You mean the image? It's just a file. Copy and paste. It's very easy.
As a matter of fact, it's almost exactly like using Vmware Fusion or Parallels images, except that it HAS to be the same machine (almost always that is).
Yeah, make your new partition the same size as your old one was. Even 1GB smaller won't allow it. I did the special image, compressed I think. The second option. But yeah I had a 120GB partition cloned and compressed into 22GB Image or something, but upon restore I made a 119GB partition cuz I couldn't get the slider to 120 lol, then it wouldn't restore. So I had to delete the partition and remake it at 121GB and it restored fine.
You'll notice that if you have a Win7 partition, the boot load screen is back to Vista but no big deal. Also first boot you'll have to do the scandisk.
