So I currently have a 240GB Kingston 3K SSD on Computer A. I also have a HDD installed on Computer A. They both have Win7 installed on them. When I boot I'm given a choice which SSD/HDD to boot from. (AHCI active, etc) Everything works. Problem: I put SSD from Computer A to new computer, Computer B, and get "please select proper boot device and press any key" when I try to boot. The SSD is recognized in the BIOS and is the only boot device in the new computer! How do I get it to boot?!
