I'm upgrading from Windows 7 Enterprise (which was actually upgraded from Windows 7 Ultimate 3 months ago) back to Windows 7 Ultimate (32-bit Enterprise to 32-bit Ultimate). After 4 hours or so, the install fails with the message "This version of Windows could not be installed. Your previous version of Windows has been restored, and you can continue to use it." This error is back at my Enterprise desktop, there's no error that I could see during install, just a message indicating that it was reverting everything. Oh and my monitor wouldn't start after the PC rebooted again. After another reboot I could see it was reverting everything.
I tracked down the error logs and here's the files (from C:\$WINDOWS.~BT\Sources\Panther):

I know a fresh install is best, but I'm hoping to avoid that because I'd need a new hard drive.
