I just tried updating to 13.04 from 12.10. When I restarted, it went to Grub even though there's no other OS on the computer. I clicked on Ubuntu to finish booting and I got a terminal with the error message:
General error mounting filesystems. A maintenance shell will now be started. CONTROL-D will terminate this shell and reboot the system. root@mycomputer:~#
Reboot brings me back to the exact same place.
The only other options on Grub are Advanced options for Ubuntu and a couple of memory test options. I ran one of them and it came out fine.
I have no idea what to do next. Please advise.
Per request, here is the contents of /etc/fstab:
# /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed.
