You also need to install GRUB (od lilo) on both disks, as I understand. Reallu I never understood how to do that from living hard disk, so I normally need to install GRUN from floppy the first time it starts. I normally do the following from a CD that I use to make istallations from grub --batch <<EOT device (hd0) $DEVICE1 root (hd0,0) setup --prefix=/grub (hd0,0) quit EOT grub --batch <<EOT device (hd1) $DEVICE2 root (hd1,0) setup --prefix=/grub (hd1,0) quit EOT but this often fails installing correctly. If I start from a floppy in which I have: title Install GRUB into (hd0,0) the first disk root (hd0,0) setup (hd0) title Install GRUB into (hd1,0) the second disk root (hd1,0) setup (hd1) It never fails. Hany clues?
