In BIOS I don't see it. But I use Windows 8.1 and 10 with 64 bit version that sees it when installing. First make a USB WITH WINDOWS using Rufus 2.4 or 2,6 version an choose Cpt UEFI compatible, then umplug all other hdd from motherboard. only 64 bit version of Windows support UEFI BOOT that recognize m.2 hdd
