I know about this. I actually can enable secure boot and fast boot with windows 10 uefi. My question is why it says "UEFI:OCZ...." and not "Windows Boot Manager" in boot option, like most photos from gigabyte motherboards online. Is created that way, is it a visual bug or something similar, or it has something to do with the instalation of Windows 10. When i first installed them i had a GPU without uefi bios, but i now have uefi vbios.
