Hello, I'm aware that parallels can use an existing bootcamp'ed Windows installation as a Virtual Machine. I believe that the actual boot camp image can be used or a clone of it. If the actual boot camp image is used for the Parallels VM will Windows continue to work if the Mac is started with Windows via boot camp? I ask as the following video (at 13 minutes) suggests that the bootcamp image is upgraded to work with Parallels, my concern is that an "upgraded" bootcamp image would no longer work via bootcamp?
