This can mean a corrupted filesystem. Boot the live CD and use it to check your root partition.
The root partition is the one that contains the Ubuntu.

For example you can check the filesystem on partition /dev/sda1 with:

sudo fsck /dev/sda1

If you're not sure which partition to take, you can list them with:

sudo fdisk -l /dev/sda

where sda is your first disk, sdb second, etc...

If there is no physical damage to the disk or you didn't mess around with partitions, then mostly yes :P – danizmax Dec 21 '10 at 9:48
