I’m not quite sure what you are doing there. I routinely use USBs. I typically use “dd_rescue” to copy the iso file to the USB. I have also used imagewriter (from linux, not Windows). Both have worked. I have also seen reports of people failing when using “unetbootin”, though some people succeed. The script “live-fat-stick” also seems to work with opensuse live images (use google to locate it). My suggestion would be to use “live-fat-stick” or “dd_rescue” (if available on your current linux system).
ive ran it as Administrator and still getting the same problem, ill give that ImageUSB a try as ive just tried to make a bootable USB using a terminal but when i boot from it im stuck on a blinking _ in the top left corner
