I have a Windows 10 machine with two hard drives, both containing bootable and activated copies of Windows 7 and Windows 10. I want to be able to dual-boot from either drive, but I’m not sure how to set it up. I’ve searched for answers, but most of them involve installing a new Windows partition, which I want to avoid since I already have two working drives.

So, my questions are: How can I set up a dual-boot configuration between the two drives, and will I run into any issues with “Authentic Windows” validation when I boot from the old Windows 7 drive?
