This article contains the most common errors when you start Windows 10, and how to fix them. We hope this information will make life easier for those who switched to a new version of the system and suddenly found themselves between a hammer and an anvil.
1. Windows 10: “The computer is not running properly”
The first common problem when starting Windows 10 is that the system reports a certain critical error (CRITICAL_PROCESS_DIED, INACCESSIBLE_BOOT_DEVICE), and then displays the blue screen “Automatic Recovery” with the text “The computer is not running correctly”.
Automatic recovery: the computer is not running correctly
The reason for this error, in most cases, is the corruption and deletion of system files or entries in the registry. This can be caused by installing and uninstalling programs, or by using antivirus or utilities to clean the Windows registry.
The solution is to restore the files and registry entries that are corrupted:
- Click on the button Extra options on the blue screen, select Troubleshooting > Extra options > Boot Options.
- Click Reload.
- In the window Boot Options press the F6 key or the number 6 on the numeric keypad to start safe mode with command line support.
- The computer will reboot in safe mode, and the command line will automatically open. In it, enter:
sfc / scannow
dism / Online / Cleanup-Image / RestoreHealth
The computer will restart and after that the Windows startup will be performed in normal mode.
2. Windows 10 does not load beyond the logo
Another known problem is that the system boots up to the Windows logo, after which the computer spontaneously shuts down. The cause of this error is also the damage to the system files, however, unlike the first case, the damage is so serious that the system can not start the recovery itself.
In this case, you will have to create an emergency Windows recovery disk on another PC with Windows 10:
- In the Windows 10 Control Panel, locate and select Recovery > Creating a Recovery Disk.
- In the displayed window, set the parameter Back up system files to the recovery disk and press DNext.
- Connect an empty USB drive to the computer. Select it in the recovery disk creation window and click Further > Create. Wait until the file is copied and press Done.
- Remove the USB drive from the computer, connect it to the one on which Windows 10 does not start, and enable the download from it in the BIOS.
- The Windows Recovery Environment starts. In it you need to choose Restore the system image, or item Command line, and then enter in it the commands from the instruction to solve the first problem.
Windows Recovery Environment
You can also start the system recovery environment from the disk from which you installed Windows. To do this, you must boot from the installation disk, in the bootloader instead of Install press System Restore. In the menu that appears, select Troubleshooting > Extra options. The same options window as above will be displayed.
After recovery, the computer will be rebooted. Boot to the BIOS from the hard drive, and the system should start correctly.
3. Errors of “Boot Failure” and “An operating system wasn‘T found’
In some cases, when you start Windows 10, instead of loading the operating system, a black screen appears with one of two errors:
- Boot failure. Reboot and Select Proper Boot device or insert boot media in selected boot device.
- An operating system wasn‘T found. Try disconnecting any drives that do not contain an operating system. Press Ctrl + Alt + Del to restart.
The reasons for this error can also be two:
- Invalid boot device order in BIOS or UEFI. Verify that you are booting from the same drive on which Windows 10 is installed.
- Damage to the system loader. In this case, you will also need an installation disk or a recovery disk for Windows 10. After booting from it, in the recovery environment, you need to select the item Acronis Startup Recovery Manager and let the bootloader files be overwritten.
Also, the problem may be hardware damage to the hard drive from which the download is made.

4. Windows 10 does not start: black screen
A common error when starting Windows 10 is a black screen with no signs of loading the desktop, with or without a cursor on the screen. This often happens as a result of incorrect installation of any drivers: after reboot the computer works, but the OS does not boot.
Windows 10: black screen
In most cases, the solution to the problem lies in the system rollback. This will also require an installation disk or a Windows 10 disaster recovery disk. After booting from it, you can try to select the item in the recovery environment System Restore.
This will allow the system to roll back to the state before the problem occurs. The system prompts you to select the recovery point to which the rollback will be made, and after the confirmation will execute it. As a rule, after a restart, the black screen disappears.

5. Long boot Windows 10 at power on
There is a situation when Windows 10 does not load, the waiting icon is spinning, and that’s it. In fact, most likely, nothing bad happens – the system simply installs the updates that it downloaded when you last used your computer.
Windows 10 takes a long time to load
In this situation, it’s best to just wait. A similar state can last several hours depending on the number and volume of downloaded updates. It is recommended not to disconnect the computer, but leave it in the boot state for 1-2 hours.
To prevent this error from starting Windows 10 again, you can configure the computer to update on a schedule, and the system will not download updates without your knowledge. For information on how to edit update policies, see our instructions for setting the Windows 10 activity period.
