I read it as meaning that the USB stick works as a live system (first boot), but not as an installer (second boot). Which makes me wonder about earlier discussions (maybe months ago) concerning whether installing Debian from a live stick can be problematical (though I don't remember the nature of the problems people had). I've never tried it. Cheers, David.
