I am looking for recovering my data using any tool, and I can re-install Ubuntu later on.

Thanks for your reply

A couple of ways that others have posted. Can you then mount it?

sudo mkdir /media/win
sudo mount /dev/sda2 /media/win
sudo fsck /media/win/ubuntu/disks/root.disk
Then check if you can mount it & read it:
sudo mount -o loop /media/win/ubuntu/disks/root.disk /mnt

Run chkdsk /f from windows before you try anything else.

See 'missing root disk' links above.
