Comment 2 for bug 426863

I just this afternoon rolled back from karmic to jaunty because grub in karmic could not find my other linux partitions, let alone osx and bsd.

It is a fairly unpleasant workaround to wipe the hd and give karmic another try.

In a week or two when I go back to multiboot, I can give partition data. But for now grub in the default installation process in karmic does not find the other partitions.
