You do not have an OSX Host, you have a Windows Host, and unfortunately OSX guests are only supported on Apple hardware (which you do not have). See: Mac OS X guest on a Windows Host.

In the really rare case (0.001%) that this is actually an Apple computer in which you have installed Windows, and you're trying to boot a legitimate OSX guest and not a Hackintosh, send me a PM and I'll remedy the situation. Be prepared to provide evidence in such a case.
