I've been trying to create a dual boot with OpenSUSE 11.1 and Ubuntu 9.04 and it has been giving me problems. I first install OpenSUSE which I believe formats the whole disk to ext3 by default, and that is what I did.
After OpenSUSE is finished installing, I install Ubuntu and try to do a specific partition, where I create an 8gb swap partition and the remaining space as my Ubuntu Partition. But I could not continue without create different mount point for each partition, which I make the Ubuntu Partition mount to (/), as I want Ubuntu as root, but keep the partition for OpenSUSE mount point the way it was, which was blank. I believe this is where the problem is, but I am uncertain.
After installing Ubuntu, it works completely fine, but when I reboot and log into OpenSuse, it's no longer bootable. I can not recall correctly, but the first error involved (/) which I believe is the root, and goes to the OpenSUSE login screen, which gives the same error when I attempt to login. I attempt to repair the problem with the OpenSuse CD, but the problem still lingers.
I attempt another reformat, but also did not end up successfully. I am attempting to do another reformat, but seeking advice before I do.
I've been thinking if I should make the SUSE parition mount point to (/boot), which would fix the problem.
