I am migrating from my old Windows 7 computer to a new Windows 10 computer. I got a 4TB SSD for this purpose (seperate from the OS drive). I installed the drive in Windows 7, formatted it with GPT, and copied my files over. I removed the drive, installed it in my Windows 10 box, and it isn't appearing correctly in disk management, its showing as an MBR drive with a "GPT Protected Partition". Moving the drive back to Windows 7 it works fine. Any ideas on why Windows 10 wouldn't see this as a GPT drive? I've gone through most of the BIOS settings and the problem doesn't appear to be there.
