Need Help Installing Ubuntu 12.04 on samsung Chromebook 3

view story

http://askubuntu.com – So I followed the instructions that were posted on How to install Ubuntu on a Chromebook 3? And everything seem to be going as planned until I got to the Last step where I was supposed to "configure wifi, open the terminal and run the script again. It'll download a bunch of files then reboot into ubuntu." After running the script wget http://cr-48-ubuntu.googlecode.com/files/arm-chrubuntu-3.sh; sudo bash arm-chrubuntu-3.sh for a second time and waiting for all sorts of files to download, My chromebook never rebooted into Ubuntu. I tried opening a terminal and typing sudo cgpt add -i 6 -P (HowTos)
