[Bug 878834] [NEW] Ubuntu 11.10 installer uses incorrect partition in grub.conf

[Launchpad Bug Tracker]

I have a MacPro with two hard disks: the first disk with OS X and the
second with Ubuntu. I upgraded the Ubuntu installation from version
11.04 to 11.10 and the upgrade was successful, but when rebooting it put
the computer into Grub Rescue.

When I installed Grub, I installed it to the Ubuntu hard disk (/dev/sdb)
and the installer created grub.conf to boot from (hd1,gpt2). Whilst this
seems correct, Grub sees things differently. Grub seems to need the
config file setting to say (hd0,gpt2) to work correctly. Changing the
grub.conf file fixed the issue and allowed the system to boot correctly.

I'm not sure whether this is a bug in Grub or the Ubuntu Installer. I
can provide additional logs, if you let me know which ones you need.
