If you install Windows 7 or 8 on BC you can just upgrade afterwards if you want.
As for installing it should work just fine (But then again, Apple.) Just grab any serial key off of any website and install while offline so the installer can't check online to verify if the key is "legit". Then when inside Windows, use a loader or a KMS solution to activate your copy.
You could also maybe just download a pre-activated copy. But I prefer activating myself, I don't trust pre-activated ones.
