Installing Microsoft Windows VM on OS X
Do I understand correctly that you wish to transfer an existing Windows machine configuration, with all its apps and data, to your Mac? If so, and Boot Camp is a no-no, then you need something like Parallels Desktop 11, which will enable you to run Windows 7, 8 or 10 alongside OS X and switch from one to the other very easily. Indeed, if you have sufficient storage capacity, two or more Windows virtual machines can be set up.  I have 7 and 10 virtual machines on my MacBook Pro. Installing Windows is a breeze, but transferring the existing machine configuration will be an unavoidable chore; I don't know of any shortcuts.
