What to do if Windows does not start
Fix errors We will be in Windows 10. But in Windows 8 and 7, the recovery process occurs about the same.
In such cases, the screen with the OS logo does not appear. Instead, it displays a black background with various errors.
Disconnect peripheral devices
The system may not be loaded due to a malfunction of one of the connected devices. Try disconnecting USB drives, cartriders, printers, scanners, cameras, microphones and other support techniques.
After turning off, restart the computer. If it does not help, temporarily disconnect the keyboard and the mouse, and then press the reboot button again.
Check the boot disk status
BIOS is the name of the layer between Windows and the hardware part of the computer. the download settings could be knocked. For example, if an incorrect disk is specified as the OS file source, the device simply does not find them when turned on and therefore cannot start the system.
Immediately after starting, press the BIOS input key until you see the settings menu. Depending on the PC manufacturer, it can be F2, F8, Delete or the other key. Usually the desired option is displayed at the bottom of the screen immediately when the computer is turned on.
Once in the BIOS settings, find the BOOT section and check whether the Windows system files are set to first place in the download list. If not, move it to the very top. The appearance of the BIOS may differ from you, but its structure is always about the same.
Select “Save and Exit” (Save and Exit) to apply changes.
After that, the computer will reboot and the problem may eliminate.
If the previous method did not help, a larger failure could occur in the system. In this case, it is necessary to perform a reset BIOS. How to do it, lifehaker already wrote. After that, files on drives and Windows settings will remain intact. But, most likely, you will have to go to the BIOS, find a section with time parameters and dates and set them up.
The system starts slowly, but works
The most simple problem in solving. All you need to do is go back to the previous version of the OS, which you had before you decide to upgrade. Do not need to download anything. It is enough to wait for loading, whatever it is (more than 40 minutes. it is unacceptable, then the OS will not load). Next, go to the system parameters (opens with the right button to “My Computer”) and select item: System Protection.
A new window will open, where you will find the parameter “Restore state from the control point”. Choose it and click the “Next” button. You will see all the available points with the date when they were created. If the problem arose after the start of the update through the official installation center, then today will be today’s date. Before starting Windows 10 updates always makes the point, just for such situations. Choose any, click “Next” and follow the instructions on the screen.
There is another way, but he is radical. If the OS operationer works, you can always roll back to factory settings. To do this in the control panel, find the “Update and Security” item, where to go to the category: Return the computer to the original state. Select this item and OS will offer the following:
Note that even in the “Save My Files” item will lead to the fact that you lose part of your data. This is especially true for the established. It will disappear, and you will need to re-download Microsoft Office, Excel and other utilities. Add our site to bookmarks to quickly restore everything you need.
Black screen after updating the system to Windows 10: Causes and Solution Ways
Failure could happen unnoticed for the user in the update process. To restore the system, it is enough to repeat the update process and the black screen will disappear.
Conflict updated to Windows 10 system with previously installed video card drivers
It is somewhat more complicated. First you need to just get into the system.
If a solid black screen appears when booting Windows 10, but then the OS is still loaded, then take the following actions after each of which restart the computer:
- Press successively “Start. Control Panel. Power Supply. System parameters “and on the last tab, uncheck the checkbox” Enable a quick start (recommended) “options for completing work, after which save the settings. Turning off quick launch
- Right-click on the pictogram with the image of the computer, which is on the desktop or in the Start menu, and select the “Properties” tab from the drop-down list. Then followed by “Equipment. Device Manager. Video adapters “, before opening the name of your video card. Continue right-click on the name and select “Update Drivers”. You can do this in automatic mode via the Internet or in a manual from the computer, after downloading the necessary software from the site of the video card manufacturer.
If you see only a black screen during Windows 10 boot, you first need to log in using a safe mode, and then then do everything described above.
Necessary actions to enter safe mode:
The restart of the computer and the system is loaded in safe mode.
Also enter safe mode using the Windows 10 installation disk, and when it is not used to use the eighth version of the system:
After opening the first window, click the “Next” button.
The first pop-up after starting the disk window
In the window that opens, click on the link “System Restore”
In the future, the system starts in safe mode goes in the same sequence as shown above.
