Recovering MBR

[James Marcinek]

Hello everyone,

I have a duel boot system with Fedora 2 and Windows XP installed. Now
forgive me ahead of time.  I was using GRUB as my bootloader and
was running fine until last night when I upgraded my Windows XP to XP
pro. The Windows XP pro upgrade must have overwritten my MBR. How
should I go about putting GRUB back into play. I would like to keep my
existing linux install if possible.

Thanks,

James
