I don't have a system on which i'm able+willing to try it out, but if your goal is to revert it to an MS-Windows only partition table (whether temporary or permanent), I think something like the following sequence would work. I'd back up before touching a partition table (even if doing something that i would believe is known to always work).
1. Boot with Ubuntu live CD in CD-ROM 2. Boot from first hard drive (instead of live CD session or installer), when the Ubuntu CD asks you. 3. Run command shell box (cmd.exe) 4. fdisk /mbr (fdisk is the one to treat with great respect) Randall
