Windows 7 has completely broke after turning off during malware bytes reboot

[Jackstrh]

Recently malware bytes automatically scanned and rebooted my pc. It did not ask if I wanted to do this, it just did it with a couple of seconds warning. During the reboot, my pc was powered off.

The next day my pc wouldn't boot windows 7 fully. It would load up to the password screen, around 20 seconds later my pc would reboot. This then becomes a cycle of on, off, on, off. Whenever my pic is in bios for example, it doesn't do this, it only does it when booting windows 7.

Occasionally during this cycle, it will automatically start a disk check, but it says autodsk cannot complete because of a recently installed package or somethin like that.

I tried booting all safe mode options, all of them take me to a black screen.

I tried booting with last successful settings, same cycle result

Multiple Windows repairs did nothing.

I then used my windows usb. Start up repair didn't work, system restore gives the error (0x80071a91) and I also tried some commands such as bootrec which also did nothing.

I also tried Windows memory diagnostic and no problems were found.

Any help would be much appreciated.

Is it possible that some critical file was infected? If so, your only choice is a windows install. If you haven't made backups of your data, then purchase a new disk, install onto that disk and use your existing disk as a data disk. Once you have a functional PC you should be able to copy your data off the first disk.
