I got a question here: I have Windows Vista installed on the primary hard drive using the Asus slic 2.0 bios and Asus certifcate for my P5B. I"m planning to install Windows 7 on the secondary hard drive on the same system. I will be using the P5B HP slic 2.1 Bios & HP certificate to activate 7. Since the P5B is using the HP slic 2.1, if I booted the primary drive with Vista, do I need to remove the Asus certicate and implement the HP certificate for Vista? Thanks for any insights into this.
