  • In the “Start” menu, click on “Settings” and select “Update and Security”;
  • Open the “Restore” tab and under “Special Boot Options” click on “Restart”;
  • The device reboots and we see the window to select the action. Once you’re in the right menu, do everything the same as in the previous point when running the BIOS on Windows1.

If when using this or the previous method you did not see the “UEFI firmware options” button on the screen, it means either that this notebook has an outdated version of BIOS without UEFI, or that the OS was installed on the laptop in Legacy mode. Then work with UEFI is not available from the operating system. you will have to use the first two methods.

Booting a Lenovo laptop from a flash drive through BIOS

Most often this operation is performed by specialists in order to cure a laptop from viruses. Various programs are written to removable media, but to boot from it, as a rule, is not so easy. The problem is that all the latest models of Lenovo laptops, starting from the release of 2013, have the UEFI BIOS software, which has a certified Secure Boot key. They allow you to boot your laptop only when using a licensed installation disk Windows 8.

To boot from the media in this BIOS, you must disable Secure Boot, following these steps:

  • Immediately after turning on the laptop, press the two Fn F2 keys on the keyboard, or use the Novo Button to enter BIOS.
  • Entering “InsydeH20 Setup Utility” (as a rule, all the latest Lenovo models have it), go to the “Security” section.
  • Then select “Disabled” under “Secure Boot”, thus disabling the security protocol.
  • Change the “UEFI” setting to “Legacy Support” in the corresponding “Boot” section.
  • Save the changes you made by going to “Exit” and selecting the “Exit Saving Changes” option. From the options suggested by the computer choose “Yes” and wait for the reboot.
  • Insert the removable drive into a free USB input and go back into the BIOS by pressing the necessary keys for this model of Lenovo.
  • Under “Boot” we can see the USB flash drive. It is usually written in the menu as USB HDD. Press Fn F6 and find the media first in the list of devices to boot the system.
  • Repeat the actions described in step 5.

After all the steps the notebook will boot from the flash drive as follows.

Note that for some Lenovo models, disabling only one Secure Boot option may not be enough. You may need to enable compatibility mode to boot the system from removable media.

On various models it may be called as CSM OS, CSM Boot, Legacy BIOS, UEFI and Legacy OS or just CSM.

How to enter the BIOS on Lenovo computers?

Lenovo is one of the largest companies in the world that make computers. And since the demand for the products of this company is growing, the questions of correct operation and maintenance of Lenovo equipment are more and more actual for users. And for those who have decided to reinstall Windows, at the very beginning of the process raises the question: how to enter the BIOS in Lenovo?

To begin with, it’s worth understanding what BIOS is and what it’s eaten with. So, the BIOS in Lenovo is a special microscopic program that provides correct and stable interaction between all the components of the PC and the OS and allows you to configure it. And BIOS setup is a standard PC setup that helps the system figure out which functions should be activated and how they should be booted. The BIOS is on any computer, whether it’s a Lenovo B560, Lenovo S21 or M5400.

To date, several different versions of the Bios have been created, which differ slightly in appearance, but in terms of functions. everything is identical here. Each version is used for the initial setup of the computer and for testing it. The BIOS functionality includes:

  • Setting the date and time;
  • Selecting the boot sector. the device from which the operating system will be installed or loaded;
  • System components check, which includes checking the health of RAM and hard disks;
  • Connecting security. a password on your laptop to protect your personal data.

Auxiliary Novo Button

The Novo button is not available on all laptop models, so you will need to try to find it. It launches the “Novo Button Menu”, but let’s take our time and try to find it. It comes in two varieties.

  • The first version is a regular button with a curved arrow or inscription (NOVO). It’s usually right next to the power button on the laptop. Just press and hold it when you restart or turn on your computer.
  • The second kind. the button is recessed and looks like a small hole. You need something thin to push it, like a needle or a paper clip. Here you have to look for it, because it can be located anywhere. As a rule the developers place it near the power supply input.

Once the “Novo-menu” starts, just choose “BIOS Setup” from the list. If you need to boot from a certain medium then choose “Boot Menu”.

How to get out

From what we have said it is easy to enter BIOS. But sometimes there is a reverse question. how to make the exit to BIOS on a Lenovo laptop. To do this, just press the Esc button, and then save the entered information or exit without saving. In the extreme case, you can long press the Power button and wait for shutdown. After that you can boot your PC and enter the OS in the normal mode.

Windows options. special boot options

Parameters of the operating system Windows 10 allows you to reboot the laptop with a direct transition in BIOS. This instruction is universal and suitable for all models of not only Lenovo laptops, but also other manufacturers.

To log in to the base system via Windows on Lenovo, proceed as follows:

  • Click on the Start menu button in the bottom work panel on the left;
  • Select the gear icon, which denotes system settings;

This way is suitable if the operating system starts and operates correctly. If your laptop does not have an operating system or it is “lost,” you will have to use the options described above.

