Hi Andrea,
Corrupted system files after trying to rollback are one of the possible reasons why this issue is happening. Usually, restarting the computer should resolve the issue.
If the issue still persists even after restarting your computer, we recommend repairing Windows thru Advanced options. Follow the steps below:
- Press F8 while booting your computer to access System Recovery options.
- Click Troubleshoot.
- Select Command Prompt.
- Enter the following commands below, then press Enter after each command:
- chkdsk c: /f
- bootrec /fixmbr
- bootrec /fixboot
- bootrec /rebuildbcd
- bcdboot c:\windows /s c:
- Once done with the above commands, restart your computer and see if the problem is fixed.
Keep us in the loop with the result.
