booting existing windows from iso image or usb drive

i am looking for a way to boot an existing windows install from either an iso image (drive cloned to iso image (dmg)) or take the existing drive from a pc and boot from the existing drive in usb enclosure.

is there any way to do that and how?

 

did you ever figure this out? I'm researching the same topic.
