It's not clear enough what you're trying to achieve... is it correct that you are trying to create a virtual machine based on your Boot Camp partition? What errors you receive? You could put here the output of diskutil list run from the Terminal (Applications/Utilities) and the screenshot of the system profiler on Serial-ATA tab (About this Mac -> More info -> Serial-ATA)
