Can't chainloader +1 Kubuntu 8.10

[Apollo9]

I just installed Kubuntu 8.10 and I'm trying to chainloader +1 it. I have Linux Mint installed on my boot drive (my first drive) and Kubuntu is installed on my second drive.

When I try to chainloader +1 Kubuntu I get this error message.
Error 13: invalid or unsupported executable format

When I installed Kubuntu I put GRUB on hd1,0 instead of the MBR. I installed Kubuntu over OpenSUSE 11 (I formatted the partitions when I installed Kubuntu) and chainloader +1 worked fine with OpenSUSE1.

Is there something special I need to do with Kubuntu's menu.lst or fstab? Thanks for any help.

Re: Can't chainloader +1 Kubuntu 8.10

and specifically, for chainloader to work, you MUST have GRUB installed to the boot sector of Kubuntu!!! (i.e., not to the MBR of the 2nd HD, although it doesn't hurt to do so)

So, if Kubuntu is on, say (hd1,0) ( = the second hard drive, the first partition),
you can install GRUB to the boot sector ( = the first sector) of (hd1,0)) using these GRUB commands:

from a Live CD
at Konsole
sudo grub
grub> root (hd1,0)
grub> setup (hd1,0)
grub> quit
$exit

then, in any menu.lst, you can boot that Kubuntu using this boot stanza:

title Kubuntu whatever
chainloader (hd1,0)+1

(if you are at a grub> prompt doing it, you also need the boot command:
grub> boot )

Installing GRUB, the link dibl gave you:

Re: Can't chainloader +1 Kubuntu 8.10

Dibl and Qqmike thanks for the help. I read the links but I couldn't get anything to work.

title Kubuntu 8.10 KDE 4
root (hd1,0)
chainloader +1

That didn't work.

This is the menu.lst Kubuntu created on hd1,0

I copied the entries for the Kubuntu kernel to the menu.lst on the MBR of hd0,0. I looked at the entries for Linux Mint in the menu.lst and edited the entries for Kubuntu to make them more like the entries for Linux Mint.

This is the entry for Kubuntu from the menu.lst on hd1,0.
title Ubuntu 8.10, kernel 2.6.27-9-generic
uuid 4725f4b6-7020-44dd-8f07-3ecf6ba3bd6c

initrd /boot/initrd.img-2.6.27-9-generic
quiet

This is the entry from the Linux Mint menu.lst on the MBR of hd0,0.
title Linux Mint 5 KDE CE, kernel 2.6.24-19-generic
root (hd0,0)
kernel /boot/vmlinuz-2.6.24-19-generic root=/dev/sda1 ro quiet splash
initrd /boot/initrd.img-2.6.24-19-generic

This is the edited entry for Kubuntu in the menu.lst on hd0,0.
title Ubuntu 8.10, kernel 2.6.27-7-generic (on /dev/sdb1)
root (hd1,0)
kernel /boot/vmlinuz-2.6.27-7-generic root=UUID=4725f4b6-7020-44dd-8f07-3ecf6ba3bd6c ro single
initrd /boot/initrd.img-2.6.27-7-generic

boot

So, now I can boot Kubuntu from the GRUB on hd0,0 without chainloading. The chainloading didn't work before so I gave up on that. When I tried to boot Kubuntu before editing the entry for it I got an Error 13 message.

Re: Can't chainloader +1 Kubuntu 8.10

I dunno, something looks odd about your menu list entries for Kubuntu. Here's what the one that I boot looks like:

title Ubuntu 8.10, kernel 2.6.27-7-generic
root (hd1,0)
kernel /boot/vmlinuz-2.6.27-7-generic root=UUID=4ee99d57-a4e3-4381-a900-7a57cfa9eea2 ro xforcevesa quiet splash
initrd /boot/initrd.img-2.6.27-7-generic

Is the line

uuid 4725f4b6-7020-44dd-8f07-3ecf6ba3bd6c

supposed to provide the same input as the line

root (hd1,0)

?

Also, the "groot=" line in /boot/grub/menu.lst should be the same partition as the default kernel that you want to boot. So, in mine it reads like this:

# groot=(hd1,0)

But, if it's working for you, don't change it!
