assuming you're booting something ... even if its the lindows
trying to boot ..
if you have a boot floppy .. stick it in ..
if you wanna just erase what's in the mbr
root# fdisk /mbr
( now it wont boot anything from hard disk,
( so hopefully you have a fd or knoppix cd or any other
( install cd or floppy or hd
at the lilo or grub prompt, tell it to boot into "debian" (hda999)
lilo: root=/dev/hda999
root# grub-install /dev/hda
- or if its grub ... you have to tell grub the same thing to boot
a different partition
type "root=/dev/hda999" at the grub prompt
or hit "e" for edit, than add "root=/dev/hda999" at the
end of the line
hit "b" to boot it into debian
than
root# grub-install /dev/hda
if you wanna do things the harder way ... there's a dozen ways
to skin the cat
