How to Install Linux on the Acer C720

Acer’s latest Chromebook, the C720 has improved in almost every way from its predecessor, the Acer C7. It now has a thinner framework with sides measuring just 19mm in thickness and has been completely redesigned, featuring few design cues from Samsung’s Series 3 Chrome book. The most exciting addition to the C720 is perhaps a Haswell processor, a dual-core Intel Celeron 2955U with 1.4GHz clock speed and a 2GB of RAM, which makes it one of the quickest Chromebooks in the market. Steps for installing Linux in Acer C720 To install Linux on Acer Chromebook C720, first of all you need is to enable ‘developer mode’ on your Chromebook. Google will warn you and you should keep in mind that all the modifications you make to the system are not supported by Google. They may cause hardware, software or security issues and can also cancel the warranty.

This guide is using the Crouton Installation method if you want to install linux by default please consider our step by step by step guides where we explain how to solve the touchpad problem and make the Seabios default for a quick boot without pressing any keys.

Step 1: Enter Developer Mode

  • Press and hold the Esc+F3 (Refresh) keys and then press the Power button. It will enter recovery mode.
  • Now press Ctrl+D and the system will ask you to confirm. Once you confirm the process it revert system state and enable developer mode.
  • Press Ctrl+D , or at the white boot splash screen to enter Chrome OS wait 30 seconds for the beep and boot)

Step 2: Configure Google Chrome

  • Once you have changed the developer mode now configure Chrome OS so that you can log in.

Step 3: Enable the Legacy Bios

  • The next step is to open a crosh terminal with the Ctrl-Alt-T keyboard combination. It is a limited Linux shell.
  • Start full Linux shell with the command: shell
  • Or become supper user with sudo bash.Be sure to enter this command: sudo sh -e ~/Downloads/crouton -r list

Step 4: Enable Legacy Boot

  • with the help of the following Command:

# crossystem dev_boot_usb=1 dev_boot_legacy=1

Step 5: Reboot the Machine

  • Start Sea BIOS now by pressing Ctrl-L at the white boot splash screen.

Step 6: Installing Arch Linux or any other distro like Ubuntu

  • First of all create a USB drive with the Arch Linux installer.
  • Plug the USB drive into the Chromebook
  • Start SeaBIOS with Ctrl-L command at the white boot splash screen.
  • Now Press Esc to get a boot menu
  • The last step is to select the number corresponding to your USB drive.
  • The Arch Linux installer boot menu will appear, however in case of any trouble follow your installation guide.

Points to Ponder

  • For a 64-bit installation you should use the 2013.10.01 ISO and then boot into the x86_64 installer, with the option of mem=1536m kernel.
  • Though a fresh DOS partition table on the SSD with one bootable 16GB root partition will wipe out Chrome OS but it works best.
  • For now instead of Syslinux choose GRUB as your bootloader
  • It’s Ctrl + L to boot not Ctrl + D after installing ( a little trick which will save you hours figuring out why you can’t boot)
