The truth is that it is possible but requires more advanced knowledge. But please follow Parallels rep advice first.
The procedure to clone a an existing installation of Windows to another hardware environment (that's what you are after, technically) is not a straightforward procedure and it's best to try other options first. The procedure is very much the same as cloning from one physical machine to another, and there are programs and tutorials on the web for that, requires some more advanced knowledge to understand how to adapt it to a VM.
