Sure...just rerun lilo after booting from the boot disk.  Or make a backup of the
MBR:

dd if=/dev/hda of=xyz.mbr bs=512 count=1

You can always restore it:

dd if=xyz.mbr if=/dev/hda bs=512 count=1

Always a good idea to back up the MBR, especially before using fdisk.  In the
pre-2.2.12 kernels, where there is a problem with fdisk creating partitions > 33G,
fdisk fails rather ungracefully by corrupting the MBR.
