So, after many hours of searching threads from multiple sites, including here... I am clueless as to what I should try next. When trying to do a fresh install of windows off of a USB I continuously get this error message. I have tried hitting cancel and switching the ports as many people have suggested. I have tried putting my solid states drivers on the USB, as well as my motherboards drivers. My motherboard is the ASUS Strix Z270F , and therefore I do not have any USB 2.0 ports to use.. I have tried tweaking settings in my BIOS but I do not know it well enough to know exactly what everything does. At this point the only thing I can think of trying is going out and buying a new Windows disk because I'm becoming convinced it is because my motherboard only has USB 3.0 ports on it.. If anyone has any ideas it would be really appreciated as I don't want to go drop $100 on a new Windows installation disk.
