Comment 19 for bug 45989

The nature of the bug is unclear form the original report. This is because it describes disks changing identifiers, which is perfectly normal and not a bug. If you still have issues with 10.04 or 10.10, please try describing them again so we can get the description updated. Specifically, what the exact grub-install command you run is, and what the results are. Attaching the output of this script would be helpful as well:
