I guess that's what I would call it... Basically I'm trying to find software similar to Virtual PC where I can take the hard drive out of another computer and boot it up on my main system in a sandbox type environment. Where I can have my main system running, but also have the other hard drive windows installation running in a window. If what I wrote is a little confusing, here is a picture of what I want to do. Except I want to use an existing windows installation and be able to edit/move etc. the users files. And is there even such a thing?
