OK, that worked! I downloaded unetbootin (from Windows) and followed the instructions. The the live usb worked like a charm. At least, on my Lenovo. Will try also on my other computers. – Marco de Mol Oct 24 '12 at 12:58

I think it's the image. I've tried with the iso from 12.04 and it's working. But strangely, everytime I download the 12.10 iso this happens, so maybe something inside the iso isn't koosher. – Marco de Mol Oct 24 '12 at 12:49
