[NTLUG:Discuss] Grub .94

[Rob Apodaca]

Assuming you want the mbr installed into /dev/hda1 and your kernel image
is located at /boot/kernel-2.X.X

create a valid grub.conf in /boot/grub/grub.conf

Here is a minimal one:

default 0
timeout 30
title=Linux
root (hd0,0)
kernel /kernel-2.X.X root=/dev/hda1


Then, there are two ways to get grub installed to MBR:

FIRST WAY: Use grub shell
$ grub
grub> root (hd0,0)
grub> setup (hd0)
grub> quit
* Note, type commands above exactly as shown...
"root (hd0,0)"
NOT "root(hd0,0)"


SECOND WAY: Use grub-install
grub-install --root-directory=/boot /dev/hda

I really like grub but it is a little tricky to get the hang of. Hope
this helped.

Cheers,
-Rob
