Fixing No Init Found. Try Passing Init: Bootarg Error in Ubuntu

Today I encountered this error and I thought it was related to HDD issues. So I used fsck which is a command line tool to check and repair the linux filesystem. So I am writing this short how to so that it might be helpful for you as well.

The error encountered is something like below:

mount: mounting /dev on /root/dev failed: No such file or directory
mount: mounting /sys on /root/sys failed: No such file or directory
mount: mounting /proc on /root/proc failed: No such file or directory
Target file system doesn't have requested /sbin/init
No init found. Try passing init: bootarg

You need to boot your system with the Ubuntu live CD. After booting from live CD, open the terminal and then enter the following command:

sudo fsck /dev/sda1

Replace /dev/sda1 with your target filesystem partition and press enter. Whenever any fix or overwrite permissions are asked, press y. After finishing the repairing, reboot your system from hard disk. The system should boot without any error now.
I hope this helps you. :)
