I tried a little experiment, and took an SSD (formatted MBR) from a decommissioned PC and popped it into my MacPro5,1. Much to my surprise, it actually booted, installed some Windows vanilla drivers and found it to be (mostly) working. I then installed the Bootcamp drivers, and the new Windows SSD seemed fully functional (albeit at SATA II speeds.)
However, that leaves me with a problem. I think this picture explains it pretty well.
How do I tell which one is the new Windows SSD, and which is the old Windows hard drive? Can I just relabel one of them, or will that render the drive unbootable, or cause other issues? I have a graphics card which is not Mac EFI compatible, so I can't choose a volume at boot; I have to use the Startup Disk panel to choose which volume to boot from.
