Here are my suggestion
  • Attempt to boot single user mode by adding "-s" at the LILO or GRUB prompt. If you get a prompt (sometimes you will need to enter the root password), then fsck the ext2, ext3 partitions (more on this below) as indicated by the /etc/fstab file.
  • If that fails, boot your distribution CD in "rescue" mode. If your CD does not have a rescue mode, get Knoppix or Ubuntu. You can use these as rescue CDs. In this case, you will not have access to your /etc/fstab file since that file is unavailable. Get a list of ext2,ext3 partitions from running "fdisk" and fsck them. Also, the file /proc/partitions lists the know disks and partitions.
Run fsck with a command like "fsck -y /dev/hda2" (adjust hda2 to your partitions) on each ext2, ext3 partition.

However, your problem might be that the "root=/dev/<partition>" given with the boot line to LILO or GRUB might be incorrect. In that case, find out what your root partition is and add "root=/dev/<partition>" to the boot line.