Where to open the BIOS setup in Windows 8?

If you are using an operating system from “eight” and newer, you probably can not see the key to enter BIOS on a black monitor when you start your PC. Let’s assume that your notebook is not equipped with a mechanical NovoButton and the FnF2 combination is not working by default. The following steps should be taken:

  • Hover your mouse cursor over the right side of the display and select Settings;
  • At the bottom of the window that opens, click “Change computer settings”;
  • Click on the “General” subsection and find the “Special Boot Options” item in the window to the right;
  • It remains to press the “Restart Now” button and confirm the action by clicking Enter;
  • The notebook will be automatically switched off and will be switched on with the BIOS-menu active.

How to enter the BIOS on a laptop Lenovo

Lenovo. one of the most popular manufacturers of laptops. By the way, I must tell you (from personal experience), laptops are quite good and reliable. And there is a feature at some models of these laptops. unusual log in BIOS (and to enter it very often it is necessary, for example, to reinstall Windows).

In this relatively short article, I would like to review these login features.

Entering BIOS in Lenovo notebook (step-by-step instruction)

1) Simply press the F2 (or FnF2) button when you start your Lenovo notebook (most models) to enter BIOS.

However, some models can react to these keys without any response (for example Lenovo Z50, Lenovo G50, and the whole range: g505, v580c, b50, b560, b590, g50, g500, g505s, g570, g570e, g580, g700, z500, z580 may not respond to these keys).

2) The above models have a special button on the side panel (usually next to the power cable) (e.g. Lenovo G50, Lenovo G50, Lenovo G50, etc.). Figure. 2).

To enter the BIOS, you need to: turn off the laptop and then press this button (it usually has an arrow on it, although I admit that on some models may not be an arrow).

By the way, an important point. Not all Lenovo notebook models have this service button on the side. For example, on the Lenovo G480 notebook. this button is next to the power button on the notebook (see “Lenovo G480”). Figure. 2.1).

3) If everything is done correctly, the notebook should turn on and the service menu with four items should appear on the screen (see “Service Menu” on page 28). Fig. 3):

Select BIOS Setup to enter BIOS (BIOS setup).

4) Next you should see the most common BIOS menu. From here you can configure BIOS like for other notebooks (settings are almost identical).

By the way, may be someone needs: In Fig. Here are the settings of the BOOT partition of your Lenovo G480 laptop for installing Windows 7 on it:

  • Boot Mode: [Legacy Support]
  • Boot Priority: [Legacy First]
  • USB Boot: [Enabled]
  • Boot Device Priority: PLDS DVD RW (that’s the drive with the Windows 7 startup disk installed, note it’s listed first), Internal HDD.

After changing all the settings, don’t forget to save them. Select “Save and exit” in the EXIT section. After rebooting notebook. Windows 7 installation should start.

5) There are certain models of laptops, such as Lenovo b590 and v580c, where you may need to press the F12 button to enter BIOS. Holding this key immediately after turning on the laptop. you can get to Quick Boot (Quick Menu). where you can easily change the boot order of the various devices (HDD, CD-Rom, USB).

6) And quite relatively rarely the F1 key is used. You may need it if you use a laptop Lenovo b590. The button should be pressed and held after powering on the device. BIOS menu itself is not very different from the standard.

The manufacturer recommends to charge the laptop battery enough before entering the BIOS. If in the process of setting and configuring settings in the BIOS, the device will crash (due to lack of power). there may be problems in the further operation of the laptop.

To be honest I’m not ready to comment on the last recommendation: I’ve never had any problems with turning off the PC while in the BIOS setup.

Resetting BIOS settings on your Lenovo laptop

As said above, BIOS and its settings are stored in the CMOS chip on the motherboard. Use a CR2032 type battery to power it. a large flat “tablet”. It powers the CMOS chip, even if the notebook is completely de-energised. To reset the BIOS to zero, just remove the battery for a few seconds. It sounds easy, but in fact you will have to take apart half of the notebook by removing the bottom lid and some hardware.

In most cases you will need to do the following:

  • Remove the plastic seal between the keyboard buttons.
  • Remove the keyboard itself and disconnect its cable from the motherboard.
  • Remove the battery.
  • Remove the screws and remove the bottom cover.
  • Remove the optical drive by removing the retaining screw.

This is sufficient for most notebook models. Some may have a steel cover plate under the bottom cover. Finally reach into the battery and pull it out of the holder for a few seconds. After that the BIOS settings will be reset, but you will be able to enter it again.

An alternative reset option is to find the jumper next to the battery. This is a 3-pin switch that normally has a jumper put on pins 1 and 2. If you move it to pins 2 and 3, the BIOS settings will also be reset. You’ll have to reconfigure everything again, but it’s easier than reflashing your laptop.
