Having trouble dual-booting!


Hey Folks!
I have two Ide HD's. hda1 master which houses Ubuntu 6.06, and hdb1 slave which is home to the newly released xfld of which was installed last night.

I expected to get a dual-boot option after xfld was installed, but to no avail!
Here is my /boot/grub/device.map
Quote:
(hd0) /dev/hda
(hd1) /dev/hdb
Here is my /boot/grub/menu.lst for Dapper Drake (hda1)
Quote:
# menu.lst - See: grub(8), info grub, update-grub(8)
# grub-install(8), grub-floppy(8),
# grub-md5-crypt, /usr/share/doc/grub
# and /usr/share/doc/grub-doc/.

## default num
# Set the default entry to the entry number NUM. Numbering starts from 0, and
# the entry number 0 is the default if the command is not used.
#
# You can specify 'saved' instead of a number. In this case, the default entry
# is the entry saved with the command 'savedefault'.
# WARNING: If you are using dmraid do not change this entry to 'saved' or your
# array will desync and will not let you boot your system.
default 0

## timeout sec
# Set a timeout, in SEC seconds, before automatically booting the default entry
# (normally the first entry defined).
timeout 3

## hiddenmenu
# Hides the menu by default (press ESC to see the menu)

I am missing something, I know! Any ideas on how I can get my dual-boot?
Thanks!

Well, neither of them have any references to xfld or (hd1,0), which is where xfld lives. Typically, here's what I do when multibooting:

1) install the first linux with grub going in the Master Boot Record (MBR) of the first hard drive.
2) install the second linux, but install grub to the root partition (in your case, /dev/hdb1).
3) add a section to the first /boot/grub/menu.lst like this
Code:
title xfld
root (hd1,0)
chainloader +1
boot
What this does is use the first grub to boot the second grub. The second grub will boot xfld.

From your 2 menu.lst files (which by the way, look the same to me, and they shouldn't), it looks like you're booting into Ubuntu okay. So boot into Ubuntu, and then do the following:
Code:
mkdir /mnt/temp
mount /dev/hdb1 /mnt/temp
chroot /mnt/temp
grub-install /dev/hdb1
Then add the snippet above to the Ubuntu menu.lst and chainload xfld.
