exit

1. Type the following command to run the System File Checker offline and press Enter:

sfc /scannow /offbootdir=F:\ /offwindir=C:\Windows

In the command, we are using the /offboodir option to specify the drive letter of the System Reserved partition, which in this case is F. Also, the /offwindir option specifies the location of the Windows 10 files, which in this case is C:\Windows.

1. Click the X button to close Command Prompt.
2. Click on Continue.

Once you complete the steps, the command tool will fix any problems with system files on Windows 10, and the device will restart normally.

If this doesn't repair all then run:

dism /online /cleanup-image /restorehealth
