Don't use it in the USB3 port.
I just wanted to say. THANK YOU!. I've been troubleshooting this for 5 hours (Did everything from new flashes of the image, downloaded a whole new image, played around with BIOS SATA settings...you name it).
Ofcourse, even though USB 3.0 is supposed to be backwards compatible to 2.0, this does not seem to be the case when trying to install windows through USB.
anyway, you are a savior!
