I can't be much help at all unless my background (several years back - memory may have aged out and been permanently "swapped") using LILO for some stuff might give clues. I continue only in the hope that the answer might come to you while awaiting knowledgeable participation. Is it correct that the raid must come into play after initial boot *if* one is to be able to boot on the remaining disk after primary fails? My thinking is that if raid is in play when grub is installed, does it mess up where things are put? If not, does it mess up when there's a failure (raid 0,....5... I guess would affect that). Is it boot from boot partition, install grub, copy to second disk. Is grub (stage 1?) installed in *partition* or in mbr? If in partition, partition must be made active? Both drives? If raid is active when you try to write initial loader to mbr/partition, does it mess it up? Can you get to where you can boot one disk w/o raid active? It would be aggravating if it was nothing raid related, but some hardware/user/software error making you think it was your raid doing it to you. > > Kai > HTH -- Bill
