"self-installing" being the key point. Those instructions require you to use some other piece of software to write the image onto your boot disk. In my case I used an Ubuntu livecd to download and write the image to the machine. It's obviously not a showstopper but it is slightly annoying.

I mean... That is how a lot of OSes are distributed: by giving you an ISO that you burn onto a USB dongle to install.

So... Same thing?
