Bug#311188: Debian edu messed up my Ubuntu system.

[Virginia Hicks]

My computer is running Ubuntu 7.10, Gutsy Gibbon.  After I installed Debian
Edu, I found that 1) my boot menu states that I am using Debian, and 2) my
program Ubuntu Tweak won't work because it is being told I run Debian and
not Ubuntu.  Please help.
