Is your drive encrypted? Is the drive formatted with MBR and the new PC has CSM disabled in UEFI? (In which case you really want a new install with GPT)

i restored the uefi to default so csm is off and it was working before but idk what i did but after i reset it then it bsod but i can’t figure out what i did but i do not know what mbr is. i just tried resetting the os on my other pc see if maybe reseting windows and putting the nvme back in would work but it still shows the same bsod at this point i think it might be the mother board where the nvme is going but idk why it worked before then all the sudden it stopped working without me touching it
