Enter BIOS and check hard drives priority. If you'll see your stick in hard drives list (under 'Boot' section), move it to the first position. If you have no your stick mentioned there check for USB boot option, it should be enabled.
Another way to boot is lanching Boot Menu. How to launch it depends on your hardware, usually it is F2, F8-F12 or Esc key.
Was able to boot from the USB stick by looking, as you suggested, on the hard drive list and choosing the USB stick. I can't make it boot any other way
In my Phoenix Award BIOS Vr.IX58SZ83, Chipset Intel 3400 rev.18, the hard drive list is the very first line on the Boot Order Menu List, selecting that, showed the HDD and the USB Stick.
Thank you very much as this is the way in which I'll be able to Boot from USB.
