Hi Jbc,
Out of curiousity, are you trying to upgrade Windows 7 from within Vista? or booting from the DVD? I upgraded from Vista to Windows 7 Beta from within(inplace upgrade) Vista and the installation went fine. (surprisingly lol). I left the laptop connected to the internet and at the beginning of the install I clicked "Get recommended updates" it then installed around 850 KB of info then rebooted and all was fine. just a idea :-)
here is a link that may help;

ps. clean install is the best way to go.... Windows Easy Transfer makes it easy to transfer user settings, docs, etc... quick to
but you will have to reinstall programs tho :-(
hope this helps...
