2.4 On Boot Loader Installation tab I checked "Boot from Root Partirion" and unchecked everything else
2.5 On Boot Loader Options I checked "Write generic Boot Code to MBR" and unchecked everything else
It looks like you have created a conflict of some kind here.
In 2.4, you elect to boot from the root partition (first stage of bootloader written to the boot sector of the root partition). In 2.5, you choose to write code to the MBR (the boot sector of the hard drive).
These are not the same. You need to make them consistent. Set both to write bootloader to the root partition.
Note: this will not add Suse to the grub menu that you see on boot. You will need to boot into Kubuntu and run update-grub as root. That will search the hard drive for bootable OSs and add Suse to the grub menu.
If Kubuntu is not bootable at present, boot from your Kubuntu installation cd, choose the option to boot from the installed Kubuntu. When booted from the hard drive, run update-grub.
