Ubuntu not booting due to filesystem error?

Has your Ubuntu system stopped booting after initiating a hard disk error checking? It isn't uncommon to see a disk error message after a forced shut down or crash or power loss.
When you try to boot Ubuntu, it will begin a disk check which will then give you an error message saying "mount of filesystem failed". The message will also say that a maintenance shell will be started. It will also inform you that Control+D will restart the maintenance shell. The system will then stop giving any message, leaving you with a blinking cursor. What to do next?
Run filesystem check manually
- Type fsck and press enter to begin a checking of the filesystem.
- It will then seek permission from you to fix the errors.
- Press "Y" or whatever it prompts to fix the errors.
- Once all errors have been fixed and the consistency of the filesystem restored, it will give a message saying filesystem was modified.
- Exit the maintenance shell by pressing Control+D or using exit command.
- Ubuntu will now start booting.

Ugh.
Thanks for the post, though - now I know for future reference!
