I am surprised - if you installed 64bit Windows - you have a VM!
Just go to www.virtualbox.org download it and install and - you have all of them, and simultaneously, and no dual boot mess!

You may test and chose many of them and you even can run 3, 4 even 5 systems in the same time. And more significantly - you may have desktop integration (all windows from both systems - host and guest at the same time). And share some directories between host and guests.

And start/stop/move virtual disks/DVD/USB sticks between them at any time.

And it is free (Oracle behind that) and easy.
