Dear Mr Farouk, > (which contain the boot commands) while the other failed to boot.

So the LILO searches for the root partition on the master disk. When there is no master disk it fails to read it. I think it should be enough to write a new MBR with an alternate lilo.conf, which tells the kernel to boot not the master disks root partition but the slave root partition. In other words search for the entry root=. It might say something like root=/dev/hda1. Change it to the slave disk, eg root=/dev/hdb1 (This example assumes master / in hda1 and slave / on hdb1). Probably lilo won't write to MBR and complains about hdb being not first disk. But you can fake this entry. I can't remember the rigth syntax. But I think a quick google search should solve this problem. Best wishes, Gernot Weber -- Gernot A.
