The instructions I've used a few times when nasty operating
systems have hijacked my MBR go like this:

Boot off fedora dvd.

Type linux rescue, answer all the questions, might as well skip
mounting any partitions.

grub
root (hd0,0)
setup (hd0)
quit
exit

(Of course, that assumes hd0 is your boot disk and the very 1st
partition on it is the boot partition - usually the case, but doesn't
have to be).
