Hi STW,
I'm Sumit, here to answer your query at the Microsoft Community.
Please run chkdsk and see if it helps.
Perform a hard shutdown two times during the Windows boot screen. On the third time, Windows should boot to the recovery environment.
If you get a screen that says you need to use Recovery tools, you need another computer to create a recovery/installation media. You may also need to use Installation Media if the Windows Recovery environment says your password is incorrect.
How to Create Bootable USB Flash Drive to Install Windows 11
https://www.yourwindowsguide.com/2021/09/create...
Boot the computer from the USB Flash drive-Make sure you have disabled Secure boot/Fast boot in BIOS Settings and changed the boot order if required.
Afterwards, when you have successfully booted from the Installation media, click Repair your computer at the first screen after choosing the keyboard layout.
- Use Startup repair
The first option is to use Startup Repair, which automatically detects and fixes problems. Depending on the severity of the problem, it may or may not be successful.
- Uninstall Updates
The second step you can try is to uninstall the latest updates if Windows 10 fails to start after installing updates.
Choose Uninstall Updates.
Uninstall the update based on what was installed – a feature or quality update. Usually, the former is responsible.
- CHKDSK:
If uninstalling did not help and is unrelated, the next step is to try using a Disk Check.
Choose Command Prompt in the list of troubleshooting.
Get the Current Windows Installation drive letter, which is either C, D, or E, Type BCDEDIT, and Press Enter. Note the letter.
Enter the command given below:
chkdsk X: /f /r (Replace X with the Current Windows Install Letter)
When done, you will see the output and restart the PC to check.
- SFC/DISM Offline
Another try you can give to fix is SFC SCANNOW through Offboot switch. For this follow the steps below:
First, find the Windows Install drive letter using BCDEDIT command.
Then, try entering the following command:
sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows
After the scan completes, you will see the results.
You can also try using DISM: dism /image:C:\ /cleanup-image /revertpendingactions
- Reset this PC or clean install.
The last Step is a Reset. The catch with Reset is that all applications would be removed and files would be kept(you would be presented with the option to erase everything) alongside; a healthy Reset Image is required, which may be affected by corruption. If you use Installation media, you can do a clean install after rescuing your files.
