From my windows DVD, I've made an ISO image of it so I can copy it fully onto my USB(making it an ONLY install USB). The copying process took about 1-2 hours. I checked if the file were all there and it was. I then attempted to boot it from USB at the start of computer. I chose BOOT MENU > USB DEVICE, it takes about 1 minute then it says "Selected device is not available - press F11 to try again and F12 for setup" I think it was like this."
The files were all there, with the autorun.inf and all codes are good but how come it won't boot? Please help if you know solution.
