MacOS Sierra Disk Utility doesn't show my installed drives

So I wanted to have macOS on my PC, but I don't have a MAC so I downloaded a pre-made RAW file, which I had to write on an USB. A saw it on a YouTube video and it seemed legit. I have an Asus Maximus VII Ranger, a GTX 760 and an i7-7490. I set the recommended settings in BIOS. My sata is set to AHCI. I can sucessfully boot into the Installation but when I have to choose the Drives it only shows the USB stick. I have 2 SSD-s and 2 HDD-s. On the main SSD I have a WIN 10 the other one is empty. I tried the installation process with all my disks removed expect the SSD which I'am willing to install the OS on. Please help me!
