I switched over to a new pc and brought my hard drive from the old to new pc. Im getting an error saying that my boot drive is inaccessible; however, when I put my hard drive back into my old pc I didn't have an error. I checked to see if the cables where in the right places and plugged into the power supply. I have tried to boot from sata, windows boot manager, and uefi. If anyone has a fix please let me know!
