Mounting .disk files on Ubuntu

Sometimes we may be very unfortunate and we may not be in a situation to boot our Ubuntu. In such situations our only choice is to go for the file recovery.

This can be done easily in Ubuntu.

First use the Ubuntu live CD and boot your system.
Then locate the root.disk file. which is your Ubuntu's root directory.

If you have installed Ubuntu inside Windows
you may find this in C:\ubuntu\root.disk

in such situation you need to first mount your filesystem partition. This can be done by

Code:
sudo mkdir /win
sudo mount /dev/sda1 /win

always, replace "sda1" with the appropriate configuration, i.e. "sda2" or "sda3"...
(just remember: a=disk, 1=partition number)
and now you can find your partition in /win Directory.

Now you can mount your root.disk and this can be done by:
Code:
sudo mkdir /vdisk
sudo -o loop /win/ubuntu/disks/root.disk /vdisk

now your files in root.disk can be accessed through /vdisk

Root loging via GUI in Ubuntu

I'm writing this post since I have a problem of remembering this every time when I wanted to use it. I think this would also help you.

To get the root through GUI

1) You have to press

alt + F2

it will open dialog box called 'Run Application'

2) then you type

'gksudo nautilus' without quots

in the text field and then Ubuntu will ask for your Password.

3) type the password

then you will get the window with '/root'
where you have all admin rights

Note:
In this mode there won't be any warning when deleting or modifying files which will get you in to trouble even if you accidentally deleted or modified admin files. Therefore be careful and do not use this mode unless otherwise it's really needed.
