Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

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

Welcome to Ask Ubuntu! Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. – fossfreedom Jul 29 '12 at 18:47

Here is a tutorial in the form of a detailed list of what steps to take to solve this problem...as 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
