I have done everything in the guide to get the USB drive prepared. I even tried this as UEFI and Legacy, and for Legacy I followed the steps in Post #2. When I select to boot from the USB in both modes I receive the message, "Selected boot device failed. Press and key to reboot the system."

 

Again I have tried this in UEFI and Legacy modes with the same error on both methods. I appreciate any and all help!
