When install/upgrade, lilo fails. This is because setup has written a lilo.conf that tries to start up non-bootable partitions. Lilo fails, leaving lilo.conf to be edited manually, (the non-bootable parititions to be commented out) and lilo to be re-run. A problem for newcomers to Linux.
Need more information about where you installed Lilo and what partitition Lilo sets to boot.
Also a dump of what the lilo.conf file that is getting written contains would be helpful.
