Adding LFS to GRUB

dinolinux · 06-30-2005, 06:13 AM

Hello, everyone!

I have made an LFS system on hda4 which I have booted and used one or two times. But later I intalled Fedora Core 4 on hda2 and now I can't get GRUB to boot the LFS system. Do anyone know how to add an entry in grub.conf which will work???
My grub.conf:

Code:

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE:  You do not have a /boot partition.  This means that
#          all kernel and initrd paths are relative to /, eg.
#          root (hd0,1)
#          kernel /boot/vmlinuz-version ro root=/dev/hda2
#          initrd /boot/initrd-version.img
#boot=/dev/hda
default=0
timeout=5
splashimage=(hd0,1)/boot/grub/splash.xpm.gz
hiddenmenu
title Fedora Core (2.6.11-1.1369_FC4)
	root (hd0,1)
	kernel /boot/vmlinuz-2.6.11-1.1369_FC4 ro root=LABEL=/1 rhgb quiet
	initrd /boot/initrd-2.6.11-1.1369_FC4.img
title Windows XP
	rootnoverify (hd0,0)
	chainloader +1
title LFS
	root (hd0,3)
	kernel /media/lfs/boot/lfskernel-2.6.8.1

Do you need more information? Just ask!
Thanks a lot!

The kernel line for LFS needs to contain the full path of kernel as it is seen on the root filesystem of the LFS install, not the root filesystem of your Fedora install.

Try

kernel /boot/lfskernel-2.6.8.1

for LFS instead.

The correct entry should be:
title LFS
root (hd0,3)
kernel /boot/lfskernel-2.6.8.1
initrd /boot/initrd-2.6.8.1

Change the initrd file name if it is not correct. I haven't ever used LFS but I think that this should be correct.
The trick is the path. When you mount the lfs partition under /media/lfs , what you see in there is in fact the / tree in lfs

Hi!

There is no initrd in the LFS system. Should I create one with makeinitrd?

No, there is no need.
