Just out of curiorsity does Windows run inside VirtualBox or does VirtualBox run inside Windows? Or, put another way, does one install VirtualBox on a blank hard disk and then install Windows and Linux etc?
Also, out of curiosity, doesn't the use of VirtualBox (or equivalent) use up a significant amount of the PC's performance before any OS gets a look in?
I have been thinking about something like this but I have never tried it.
