Hey there. I had to install a forced update on my 64bit Windows 8.1 HP Pavillion PC. When the update finished, the PC no longer boots up. I can get to the HP logo before everything stops working, and its an endless spinning icon. I tried system restoring and it did not work, tried command prompt stuff and it didn't work either. The update just came out and ive seen many people online with now broken computers due to it. People have figured out that deleting 'FNTCACHE.DAT' in sys32 folder fixes it, but when I try to, it says the file doesnt exist. (CMD).
Refresh PC would probably work except that when I attempt to run it, it says my recovery drive is locked and cannot be used unless I unlock it. HP installs recovery files on a separate drive (D:) and that's how you refresh/reset. I'm not sure if there is a CMD method of bypassing or unlocking the drive so I can refresh my PC, or if I'm just out of luck. I absolutely DO NOT want to reformat as i will lose countless files of importance that were not backed up, so any potential fix to this would be lovely. Its worth noting that this mandatory update is brand new, not even a week old and MS has acknowledged the problem.
Any advice or ideas? I'm running out of patience and methods at this point.
