Can't Boot into Ubuntu after installing OpenSUSE 11.2

Hey I’ve been having trouble booting into Ubuntu 9.10 after installing OpenSUSE 11.2. When I installed it, the opensuse setup detected the partition ubuntu was installed on and added it to the grub menu. I also have windows vista and windows 7 installed and both boot up just fine from the opensuse grub boot menu. The ubuntu installation that i have was an upgrade from 9.04 so I am not using grub2 in that installation. So does anyone know what I can do to fix this problem?

Amd Phenom II X4 810 2.6ghz
4 gb ram
Ubuntu 9.10 64 bit
OpenSUSE 11.2 64 bit

When you installed openSUSE, did you create any more partitions before the Ubuntu partition or create a new logical partition? Such a change could require a modification of your Ubuntu grub menu setup. Perhaps you could post the grub error message that you receive when you try to load Ubuntu.

Thank You,

The entry that is placed in the openSUSE loader for Ubuntu doesn’t work, you should replace it with an entry like this:

#Don't change this comment - YaST2 identifier: Original name: none#
title      Ubuntu 9.04 booting via symlinks
root       (hd0,8)
kernel     /vmlinuz root=/dev/sda9 ro quiet splash
initrd     /initrd.img

Of course, adjust the partition [sda9 / hd(0,8)] to your situation.

I tried your solution and it works!! I even performed a Ubuntu kernel update without any problems. Thanks for the help!!
