Windows 7 professional VHD

[Pietia]

Hi I'm using latest Beta and the option to use windows 7 professional as VHD option is grey out I can only use windows 7 enterprise for VHD for which I don't have a valid license key.
Any way to use professional version with VHD on?

Windows 7 professional doesn’t support VHD boot, this is microsoft's limit. For more information, please visit:
