flash drive. In this article, we will try in detail to figure out how to write an image to a USB flash drive, as well as deal with BIOS settings for the correct installation of Windows and Ubuntu.

    If you are faced with the fact that when you restart your PC, your flash drive is not detected, then the first step is to make sure that the flash drive is really bootable. The fact is that just copying files to it is not enough.

    How To Fix Asus No Boot Device, Boot Device Not Found, No Bootable Device,

    over, if you have an “absolutely working” bootable flash drive, since you have already installed the system from it many times, then we have to disappoint you: currently there are several types of boot systems and a flash drive running on one PC will not work on another. For success in this case, the system must be rewritten in a different way.

    Therefore, the main part of the article contains detailed instructions on how to properly write a bootable USB flash drive using various software. The following article contains recommendations for configuring different types of BIOS.

    Correct creation of a bootable USB flash drive for Windows

    To create a bootable USB flash drive for Windows 7, you need to download a licensed image. You can download it on the official page www.microsoft.com/ru-ru/software-download/windows7. To write an image to a USB flash drive, you need a proprietary Microsoft Windows USB / DVD Download Tool, which can be downloaded at www.microsoft.com/en-us/download/Windows-USB-dvd-download-tool. After installing the utility, you can start creating a bootable USB flash drive. After starting the utility, a window will appear in which you must specify where the image is located.

    After clicking Next. you will be taken to the device selection window for recording an image.

    In this window, you must click the USB device button. after which you will go to the choice of the flash drive.

    After selecting the required flash drive, click the Begin copying button. The process of copying the installation files to the USB flash drive will begin. Also, be careful, as all previously stored files on the USB drive will be erased.

    The inscription in the last window “Status: Backup completed” will mean that your bootable flash drive is ready.

    To install Windows 8.1, you need to download the official MediaCreationTool utility at http://Windows.microsoft.com/en-us/Windows-8/create-reset-refresh-media. After launching the utility, you will be taken to the OS version selection window, in which you need to select the language, version and bitness of the operating system.

    In the next step, you need to select a Windows recording device. In our case, this is a “USB flash drive”

    The next step will give you the opportunity to choose a USB flash drive.

    After that, the next step will be to download and write files to the drive. As with the previous example, all data on the flash drive will be erased.

    The last window will notify you that the installation drive is ready.

    To make a bootable flash drive for Windows 10, you need to download the MediaCreationTool utility from this page: www.microsoft.com/en-us/software-download/windows10. If you run the utility on Windows 7 or 8, the program will offer you two options: update or create installation media. You need to choose the second option.

    The step of creating a bootable drive will be similar to the example for Windows 8.1.

    AMI-BIOS

    The BIOS AMI has a gray screen, a blue font and a row of tabs at the top. The information block is on the right. Mouse control is also not available.

    bios, does, asus, bootable, stick
    • Section “Advanced”.
    • USB Configuration Menu.
    • Next to all the settings with the name “USB Controller” and “USB Function”, put the value “Enabled”.

    Now you can change the bootloader parameters:

    • Boot tab.
    • Boot Device Priority parameter.
    • Put a USB flash drive in the first place: “Patriot Memory” or “USB”.
    • Press Esc to go back to “Boot”.
    • Open “Hard Disk Drives”.
    • In “1st Device” select the flash drive.
    • To save your changes, go to the “Exit” tab. There will be an item “Exit Save”.

    Boot Legacy and EFI, Secure Boot

    The most common reason that a bootable flash drive is not visible in the Boot Menu is a mismatch between the boot mode that is supported by this flash drive and the boot mode set in the BIOS (UEFI).

    Most modern computers and laptops support two boot modes: EFI and Legacy, while often only the first is enabled by default (although it happens the other way around).

    If you write a USB drive for Legacy mode (Windows 7, many Live CDs), and only EFI boot is enabled in the BIOS, then such a USB flash drive will not be visible as bootable and you will not be able to select it in the Boot Menu.

    Solutions in this situation can be as follows:

    • Enable support for the desired boot mode in the BIOS.
    • Burn the USB flash drive differently to support the desired boot mode, if possible (for some images, especially not the newest ones, only Legacy boot is possible).

    As for the first point, most often it is required to enable support for Legacy boot mode. This is usually done on the Boot tab in the BIOS (see How to enter the BIOS), and the item that needs to be enabled (set to Enabled mode) may be called:

    • Legacy Support, Legacy Boot
    • Compatibility Support Mode (CSM)
    • Sometimes this item looks like an OS selection in the BIOS. Those. the item name is OS, and options for item values ​​include Windows 10 or 8 (for EFI boot) and Windows 7 or Other OS (for Legacy boot).

    Additionally, when using a bootable USB flash drive that only supports Legacy booting, you should disable Secure Boot, see How to disable Secure Boot.

    On the second point: if the image being written to the USB flash drive supports booting for both EFI and Legacy mode, you can simply write it differently without changing the BIOS settings (however, images other than the original Windows 10, 8.1 and 8 may still need to be disabled. Secure Boot).

    The easiest way to do this is using the free program Rufus. it makes it easy to choose which type of boot the drive should be written for, the main two options are MBR for computers with BIOS or UEFI-CSM (Legacy), GPT for computers with UEFI (EFI boot).

    Note: if we are talking about the original image of Windows 10 or 8.1, you can record it in the official way, such a flash drive will support two types of boot at once, see Bootable Windows 10 flash drive.

    BIOS does not see the bootable USB flash drive in the Boot Menu. how to fix

    Guides for installing Windows from a USB flash drive or just booting a computer from it include simple steps: set boot from a USB flash drive to BIOS (UEFI) or select a bootable USB flash drive in the Boot Menu, but in some cases the USB drive is not displayed there.

    In this manual, in detail about the reasons why the BIOS does not see the bootable USB flash drive or it does not show it in the boot menu and how to fix it. See also: How to use the Boot Menu on a computer or laptop.

    Additional reasons that the flash drive is not displayed in the Boot Menu and BIOS

    In conclusion, there are some more nuances that, in my experience, are not fully understood by novice users, which causes problems and the inability to boot from a USB flash drive in the BIOS or select it in the Boot Menu.

    • In most modern BIOS versions, in order to install a boot from a USB flash drive in the settings, it must first be connected (so that it is detected by the computer). If it is disabled, it is not displayed (connect, restart the computer, enter the BIOS). Also keep in mind that the “USB-HDD” on some older motherboards is not a USB stick. Read more: How to set boot from a USB flash drive to BIOS.
    • In order for the USB drive to be visible in the Boot Menu, it must be bootable. Sometimes users simply copy the ISO (the image file itself) to a USB flash drive (this does not make it bootable), sometimes they also manually copy the contents of the image to the drive (this only works for EFI boot and only for FAT32 drives). Perhaps it will be useful: The best programs for creating a bootable USB flash drive.

    It seems that everything. If I remember any other features related to the topic, I will definitely add the material.

    Why do I have only MBR in Rufus in the “partition scheme” options? After all, I understand correctly that MBR does not work on ufi?

    Perhaps because the image is like this, without UEFI boot support.

    Hello Dmitry. This is my situation. The disks are gpt-marked. Bootable USB flash drive Ventoy. Everything worked well before. But then there was a failure. The computer is frozen, ctrlaltdel went to reboot. For some reason, the BIOS reset the settings to factory defaults. After that, when choosing an image (any), I get an error no boot file found for uefi. Maybe the image does not support x64 uefi. What to do? Can you advise something? The system does not boot any. Neither Windows nor Linux. Stand on different disks.

    Hello Secure Boot, can it turn on? But this is just a guess (and in this case, in theory, he should behave differently)

    The article helped launch the installation! Thanks

    Hello Dmitry. Question. How can this be fixed? (table of volumes on disk) Why is volume 3 System and visible, and C: bootable with Windows? As I understood it is not correct.

    Hello. No, everything is ok, this is standard in your configuration. the FAT32 volume with the bootloader is indicated in the list volume as the system volume, and the volume from the OS itself, from where it is loaded, as bootable.

