Bug Description
Binary package hint: grub
I have Maverick installed on /dev/sda1, and the GRUB configuration entry listed it as Ubuntu blah blah (on /dev/sda1). After yesterday's update, that entry is gone now, and only Natty's entry is available. The partition is still there though and is accessible from within Natty.

This was probably because your Maverick system's root filesystem wasn't cleanly unmounted. This is a known issue in os-prober. If you mount and unmount the Maverick filesystem from Natty then run 'sudo update-grub', that should restore it.
