  1. Press the Power button.
  2. You will get a message saying "Chrome OS is missing or damaged".
  3. Do not hit the Space bar!!!
  4. Type control-D, or just wait.
  5. Chrome will boot and you'll see the mountain/beach background.
  6. Click on "Browse as Guest" at the bottom.
  7. Type "shell" to get a ChromeOS shell.
  8. To the shell prompt, type "sudo startunity" to start Ubuntu.
