I'm upgrading from Vista SP1 (which was actually upgraded from XP over a year ago) to Windows 7 RTM (64-bit Ultimate to 64-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 Vista desktop, there's no error that I could see during install, I just a message indicating that it was reverting everything.

I tracked down the error logs and here's the log at I uploaded the error log (from C:\$WINDOWS.~BT\Sources\Panther) and uploaded onto Pastebin. Here is an excerpt:

It was suggested that I upgrade to SP2 before upgrading to Vista, but this made no difference. I since uninstalled SP2 since it was creating some problems with a piece of hardware.

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

Per Reuben's instruction, I found the install's dump and uploaded it here. (266 KB)
