I am trying to install Windows 10 on a new build (ASUS Z170-Deluxe). The SSD is a Samsung 950 Pro 512GB and is the only drive installed. Windows 10 is on a DVD. I get past the product key, the license, to the where do you want to install the OS? The only disk is my SSD. But it says "The selected disk has an MBR partition Table. On EFI systems, Windows can only be installed on GPT disks." So do I somehow convert my SSD to GPT (how?) or change something in the BIOS to allow the SSD to be recognized as GPT or at least non-MBR. The ASUS rep suggested connecting a normal HDD, loading the OS on that, then reformatting (to GPT) the SSD, then reloading the OS to the SSD. sounds like a pain. is there an easier way? oh my SSD is an M.2 form factor installed in the M.2 slot on the mobo.
