Ubuntu 10.04.3 USB stick is not functioning

[Agmenor]

I created a USB installation stick with Ubuntu 10.04.3 on it, using Startup Disk Creator and the image downloaded from ubuntu.com. The process went slow, but with no error output.
Now, when I try to boot on that key, I have the following written of my screen, before anything else:

SYSLINUX 4.04 EDD 20110518 Copyright (C) 1994-2011 H. Peter Anvin et al

(etc)

Tested on two different machines ; an Acer laptop and a Lenovo desktop.
