Having trouble dual-booting!

randell6564 · 11-01-2006, 12:50 PM

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)

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.
