Centos 7 question - dev/centos/root does not exist
Newbie question.
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. Started file system check on dev/mapper/centos-root Warning could not boot Warning /dev/centos/root does not exist Warning /dev/centos/swap does not exist Warning dev/mapper/centos-root does not exist Starting Dracut emergency shell |

I thing I _maybe_ figured it out. I had a second backup hard drive in the PC, and I think I was booting off the wrong one...
Or maybe I was running off both if that is possible. When I booted off one hard drive, all the user accounts where there, but I had missing files. When I booted off the other backup hard drive, many user accounts were missing, but no files were missing. Thanks for the reply Steve! |
