Hey guys I was looking to install Ubuntu on my Acer Chromebook 13 (CB5-311-T1UU) in the way outlined in on the comment made on this thread:
True Ubuntu on Chromebook ARM (samsung)
It appears that you can't fully remove ChromeOS from a Chromebook (well, you can but it really struggles) but you can make it dual boot and make it boot into Ubuntu by default. I'll show you the last method.
First make a backup of all you local files because everything stored locally will be deleted by entering developer mode.
Press and hold the Esc and Refresh keys together, then press the Power button (while still holding the other two keys). This will reboot your Chromebook into Recovery Mode.
When you get the yellow screen with the exclamation mark hit Ctrl+D (This will bring up a prompt asking if you want to turn on Developer Mode.) Press Enter (this will take about 15 to 20 min. You'll get a screen with a red exclamation mark but leave it be until it reboots into ChromeOS).
Turn it on but do not login. Make sure you have a WiFi or Ethernet connection configured at this point. 3G/4G is not recommended. Press Ctrl+Alt+→ (→ is the forward arrow where the F2 key would be on a PC). Do not use the normal Ctrl+Alt+→ method to get a shell. Use the Ctrl+Alt+→ method while no one is logged in.
Login as user chronos, no password is needed.
As the chronos user and without having changed directories or run other commands, run:
curl -L -O http://goo.gl/s9ryd; sudo bash s9ryd
(There is a new script with a new link. If you still want to use the old version you'll have to replace the new link with the old link)
curl -L -O http://goo.gl/9sgchs; sudo bash 9sgchs...
But it did not do anything when I pressed CTRL + L.
Does anyone know if there is a specific build for the Acer Chromebook 13?
