I'll be brief. I want to understand why in the iMac 27 2013 you can install Windows in legacy mode, windows 7 and windows 10, and both systems perfectly see nvme disks and make it possible to install the system and boot from the nvme itself. While Mac Pro 4.1 5.1, when installing the system in legacy mode, to be more precise, Windows 7, after installing the nvme drivers, sees the disk and can copy data, but cannot boot. The installer says that I cannot boot from it because something is not included in the Bios.

As I understand it, in iMac 27 2013 the ACHI driver can load from the nvme disk, it is allowed. And in mac pro it is registered only with SATA bay 1-4?
