Saw a video on youtube saying enabling rebar in bios significantly boosts performance.. was bored and followed a guide online to enable it in bios.

Motherboard is TUF Gaming B550-PLUS. Guide said to ‘Enable “Above 4G Decoding” -> Enable “Re-Size BAR Support” in the Advanced tab’ and to ‘disable “Launch CSM” in the Boot tab.’

Rebooted and was sent to windows automatic repair. Tried following some guides online, most claim the fix is to make sure your boot drive is on a GPT partition and if not to convert it from an MBR to GPT. The issue is my windows os is installed on a GPT partition already.

I’ve already tried and messing with variations of the BIOS settings I initially tweaked, toggling between CSM on and off etc.

Tried to boot in safe mode, rolling back to restore points (my drive is too full to do so anyway), disabling 4G decoding etc.. no dice.

I can only boot into BIOS or windows automatic repair at the moment. Just want to get windows back up without data loss.

Any help is greatly appreciated.
