I have shrinked the home partition of openSUSE and created an 30GB extended partition for Ubuntu
17GB root
12GB home
now i want to install Ubuntu, without losing openSUSE GRUB
or is there a way to get back grub from opensuse??
my current dual-boot system
openSUSE 11.4 (Desktop) on /dev/sda2 home /dev/sdb1
openSUSE 11.4 (Failsafe) on /dev/sda2 home /dev/sdb1
Microsoft Windows XP Home Edition SP3 on /dev/sda3
ubuntu would be on extended: /dev/sdb2: /dev/sdb5 root /dev/sdb6 home

Easiest way is install Ubuntu’s grub to Ubuntu’s root
partition (/dev/sdb5) boot sector.
Add to openSUSE Grub menu.list lines:
title Ubuntu
rootnoverify (hd1,4)
chainloader (hd1,4)+1

It seems that Ubuntu 11.04 installer did not written Grub boot code
to /dev/sdb5 boot sector, but dried to be too smart.
Kubuntu 10.04 and all other tested distros have worked quite right
with my way.

I did test installation to /dev/sdb1 using ubuntu-11.04-dvd-amd64.iso DVD.
At installation setup I selected boot from sdb1.
Code:
…
title Ubuntu 11.04
rootnoverify (hd1,0)
chainloader (hd1,0)+1
in openSUSE menu.lst worked OK. No difference compared to other distros.
So also ubuntu-11.04 installer works correctly.
