I was able to boot that specific image on a couple of different USB devices and two different machines with no issues. Your problem seems to be related to bios and/or boot order. If you have a way to select your boot device, either by pressing the escape key or a function key (mine is f8), try to select it from the boot menu. Note that the boot menu doesn't speak or beep, so it can be a bit tricky to know that you're there and which device you have selected. Trial and error is probably your best bet in this situation. If nothing works, you may need to burn the image to a CD. ~Kyle
