I think the default setup for Debian is to use a fairly simple MBR, which lets the user press any of "1234" to boot to /dev/hda[1234], repsectively. If you had Some Other OS installed on /dev/hda1 and LILO on /dev/hda2, you could use the MBR to pick which one and avoid the LILO configuration. Given grub, though, there's no reason to run LILO. My system uses grub to boot to one of a couple of Linux kernels or Win98, and I haven't touched LILO here since I installed the machine (a couple of months ago). I don't think grub is any harder to set up for this case; it's just different. (Also, with grub, you don't need to do anything special when you install a new kernel. With kernel-package, though, this is less of an issue, since it's harder to forget to run lilo.) TB> Please could someone explain whether it is safe to install LILO in the TB> MBR? Alternatively, what *can* I put in the MBR to replace the TB> current installation of grub (whose configuration is sitting in the TB> Mandrake partition)? You could: -- Install LILO in the MBR. There's nothing actually wrong with doing that. -- Install the Debian MBR (from the mbr package) in the MBR. -- Reinstall grub in the MBR, either tweaking the grub configuration you have in Mandrake to boot Debian, too, or starting over with configuration in Debian. If you've got Debian on /dev/hda4, say, you'd add title Debian GNU/Linux root (hd0,3) kernel /boot/vmlinuz-2.2.16 root=/dev/hda4 to your Grub menu.lst. The (hd0,3) specifies the OS root partition; hd0 is the first hard disk (probably hda under Linux) and 3 is the fourth partition (/dev/hda4). -- David Maze [EMAIL PROTECTED] http://www.mit.edu/~dmaze/ "Theoretical politics is interesting.
