Installing Ubuntu on Acer Chromebook 13? [duplicate]

From reading your post, I don't think that post mentioned pressing Ctrl+L. The post mentioned pressing Ctrl+D and later on mentioned running the command curl -L -O http://goo.gl/s9ryd; sudo bash s9ry (by typing it on the command line and confirming with Enter)

This is Chromebook Specific from http://svn.clifford.at/handicraft/2014/chrbook13/README

This is the script I have used to install Ubuntu on my Acer Chromebook 13 CB5-311-T6R7 on 2014-12-12. The Chrome OS version pre-installed on the Chromebook was:

Version 39.0.2171.94
Platform 6310.61.0 (Official Build) stable-channel nyan_big
Firmware Google_Nyan_Big.5771.63.0

I am now running a dual-boot configuration with Chrome OS and Ubuntu. To boot into ubuntu I run "sudo ubuntu" in a Chrome OS Crosh shell session.

Here is a short write-up of te install procedure. I write this a few days after the fact, so it is possible that I get some of the details wrong..

This tutorial is based on the modified chrubuntu installer posted by reddit user arm000: http://www.reddit.com/r/chrubuntu/comments/2hhb31/

This script installs a basic ubuntu system and also the NVidia drivers the Tegra K1 processor and its Kepler GPU.

The script in this directory is a slightly modified version of the original script. Compare chrubuntu.sh and chrubuntu.sh.orig for details.

=> Reinstall Chrome OS in Developer Mode

This sound complicated but is in fact really easy. Simply press

esc + refresh (f3) + power

this will reboot. On the boot screen press Ctrl + D, then Ctrl-D again and then ENTER. This will re-install Chrome OS in dev mode.

When Chrome OS is in dev mode there is a long delay on each bootup. Simply press Ctrl-D on the boot screen to skip the delay.

=> Repartition MMC card

Open a Chrome window, press Ctrl + Alt + T to open a terminal window. Enter the following commands:

shell
cd ~/Downloads
wget http://svn.clifford.at/handicraft/2014/chrbook13/chrubuntu.sh
sudo bash chrubuntu.sh

This will ask you how much space you would like to reserve for Ubuntu. I chose 16 GB. After changing the partition table the script will reboot the device. The boot loader will then recreate the chrome os partition used for user content on the smaller partition, leaving the newly created partition for ubuntu untouched.

==> Installing Ubuntu

Once again, open a Chrome window, press Ctrl + Alt + T to open a terminal window. Enter the following commands:

shell
cd ~/Downloads
wget http://svn.clifford.at/handicraft/2014/chrbook13/chrubuntu.sh
sudo bash chrubuntu.sh

This time the script auto-detects that the target partition already exists and installs ubuntu.

Next install the launcher:

wget http://svn.clifford.at/handicraft/2014/chrbook13/ubuntu.sh
sudo mkdir -p /usr/local/bin
sudo cp ubuntu.sh /usr/local/bin/ubuntu
sudo chmod +x /usr/local/bin/ubuntu

Now you can boot into ubuntu by running "sudo ubuntu"
