Exactly, squirrellandmoose (cool name by the way). The complete system backup forces me to backup the XP drive with the Vista drive. The checkbox is checked and greyed out.
Lurkswithin, I think I'm going to do something like what you suggested. I'm going to use the Vista install disk to delete the XP partition. Recreate it as a 10gig disk - I'll use it for when I make cd or dvd images. This way I'll have the original disk letters. Then I can modify the Vista partition and expand it. Can also expand the E: drive. I'll do this as part of the Vista reinstall. I have a good complete file backup from yesterday, and an old Complete System Backup from New Years' Day also. I could try the Complete System Backup once the D: drive is too small to restore XP to. I'm assuming the Complete Sys. Backup doesn't repartition.....anyway....will probably get started soon.
