After losing power, my machine rebooted to this error:

“error: no init found. Try passing init=bootarg”

Per similar threads on this site and others, I've tried booting from a CD and selecting "Try Ubuntu". Then open a terminal and typing:

sudo fsck-y /dev/sda1.

The response is:

Device or resource busy while trying to open /dev/sda1. Filesystem mounted or opened exclusively by another program?

This is on Ubuntu 10.10.

Any ideas on what I can try next?

Try sudo umount /dev/sda1 from the terminal in the LiveCD before running fsck – izx Jul 27 '12 at 22:43
umount: /dev/sda1: not mounted – glutz Jul 29 '12 at 17:57

Disk Utility from Live CD

  1. LiveCD or use a Live USB (your personal preference)
  2. Dash -> Disk Utility
  3. Mount Volume (try this first, if it mounts skip to #6 otherwise go to #4)
  4. Check FileSystem (this will run a check and repair anything it needs to)
  5. Mount Volume (second attempt, should work after Filesystem check if it didn't before)
  6. Close Disk Utility & Shutdown/Restart your computer.
  7. Remove the LiveCD (before shutdown) or the LiveUSB (after shutdown)
  8. Restart (may or may not go to GRUB menu, if it does choose the first option).

*Note - steps 4. & 5. are only for if the first Mount Volume attempt fails.

Here is a tutorial in the form of a detailed list of what steps to take to solve this listed by the original poster of the thread but improved by me.

This appears to work on every release of Ubuntu as I did it on 12.04

2.Boot from live usb and go to console fsck to fix filesystem
