Centos 7 question - dev/centos/root does not exist
Having trouble booting Centos 7 on a Dell PC and I wanted to ask why.
Everything the other day was fine but I wanted to use the computer to run spinrite on another drive, so I changed the BIOS from "Raid Autodetect/AHCI" to "Legacy".
The next day I forgot to change the BIOS setting back, and booted Centos 7 fine, but I noticed files were missing.
So when I change the BIOS back to "Raid Autodetect/AHCI" I can't boot and get this error below.
I wanted to ask if changing the BIOS settings to "Legacy" and not swithcing back to AHCI before rebooting again, cause the boot error below, and if I need to reformat and start fresh... or if there is a fix.
