You could always download and use Resc-a-tux.

This is a live cd with a primary goal: Restoring grub/installing grub. It's a nice program which I used after windows just removed my grub without asking, and it worked like a charm.

Rescatux features:

Fixes GRUB and GRUB2

Regenerates Debian/Ubuntu grub menues

Check and fix filesystems

Fixes Windows MBR

Blank Windows passwords

Boot Info Script

Change Gnu/Linux password

Regenerate sudoers file

Extra tools:


Gparted 0.7
