There's no "might" about it. At no time in this long thread did you
mention that you had successfully booted the stick in another computer
AFAIR. All along the stick was fine and the problem was limited to one
particular computer, and old one that apparently has problems booting
from some USB devices.

You may find that toggling some of the USB settings in the BIOS helps.
