Is there a better way to image this to a flash drive? The first boot option hangs on "loading device drivers," the second one gets past that and then hangs, so does the third. I had no problems installing Proxmox 3.4 to this hardware so I feel like it has to be the way I'm writing the ISO to flash -- especially since it weirdly asks me if I want to overwrite /dev/ttyS0 and other tty devices when I'm writing it.
