I'm currently running Mandrake8, booting (lilo) from hda3, this has worked fine.
Now I installed Mandrake9, but installed lilo in mbr - want to hold them apart since I'm not sure which version I'll keep.
Booting from mbr is no problem, but the strange thing is I can't change it! Using fdisk I mark hda3 as active, not hda1 - still Mandrake 9's lilo menu appears.
Does lilo in mbr mean you can't boot from any other partition? This would be crazy - you can definitely have bootloaders in mbr but boot from other (primary) partitions.
