Comment 3 for bug 290140

I have found this to happen upgrading from Xubuntu 8.10 to Xubuntu Jaunty Jackalope. I have three hard drives installed, all PATA. I installed Xubuntu 8.10 to sdc, before installing jaunty to sdb. When I run the upgrade, all items upgrade as expected with no errors. When the system is restarted, the grub menu has not changed from before the upgrade. Selecting sdc to boot into from the menu does boot into Jaunty on sdc, but the grub menu is never updated. All installations have been told to install grub to the MBR of the first boot device.

I believe there is enough information to confirm this report.
