virtualbox creates a virtual partition on your partition, this exists as a file in your c: or anywhere you installed vbox. it cant create a physucal partition, although it can use a physical on(not sure). if you are thinking of creating a physical partition, use windows disk management or any other partition manager. apart from that, as long as vbox creates a virtual partition or links to one, you can install any of the supported OSs and boot in virtualbox, not outside.