    Hello again. As it turned out, I got UEFI. I downloaded Easy UEFI from the Internet, before that I changed the GPT markup to MBR and managed to install Windows 10, during installation I partitioned the disk 512 mb, 1024 mb and for the 120 Gb system. Then I launched Easy Trial UEFI, efi bootloader was created (in a volume of 1024 MB.) But this section turned out to be not hidden. Then in iomi I changed MBR to GPT in BIOS changed everything to UEFI Windows10 starts. But I can’t install anything else. When I try to install Arcolinux, I get this error Falling back to interactive prompt You can try to fix the problem manually, log out when you are finished sh: can`t access tty: job control turned off Googled that this is somehow related to the bootloader uefi I tried to do this diskpart sel disk 0 sel patition 2 assign letter = b exit cd / db: \ efi \ microsoft \ boot \ bootrec / fixboot Then I get an error: “bootrec” is not an internal or external command, an executable program, or batch file. In general, I collect grain by grain how to solve it. I think that the matter is in / efi / boot. Somehow you need to reconfigure it. Do not know how. Can you help?

    I have no answer for the installation, Linux is not quite my specifics. The only thing, I googled now on the topic and did not see that it is connected with the UEFI bootloader in discussions, rather with the inaccessibility of some sections. And why bootrec does not work for you is also not clear. Windows original?

    Yes, Windows from the site’s office. I activate it in my account.

    Hello! An Asus laptop has a BIOS, but a hard drive with GPT partitions. The BIOS does not see a bootable USB flash drive with the MBR (NTFS) format. He sees a USB flash drive in GPT format (FAT32), but at the same time, when you select it via Boot, the already installed Windows is simply loaded. And in BIOS, the flash drive is called simply Mass Storage, although when I created it through Rufus I called it Windows.

    Hello. Apparently, you have enabled boot in UEFI mode on the laptop (the fact that the BIOS interface looks “standard” does not mean that the laptop does not have UEFI). If you burned a USB flash drive under BIOS (MBR), then you will not be able to boot from it until you enable Legacy boot in BIOS. If you recorded using FAT32 / GPT and still does not boot, you may need to disable Secure Boot.

    Thanks a lot! I struggled for 2 hours (Asus VivoBook 15 X512FJ-BQ475), the BIOS did not see the bootable USB flash drive until it found your instructions. 1) disabled Secure Boot Control 2) disabled Fast Boot 3) enabled USB (I don’t remember where exactly, now I’m not in front of my eyes) 4) saved and rebooted with an inserted USB flash drive with a Windows-10 image from offsite / when formatting and loading the image, I used the GPT option. for computers with UEFI (EFI boot) When you press ESC, a choice of loading from a USB flash drive appeared in the menu, then everything is normal.

    Hello, can you tell me what it means to activate USB and where to do it? For too long I have been fiddling with the BIOS, it seems that it just does not read a flash drive and any external media.

    Good afternoon, please tell me what to do. Faced such a situation when the “secure boot” and “fast boot” functions are disabled in the BIOS, but the “Legacy CSM” function does not appear anywhere. As it already became clear, I want to install the system on a new laptop with FreeDos. Since CSM will not be able to turn it on, I decided to saddle a bootable USB flash drive through Rufus with a GPT UEFI (non-CSM) partition, but to my regret, the BIOS never saw the bootable USB flash drive. And now I have no idea how to install at least some kind of system on it

    Hello. Here I would like to see how your BIOS interface looks like. One way or another, the desired item must be somewhere. Sometimes it still looks like an OS choice (between Windows and Other OS, where the first is UEFI, the second is Legacy).

    BIOS is from Asus, the latter is on their website (version 304). There is no OS choice in it, as well as the Legacy mode. I accidentally noticed that this BIOS reads only flash drives with FAT format (not FAT32), when I decided to flash the BIOS just in case, despite the fact that I was going to flash the same one, because it was the last one, so I took the old flash drive where it was saved FAT format. Reflashing naturally did not help. And since 10 Windows weighs more than 2 GB, it will not be corny to be seen on a USB flash drive with FAT format, so I have no idea what to do.