Automatic redirection to second video card connector
Connect the monitor to the free socket of the video card, which is located on the back of the system unit.
Boot Failure and An Operating System WASNT FOUND Errors
Another common version of the problem with starting Windows 10. Black Screen with Boot Failure Error Text. Reboot and Select Proper Boot Device or Insert Boot Media in Selected Boot Device or An Operating System WaSn’t Found. Try DisconNecting Any Drives That Don’t Contain An Operating System. PRESS CTRLALTDEL TO RESTART.
In both cases, if this is not the wrong order of loading devices in BIOS or UEFI and not damage to the hard disk or SSD, almost always the cause of the start-up error is a corrupted Windows 10 bootloader. Steps to help fix this error are described in Instructions: Boot Failure and An Operating System WASNT FOUND in Windows 10.
What to do if everything the previous one did not help
If the above does not help, then as an option, you can reinstall Windows OS (if some system files were damaged or the system is infected with the virus. this is the only alternative).
By the way, a good option (for those who do not want to lose the old system with all data):
- Create on a hard disk another section under the installation of a new Windows OS (using LiveCD or Special. Utilities for working with HDD. this can be done quickly and without loss of data);
- Next, install Windows to this section of the disk;
- Then you can “save” old Windows and pick up all the necessary files that were on the section;
- After that, the old disk partition can be formatted and attach it to any other section (also with the help of special. utilities, the link led above).
Either, you can try to restore Windows using special tools that are on LiveCD (DVD / USB). Such an emergency carrier will allow you to check the system for viruses, evaluate the status of the hard disk, remove some errors, etc.
True, it must be prepared in advance, or use another PC / laptop.
And here you and one more very good, and most importantly, an effective way that will help in principle to avoid our current situation. Since the problems appear after updating Windows 7 (programs are not launched, system failures are observed and so on), you can simply refuse this process. To be honest, now there are very many “pirates” in advance and do. While installing the operating system, at the very end, you can choose “Do not download updates” and then rejoice in life.
If you did not do this, then you always have the opportunity to correct the situation. To do this, it is enough to find the “Windows Update Center”, and then go there in the settings. Now select “Do not update never” and save the changes. That all problems are solved. Now you can not be afraid that you will have problems. You will always independently check the “updates”, and then choose those that you really need. As a rule, these are just drivers for equipment. They do not carry any danger.
But there are some more pretty interesting and simple solutions that will help us solve problems after updating Windows 7. What exactly? Now we will try to figure it out.
Most Windows updates have software for externally connected and built into the motherboard devices, including video and audio card, chipset, communication inertes, and T.D. If problems are connected with this, there are two explanations:
- Drivers downloaded during update are not suitable for a particular device.
- If the update is global, t.E. The system is updated completely, one or more devices may simply not be a working version of the driver under Windows 10. In these cases, the system uses earlier software versions that may be incompatible with the latest revision of Windows. This is usually observed with devices built into the motherboard.
The situation with incompatible drivers usually arises from the owners of computers, which were originally created under a certain version of Windows OS. It is easy to determine the year of the motherboard. For example, if at the time of its receipt on sale the last version was Windows 7, perhaps a computer under it and was created.
Run the last successful system configuration
If the Windows system does not start after the update, you can use its latest successful configuration. In the operating system itself there is such an opportunity.
- Press the “POWER” button to turn on the computer.
- Before the appearance of the Windows logo during the computer boot, hold down the “F8” key. If the operating system is loaded, restart the computer and try again.
- The screen will open to select Windows Download Options. Using the “Up” and “Down” buttons, select “Last Successful Configuration”. To confirm the selection, press the “ENTER” key.
- Wait for the end of the standard operating system boot. Windows work will be restored as well as before installing updates.
If possible, you can try to boot in safe mode and roll back the system to one of the recovery points:
- Press the “POWER” button to turn on the computer.
- Before the appearance of the Windows logo during the computer boot, hold down the “F8” key.
- The screen will open to select Windows Download Options. Using the Up and Down buttons, select “Safe Mode”. To confirm the selection, press the “ENTER” key.
