Comment 36 for bug 185878

Dave's previous attempt (comments 34/35) broke because he had / on /dev/sda6 but was attempting to install to the nonexistent (hd0,0) (a.k.a. /dev/sda1). I then had an attempt that failed due to the problem fixed in http://bazaar.launchpad.net/~ubuntu-core-dev/grub-installer/ubuntu/revision/833 (not a regression; but note that you need to explicitly mark a partition as bootable in the partitioner when performing this test). Dave then had an attempt that failed because he had a former installation on the same disk which of course (intentionally) didn't have its boot loader removed from the MBR.

Once we got past all those roadblocks, though, both of us appear to have working installations now.
