Windows 10: Can’t do a system restore

I can’t turn on my computer because it keeps saying that I ran into an error and hast to search the computer to find one and then it says it’s going to diagnose it and then it brings me to a page saying that they couldn’t fix it and that I can either try and restart the computer or go to advanced options and when I went to advanced options, I was going to do a system restore, and it says I need a password, but when I got windows, I put that a pin code and now I can’t enter the password because my computer has a pin code another password

How to delete inactive System Image Restore Points in System Restore

Windows 10 64-bit.
When I click "show more restore points" in System Restore I see a bunch of old "system image restore points" that were deleted in past and do not correspond to any currently active restore points. Clicking any of these old restore points, I simply get an error message saying they could not be found, and to select another restore point instead.I would like to delete these restore points listings but have been unable to do so.
So far, I have tried steps mentioned below without any luck :

Disk Cleanup through (C Properties
Disable System Protection (OFF and ON) in System Protection for OS (C
Disk Space Usage to minimum (slider button all the way to the left then 'Delete all restore points for this drive'),
Delete all shown Restore points in CCleaner (the problem ones do not show here),
Reset Windows Backup to Default in Windows 10 with 'Reset_Windows_Backup.bat' utility.

Any suggestions highly welcome.
