Joey, Welcome to the board!!!!!
I have used LILO with my 120gig HD but only with dual Linux OS's
Does M'drake have GRUB? I don't know if any of the members use M'drake, don't seem to remember hearing much about it.
I would try other distros if I was you, Both Knoppix and Ubuntu have dual booted
for me and I don't know much about playing with LILO/GRUB.
Did everything else work?
Good luck, please keep us posted we all learn from other peoples problems!
