Repairing Your Grub Bootloader
Last week a friend of mind tried to install Windows XP on his system after installing Ubuntu, and of course the result was that he lost his bootloader.
Don’t panic though, just boot off your Live CD and open up a Terminal window.
Then execute these commands:
sudo grub
root (hd0,0)
setup (hd0)
Close out the Terminal and reboot, and you’re good to go! Just don’t forget to eject your Live CD. This should apply to any Linux distro that uses the Grub bootloader.
