Trying to chainboot Slackware from Grub2

Dear all,
I've made a mini installation of slackware64-13.1 onto my friend's computer. He already has Ubuntu and Windows partitions that are being handled by GRUB2. I thought the best thing to do would be to have lilo installed to the partition root (on /dev/sda3) and let grub2 chainboot. I've been reading about adding custom entries to the grub menu and things look like they're working but then I reboot and there's no Slackware option.

Currently I've got this file in /etc/grub.d/41_slack. It is executable.

Code:

#!/bin/sh -e

echo "Adding Slackware"

cat << EOF

menuentry "Slackware" {

set root=(hd0,3)

chainloader (hd0,3)+1

}

EOF

When I run "sudo update-grub" this is the output

Code:

lewi@benny:~$ sudo update-grub

Generating grub.cfg ...

Found linux image: /boot/vmlinuz-2.6.32-22-generic

Found initrd image: /boot/initrd.img-2.6.32-22-generic

Found memtest86+ image: /boot/memtest86+.bin

Found Microsoft Windows XP Home Edition on /dev/sda1

Found Slackware Linux (Slackware 13.1.0) on /dev/sda3

done

So it has found the slackware partition (not because of my menu entry though?) but when I reboot there's no menu entry there.

Any ideas?

I am using GRUB2 because I can compile it on a 64 bit system & I want grub, not lilo, but I will admit that the automagic menu maker for GRUB2 completely underwhelms me. I edit /boot/grub/grub.cfg by hand just like I did the legacy grub configuration file. It works a treat, but someday I will teach myself how to use update-grub.
Regards,
Bill

Thanks but I would much prefer to be able to use grub2 without having to manually mess around with grub.cfg. Does anyone know if I'm actually doing anything wrong or is there a better way of getting the three systems booting? I'm much more familiar with lilo so I might just try getting it all to work with that.

It seems to be working now, I think it was something to do with having some grub legacy stuff lying around. Will mark as solved.
