When I try to add a partition to second HDD on my system, I can see the following output from /sbin/lilo:
Error: /dev/hdc1 and /dev/hda1 have duplicate volume IDs (serial numbers)
Fatal: Duplicated volume IDs must be resolved before installation can proceed.
Use the '-z' and '-M <dev>' switches to erase the conflicts.
lilo version 22.5.3 works fine if all partitions on second HDD are deleted (disk is empty), but fails when I add one partition of any size on second HDD, using '-z' and '-M' switches is useless. Google did not help. Any ideas?
