Cause
Resolution
- On the single user shell, run the commands below to edit /etc/fstab:
mount -o rw, remount / vim /etc/fstab
- Delete the parts of the fstab that look like what is in bold below (that is, /dev/disk/by-id/scsi-14d5346542020202000000000000000000000000000000000-part1):
... tmpfs /run tmpfs noauto 0 0 /dev/disk/by-id/scsi-14d5346542020202000000000000000000000000000000000-part1 / ext3 defaults 1 1 /dev/sdb1 swap swap defaults 0 0
- Replace the text removed in step 2 with the text in bold below (that is, /dev/sda1):
... tmpfs /run tmpfs noauto 0 0 /dev/sda1 / ext3 defaults 1 1 /dev/sdb1 swap swap defaults 0 0
- Press Esc then :wq! to save changes.
- Run the following command to edit the /boot/grub/menu.lst:
vim /boot/grub/menu.lst
- Delete the parts of the menu.lst that look like the bold text below (for example, /dev/disk/by-id/scsi-14d5346542020202000000000000000000000000000000000-part1 and /dev/disk/by-id/scsi-14d5346542020202000000000000000000000000000000000):
