"Resetting this PC 11%" STUCK?

[Sawcyy]

Short story: My computer started acting unbearably slow so I did a reset that completely wipes the system, now it's stuck resetting.

Long story: I'd noticed my computer started having slow response times. Not only did start-up take a good 5-10 minutes, but my PC became painfully slow when tabbing out of a demanding game and sometimes I'm forced to switch off the PC using the power button as Task Manager wasn't even accessible due to the slowness.

This has led me to believe it was either a virus (unlikely as I scan daily and avoid downloading much at all) or hardware issue. So I'd decided to do a complete clean wipe using the Reset My PC option. Everything good until it hit 11%, and has been stuck at 11% for over 5 hours now. Really don't know what to do and what would be causing these issues.

Using Windows 10 upgraded from Windows 8

Don't think it's a virus, it could be but the more likely issue is that your Master Boot Record has been damaged or corrupted. Your MBR loads the OS for you, and if it's damaged it won't be able to do so.

You'll want to follow this guide to reset the MBR: http://pureinfotech.com/repair-master-boot-record-mbr-windows-10/

Be prepared that if it fails, you will need to do a clean install of the OS. Hopefully this is avoidable but with enough damage it's possible that the MBR is beyond repair.

Since we won't know what caused your MBR to be damaged, I'd recommend immidately backing up your system as soon as you can in case it happens again. You can use a disk imager like Macrium Reflect or a snapshot tool like Rollback Rx.
