I just received the new Dell XPS 13 Ultrabook and I'm trying to install Gentoo but I can't get install-amd64-minimal-20120223.iso to boot via a USB key. I installed it to two different USB keys via unetbootin but I get this right after it asks for the keymap:
Looking for the cdrom Attempting to mount media:- /dev/sda1 Attempting to mount media:- /dev/sda2 Attempting to mount media:- /dev/sda3 Attempting to mount media - /dev/sda4 Media not found No bootable medium found. Waiting for new devices... Could not find CD to boot, something else needed! Determining root device... Could not find the root block device in . It must be reading the USB key fine or it never would have gotten that far. Maybe it has no drivers for the disk controller, but then why does it reference the cdrom? I tried the nosata and ide=nodma options to no avail. - Grant
