Have several machines to upgrade. All were upgraded from Win2K to Vista Business, each of which went off very well (yeah, it was a total reinstall of a new OS and loading the programs fresh, but that's OK) . Trying to upgrade to 7 gets error that it's unable to install Windows 7 because of an "incompatible NTFS version." I've tried it on three identical machines with the same error. If I run the Windows 7 Upgrade Advisor it says that everything's fine and there's no problems.
If I boot from the CD, there's probably going to be some data or settings losses I really don't want to have to do. Any suggestions?