    Hello, we assembled the computer, UEFI saw the bootable USB flash drive, but during installation complained about the absence of the Sources \ install.wim file, as a result, they switched the download to CSM and the installation was successful, but many write that after the download needs to be returned to UEFI, after returning UEFI does not see the disk with Windows 10 installed what needs to be registered (done) for this, please tell me.

    Hello. There are two options: 1. Leave it as it is (that is, without converting the disk, we cannot return the UEFI boot already, perhaps where you read about it, you just misunderstood something). 2. Convert disc. This can now be done without losing the installed Windows 10, like this: https://remontka.pro/mbr2gpt-Windows-10/

    Hello! In the boot menu, my flash drive is visible, when I click on it, it just starts the previously installed Windows 7. And nothing else happens. I want to install Windows 8.1. Downloaded from the official site Windows 8.1 for one language. I have an HP laptop, legacy support is enabled, secure boot is disabled, in the legacy boot order the flash drive is in the first place. What to do?

    Hello. According to your description, everything should boot properly from the USB flash drive, or the message “Press any key to boot from CD / DVD” should appear and by pressing any key the installation from the USB flash drive should be started. How exactly did you record the bootable USB flash drive? And it happens that some just throw the ISO file on it (and so it will not load).

    Win7 in UEFI mode simply won’t install. No way. Various installers, assemblies, rufuses, multiboots. I tried everything in two days. Win7 is not installed in UEFI mode. Paradox. Hangs on the inscription “Starting Windows”. In CSM mode, the flash drive is not visible. With what it can be connected

    Have you tried another drive? And on the USB 2.0 connector

    Asus vivobook x540n did not see the bootable USB flash drive, but after dancing with a tambourine, I saw it recorded in GPT, but when I clicked on the flash drive in the boot menu, it quickly throws it into the BIOS.

    Hello. Samsung laptop np300e5c. Doesn’t see the flash drive at all. Working connector, flash drive too. Recorded via Rufus in the ICBM

    Hello. NTFS? Which boot device do you choose in BIOS?

    Hello, I can not start the Windows installer from a USB flash drive, (I wrote it down for UEFI), UEFI did everything right for me, disabled the secure boot, just the gigabyte logo and that’s it

    And in the BIOS, is the UEFI boot mode set? (that is, on motherboards with UEFI, Legacy may be loaded). We tried to connect a USB flash drive to another USB connector, it is better to try 2.0

    Hello Dmitry! I could not run the installation flash drive on a laptop (ACER Aspire), but I used the flash drive on other computers.

    Hello. Well, I seem to have described the possible reasons above: either the boot mode is not the one selected in the BIOS (Legacy instead of UEFI or vice versa), or Secure Boot is enabled. precisely, I will not answer, since there is not enough information in the question.

    Greetings, I have an acer predator helios 300 ph317-52, the flash drive does not see how, and in boot, which in the BIOS and in the boot menu, which is called separately, cannot be translated into legacy either, because in boot mode there is only the uefi item what to do, tell me?

    Hello. Is the flash drive exactly made for UEFI? Because according to the description it looks like no. Well, try to disable Secure Boot.

    How to enable USB Drive boot option in ASUS

    Hello! I have a 2008 Asus laptop with Windows Vista Home installed. Recently, it began to reboot endlessly (due to a blackout), I decided to create a bootable USB flash drive with a system image (I did it through Rufus (MBR mode) and UltraIso (USB-HDD mode)) and restore the system. But the laptop does not see the USB flash drive, the system boots immediately, then reboots. In BIOS, I have the first boot queue set. Removable Device. I decided to remove all boot options in the BIOS at all (leave only the USB flash drive). after the reboot, the message “Insert bootable disk” appeared. I checked the composition of the ISO image and what was written on the USB flash drive. the composition of the files is the same. Why can’t the laptop see the USB stick? Thanks in advance for your reply.

    Hello. It’s so hard to guess. And if you do not set the boot order, but call the Boot Menu (usually the required key is indicated on the first screen below). is there a flash drive in the list? What happens when you choose it?

