So, after some searching led me to the old grub vs. grub2 problem, I decided to just re-install openSUSE and let it find the UBUNTU partition. It did not find the partition and I had to use YAST to look for it. Note that when adding Ubuntu to the list, it asks me if I want to run the file checker. I did not. I checked the menu.lst afterwards and rebooted. After being sent to an ugly text screen (old grub-like menu) I was able to enter the new Ubuntu desktop.
Well, maybe I should try and understand grub2 again, but I cannot find anything about booting the system in the System Settings. I would like a nice screen and not have to go through two menus.
