Can I change from Parallels to Bootcamp with same copy of Win7?

I installed Win 7 through Parallels to use as a virtual machine and it works fine.
However, I'd now like to have the option on occasion to use native Windows through Bootcamp. I understand that I can then incorporate this bootcamp back into parallels and use it as a VM on occasions I want.
But am I going to have problems with authenticating the version of Win 7 I have installed and authenticated. Will it be seen as Windows as being installed on a different machine if I now try and install it directly under boot camp?

 

It depends of the license you have. if it allows multiple installations it would work fine. In fact you can remove this virtual machine (backup all data you need) call Microsoft and tell you want to reinstall it to another hardware - I mean ask to deactivate previous installation. It should work.