    Hello! I installed 8.1, a month ago I activated it using KMS Auto Net, everything seems to be fine, but I don’t remember exactly after what, but after a month the laptop began to reboot for about 20-30 minutes, attempts to put something in the BIOS, they didn’t give anything, downloaded the ISO 8.1 image via UltraIso, try to reinstall, there is no flash drive in the BIOS, which I just did not do, inserted the USB flash drive into the laptop, opened the device, there are 7-8 files, I press Setup and run on behalf of Adm. and the installation of Windows 8.1 went. How can I understand?

    Hello. Perhaps the USB flash drive was recorded for the wrong type of boot. Although, on the other hand, through UltraISO it should be suitable for both Legacy and UEFI (although it may still depend on the specific image). Or maybe something was wrong in the BIOS (but you can’t tell without seeing the picture). Well, the fact that after the setup the installation went. this is normal, for this it is needed to start the installation in an already running system.

    thank you very much for answering, good site.

    I created a bootable USB flash drive on a 16 GB flash drive, the BIOS did not see it, my friend prompted to take a smaller flash drive, it was good for 7 GB, I didn’t have to buy, and that’s it, the BIOS saw.

    At the very beginning of the installation, the laptop simply turns off without any explanation of the reason or error

    Hello. And why was it originally decided to reinstall? Not due to any existing power and on / off problems?

    Hello! The computer is not a kind of USB flash drive for installing Windows, I’ve already tried everything, created an image, wrote it down through iso, boot is invisible

    Hello. How exactly was it recorded, with what program? For what type of download?

    Thank you so much, thanks to your article I just understood why the computer does not see the USB flash drive!

    Dmitry, hello. I read the article and all the Комментарии и мнения владельцев, but I did not find an answer to my specific situation. You understand this issue for sure, maybe it will be possible to prompt immediately. Such situation. The bootable USB drive was created from the office. site through the Microsoft Media Creation Tool. That is, as I understand it, it should be ready for installation at the same time: via BIOS on MBR and via UEFI on GPT. I have an SSD marked under GPT, I want to install it in UEFI, but in the BIOS of my not newest laptop, there are only two options for choosing the boot format, these are either UEFI / Legacy, or only Legacy. There is no option to select only UEFI. And if I choose the UEFI / Legacy option, and set the boot priority of the flash drive, then when saving and rebooting, it is not detected and the existing SSD system is loaded. If I make UEFI boot unavailable, then the flash drive is detected upon reboot and Windows 10 is ready for installation. I do not understand the following points: 1. If I continue the installation, it goes through and everything in general is ok, but it turns out that it happens in Legacy, but how, because my SSD is marked under GPT. 2. If, after such an installation in BIOS, I choose to boot UEFI / Legacy back, will my system, installed as indicated above, start in UEFI mode? 3. This bootable USB stick created by Microsoft Media Creation Tool is labeled under MBR. Is that how it should be? Considering it needs to be UEFI. GPT / BIOS. MBR boot ready? 4. What is the best way to proceed in my situation, after all there is the possibility of booting UEFI, a GPT disk and I want to use this particular option?

    BIOS does not see the bootable USB flash drive in the Boot Menu

    We tell you what to do if the BIOS does not see a bootable USB flash drive for installing Windows.

    To reinstall or programmatically repair Windows, you need an external media containing the operating system. It can be connected to a computer during the boot phase and used to solve problems with system files or reinstall the OS.

    Previously, disks were used for this, now. flash drives. The problem is that the laptop is not always able to recognize the USB drive during the startup phase. Naturally, this prevents users from reinstalling Windows.

    Usually problems arise in two cases:

    • or a person incorrectly wrote the installation files to the USB flash drive,
    • either configured the BIOS incorrectly.

    Create a bootable Windows USB flash drive

    To create a full-fledged bootable flash drive, you need special applications. It’s not enough to just upload a Windows image onto a USB drive. The whole process looks something like this:

    • We go to the official Microsoft website, select the Windows version that we need, specify the language and click on the “Download” button.

    Microsoft currently only offers to download Windows 10. If you want an earlier version, you will have to look elsewhere. But we recommend using only licensed and most “fresh” software. The instructions below are also suitable for older versions of Windows.

