How to fix Boot drops (initramfs) prompts/busybox on Ubuntu

Have you ever experience a situation that you shutdown your Ubuntu OS and when trying to reboot the PC, the boot process drops to the (initramfs) prompts/busybox shell and you are stuck up on the prompt:

This error is due to corrupted files/ or partition.

To fixed this issue, the solution is just to scan fix the corrupted files. 

Simply run the fsck Command.

To fix this run any of the following command below and give Y if the console ask for fixing something.

(initramfs) fsck /dev/sda1

or

(initramfs) fsck /dev/sdaX

X specifies mounted disk part number.

If you don't want to continuously pressing 'y' every time it the console asks for a fix, you can also run the command with the -y option.

(initramfs) fsck /dev/sda1 -y

or

(initramfs) fsck /dev/sdaX -y

After the checking is done, rebooted the system.

(initramfs) reboot

That should fix the corrupted files and that's it, This will boot into the filesystem without any errors.
