[plug] GRUB

[Shayne O'Neill]

Oh.

Lifesaver tip.

If you can boot into linux off a cd (for some reason knop never works with
this) but your redhat/debian/whatever disk *MAY* work. just get into the
installer then F1/F2/F3 etc till you find a # prompt.

mount your hard drive in there somewhere .

cd to the directory in question (with hard drive)

type chroot (directory where its mounted)

ie;-

chroot /dev/hda1

This will set your root to the hardrive root.

now all things being equal, and assuming lilo was correctly configured

just type lilo and it'll reflash your boot sector.

Now try *that* on ya windows box :)

Shayne.
