[TriLUG] Grub Error

[Deepan]

Hi All,
I deleted my windows partition using live CD. Now
my machine won't boot into linux. It stops at the
grub prompt with the error operating system not
found. How do I reinstall grub using live CD? Or
should I boot into my linux operating system with
root, kernel and initrd option in grub and then
install grub ?
