Where do you get the error? Can you get into windows? Does safe mode work? What did you use to clone the drive? What hardware specs do you have - scsi card?
MAybe its a thing with Windows 7 - I doubt the software is certified for it yet?
Last time I had to clone something (a few years ago) Norton ghost did a pretty good job.
If you can somehow get into windows, uninstall any apps like Alcohol, Nero, Daemon Tools. Otherwise if you can't get into windows, just ignore what I said