- Wait for the operating system download.
- Click the Start button and go through the items in the following sequence: “All Programs”. “Standard”. “Service”. “Windows Recovery”.
- Select one of the system recovery points when updates have not yet been installed.
- At the end of the recovery, restart the computer.
Important! If two or more operating systems are installed on the computer, after switching on, you must select the desired Windows OS. Immediately after that, press and hold the “F8” key.
Solutions of problems with downloading Windows 8 and 8.one
The way to solve problems with downloading Windows 8 and 8.1 depends on what exactly led to the emergence of faults. Most of the problems associated with the operation of drivers or system applications can be triggered by rollback of installed updates. From that and start.
Rollback of updates
You can use the update rollback function from Windows or using a boot flash drive or disk. The main complexity when using the first method is the need to load the operating system. T.to. In the usual mode it is impossible, it remains only to try to start the OS in safe mode. You can do this using the F8 keystrokes or the SHIFT F8 combination at the original load of the computer (after the logo of the manufacturer’s motherboard appears on the screen). If the reason for the hang is incompatible drivers or settings of system parameters, then Windows will have to start successfully.
- Press the keyboard shortcut “Win X”.
- Above the “Start” menu will appear a list of various functions, select “System”.
- In a new window, click on the “Advanced System Parameters” item.
- In the left side of the window that opened, select “System Protection”.
- One window will open, go to the “System Protection” tab, then click on the “Restore” button.
- Click “Next”.
- Checkpoints (recovery points) are displayed on the screen.
- Choose by date of the recovery point when the system loaded without problems.
- Click Next and follow the instructions.
If you manage to log in to safe mode, it remains only to use the second way to roll back the updates:
- Download from disk or flash drive with Windows Installer.
- As soon as the “Set” button appears on the screen, click on the “System Restore” item in the lower right corner of the screen.
- Go successively. “Diagnostics”, “Advanced Options”, “System Restore”, “Windows 8” (or “Windows 8.one”).
- The “Restore System” window will appear on the screen with existing recovery points.
Deleting manual updates
To take advantage of this method, Windows also need to be downloaded in safe mode. Then:
- Go forward. “Control Panel”, “Programs”, “Programs and Components”, “Installed Updates” (Last item is located on the left side of the window).
- A window with a list of installed updates will appear on the screen.
- Find the last update by date, click on it right-click and select “Delete”.
- Follow the instructions.
If the remote update was the cause of the malfunction, the problem will be solved.
Removing manual drivers
Here you will also have to download Windows in safe mode. After that, follow these steps:
- Press the “WinX” keyboard keyboard, then select Device Manager.
- The screen displays a list of all devices installed in the system system.
- Among them you need to find the one that has been updated in the last update of the system.
- To do this, click twice as a mouse by the name of the device.
- Go to the new window in the tab “Details”.
- In the list of “Properties”, select “Date of Last Receive”.
- If in the “Values” section appears the date that coincides with the date of the last update, then you found the updated recently driver.
- Next, go to the “Driver” tab and click on the “Disable Device” button.
- Restart your computer.
- If Windows is successfully loaded in normal mode, open the Device Manager again, right-click on the device name, then select “Delete Device”.
- Install the driver manually (you have to search the Internet if it is not available on a computer or on a disk).
Bios Reset Settings
If the cause of faults are BIOS settings, this can be solved in the following way:
- Go to the BIOS settings, for which you press the “F2” or “Delete” key immediately after turning on the computer (it is possible that you should press another key in your case. depends on the motherboard model).
- On the first page of the settings or in one of the partitions, find the “Restore Bios Defaults” function, “Load Factory Defaults” (Function may be called differently).
- Highlight the function by the arrow on the keyboard, then press the “ENTER” key.
- To save the settings, click “F10”, agree with changes.
- The computer will reboot.
Returning Systems to factory settings
If nothing of the above helps, only one output remains. perform a complete reset of Windows. This procedure is comparable in time with reinstalling the system, however it will not require the user to perform any settings (for example, you do not have to select a hard disk section for installation). To reset Windows, you will also need a loading flash drive or disk:
