Since this thread now seems to be "barking up a *new* tree" I will chip
in here and add that I had MBR problems before that wouldn't allow lilo
to be replaced by grub, despite repartitioning and reformatting the
drive.  A grub FAQ recommended reformatting the MBR to clean the slate
by booting with a floppy and executing "fdisk /mbr" at the prompt.  That
may do the trick if that area of your disk is the root (pun) cause of
the problem.
