The error you're getting means the installer is not booting, so it's either not been burned or written correctly or you're not booting it since it is instead trying to boot the HD. It should normally even boot itself if the HD is wiped, so it may be written or burned badly.
If you wrote a confirmed ISO to flash stick using UltraISO as given then it should always boot, providing you're tapping the correct key to trigger the one-time BIOS Boot menu, with the HD set first to boot in BIOS setup. Flash sticks are listed on the Boot Menu under USB, Removable or HD's You may need to expand a listing to see the stick name. Then select it and see if it loads. If not describe exactly what happens.