    • Then download the Rufus app.
    • Install Rufus and run it.
    • A small window will appear in front of you with a number of fields that must be filled in:
    • Device: here you need to select a USB flash drive from which we will make a bootable one. Naturally, it must be inserted into one of the USB ports in advance.
    • Download method: here we click on the “SELECT” button, look for the system image downloaded from the Microsoft website and double-click on it.
    • Partition scheme: Usually this item does not need to be changed. Unless you have some old OS or specific hardware.
    • Target system: leave “BIOS or UEFI”.
    • New volume label: write any name for the bootable USB flash drive. You can simply specify the version of Windows that is stored on it.
    • File system: if desired, change to NTFS. Windows supports this format, but all other systems do not.
    • Cluster size: keep the same.

    USB boot, new BIOS, problem solved

  • Having filled in all the parameters, click on the “START” button and wait for the system image to be written to the USB flash drive. Only after that it will be possible to use it as a bootable.
  • The screenshot shows the parameters for the Ubuntu operating system, but they are also suitable for modern versions of Windows.

    Configuring the BIOS

    Now that we have a working bootable USB drive, proceed to the next step.

    But before going into the BIOS settings, we will try to boot through the Boot Menu and select the USB flash drive there again (we again and correctly recorded Windows on it). Boot Menu is a special interface that allows you to display on the screen all available memory drives connected to the computer. And also choose the one from which you want to boot. It works like this:

    During launch, press one of the keys:

    • F11. for MSI, AsRock motherboards and Sony Vaio laptops.
    • F12. for Gigabyte motherboards and for Acer, Dell, Lenovo laptops.
    • F8. for Asus motherboards.
    • Escape. for Intel motherboards and for Asus laptops.

    This is necessary in order to go to the boot menu and select our USB flash drive as the boot device.

    • In the menu that opens, we are looking for a USB flash drive on which Windows is written.
    • Select it and press the “Enter” key (Enter).

    This is how the boot menu (or Boot menu) looks like.

    If you could not start the Boot Menu or the desired drive does not appear in it, then proceed to fine-tune the BIOS.

    Award

    This is one of the popular BIOS options that some motherboards still use today. To configure it to work with a bootable USB flash drive:

    • Turn on the computer.
    • Press one of the keys to enter the BIOS menu.
    • Once in the corresponding menu, use the arrow keys to go to the Integrated Peripherals sub-item.
    • Inside, closer to the center, you can find the item USB Controller or USB 2.0 Controller. Select each of them and use the “Enter” key to change the value to Enabled (if it is already set, then nothing needs to be changed).
    • Exit the Integrated Peripherals menu (by pressing Esc).
    • Open the Advanced BIOS Features sub-item.
    • We are looking for the Hard Disk Boot Priority column there and go to it.
    • We will see a list of all connected drives and drives. Select our flash drive (USB-HDD) with the cursor and press the Page Up key to move it up and set the maximum priority when loading.
    • Go back by pressing Esc again.
    • Go to the First Boot Device menu and press “Enter”.
    • In the list that appears, select the USB-HDD item. Now the flash drive will become the highest priority device when booting.

    Another kind of BIOS. In this interface, the menus and access to the functions we need are organized differently.

    • Turn on the computer.
    • Launch the BIOS by pressing the appropriate key.
    • Once in the BIOS, immediately go to the Advanced tab by clicking on the arrow to the right.
    • In the list of options that opens, look for the USB Configuration sub-item and open it by pressing the “Enter” key.

    The basic settings of USB devices are hidden here.

    • Change the values ​​of the USB Function and USB 2.0 Controller items to Enabled.
    • Then go to the Boot tab.
    • Inside, look for the Hard Disk Drives submenu and go into it.
    • There will be several connected drives here. We are looking for our flash drive (Patriot Memory) and set it to the highest priority, moving it to the top of the list.
    • Then we return to the Boot tab and this time go to the Boot Device Priority submenu. There we set the same priority as in the previous paragraph.
    • Well, at the end, we save all the settings. Press the F10 key, and then Y.

    After that, the computer will reboot and try to use the USB flash drive as a boot device.
