a memory stick. I used a utility to make a bootable memory stick and it worked fine but it is designed to install ubuntu not be the install. It didn't save the configuration. Is there a way to install it like on a hard drive? On a side not I plug my external hard drive into my laptop, it was the boot drive on my desktop until it took a crap, loaded up ubuntu, wireless works great this is cool. Hope they get the desktop fixed soon I miss it. Should of built it.
