After several months of happily chugging along on the Samsung ARM Chromebook as my secondary laptop I decided to give ChrUbuntu a try, mainly because I wanted a LAMP environment to play and didn’t want to mess with my work-issued MacBook Pro. I installed ChrUbuntu to an external SD card, which gives me the flexibility to boot into ChromeOS anytime I want to surf the web and plus the SD card in anytime I need Linux.
I found the installation of ChrUbuntu to be pretty straightforward. Overall it took me about one hour from start to finish. I mostly used this Ars Technica guide and made a few adjustments where the steps between the Acer C7 and Samsung ARM differed. I also got some help from the 200+ comments on Jay Lee’s blog.
Here’s how to do it:
Don’t forget the SD card
Sadly the most obvious step was the one I forgot when I first tried this. Turn off your Chromebook and plug in the SD card you want to use. The card has to to 8+ GB and will be /dev/mmcblkp1. This will be important later. Also beware that any files stored locally on the Chromebook will be wiped in the following steps, so save them before you proceed.
Boot into ChromeOS developer mode
There are several steps for getting into developer mode and it can take 5-10 minutes. If you need additional help, the full instructions are available here.
To get into developer mode you have to hold the ESC and REFRESH keys as you press the Power button to get into recovery mode. Once you boot into recovery mode ChromeOS will ask you to plug in recovery media. Instead you have to press CTRL+D to go into developer mode.
Prepare the Chromebook for ChrUbuntu
Booting into developer mode will take several minutes as the Chromebook reboots and resets itself. Once that process is complete you get a screen telling you that OS Verification has been turned off. Press CTRL+D to get past that screen and click through the prompts you get after the Chromebook boots. You want to connect to a network but do not go past the login screen.
At the login screen, once you are connected to a network, press CTRL+ALT and the FORWARD key to go into the developer console.
In the developer console, type chronos and hit enter to get into the shared user account. Then switch over to the bash shell by typing sudo bash and hitting enter. The last step here is to type the following command:
This will boot you into the development BIOS each time you start your Chromebook and you’ll be able to hit CTRL+U to dual-boot into ChrUbuntu.
Use wget to download the latest version of ChrUbuntu
If you’ve done all of the steps correctly you are almost ready to start downloading ChrUbuntu. Type exit to drop out of the bash shell and type the following command to wget ChrUbuntu. This is the correct command for now, but may change in the future as updates for ChrUbuntu are released, so check Jay’s blog for the last version.
wget http://goo.gl/34v87; sudo bash 34v87 /dev/mmcblk1
ChrUbuntu will check that you are running a developer BIOS, that your Chromebook is compatible and that the target drive is plugged in. Hit enter and you are set. Also, it’s probably a good idea to plug your charger in a this point.
Grab a cup of coffee while ChrUbuntu loads
ChrUbuntu will now automatically download and install. How long it takes depends mostly on your Internet connection. With my 30mbps it took me about 30 minutes.
Some people have reported various errors at this point, either with the same file trying to load over and over due to a discrepancy in the hash value or an error that says Cannot write to ‘-’ (Broken pipe). I didn’t have these errors myself but the easiest workaround (according to the comment section) seems to be to restart the entire process.
And that’s it. You now have ChrUbuntu installed on the SD card. Anytime you want to boot into Linux plug the SD card in and hit CTRL+U at the Chrome OS Verification screen.

I have a xe303c12 arm chromebook.
I tried many times to enter dev mode using esc/refresh and power buttons but nothing happens.
The chromebook reboots normally…
Did I miss something?
Hi, I followed the instructions, but when I go to boot into it by hitting ctrl+U all I get is 2 beeps and nothing else. Is there something I did wrong?
I need some help please. i have tried to install chrubuntu on my samsung chromebook with the exynos chipset. the chrubuntu install seemed to work but i cant load the chrubuntu environment on my chromebook even though the ssd has been re partitioned. i used the tnyga script to do the process but now im stuck in the middle. i have a 2gb chromebook and cant restore it to the 16gb or install chrubuntu properly.
I have tried to do a full restore from google but the the chrome route (chrome://imageburner) doesnt work as it wont write to either sd or usb and the linux version writes the disk but the chromebook does not recognise the operation system on the sd / usb
my chromebook is showing as snow hector but its unclear which number to use off the script provided by google
German actually WORKING tutorial: http://ardogeek.blogspot.de/2013/10/anleitung-installation-von-chrubuntu.html
ok it finished downloading on the sd card but when it rebooted and i clicked ctrl u it beeped and nothing happened? what did i do wrong?
Also, seeing as the chromebook has usb 3.0 could the process be used to run the chrubuntu from usb3.0 stick / drive instead of the sd card
–mode=todev should be --mode=todev
If i want to do exactly that on a samsung chromebook series 550, except install Ubuntu straight onto the SSD, instead of an external SD card. Is that possible? Can you send me the commands for that
@futuretechsource Yeah, I'm having the same problem. Not sure how to get around it.
@rudyf If you haven't already checked out this blog post from the guy who developed the Chrubuntu script, this should help. I followed the instructions and got Ubuntu 12.04.3 LTS working on my chromebook. http://chromeos-cr48.blogspot.com/2013/05/chrubuntu-one-script-to-rule-them-all_31.html
@wannabeubuntu Hi, try that tutorial: ardogeek.blogspot.com
seem to have it sorted now (well back to a full size chromebook anyway) i think there were 2 issues for the record
the sd card and the usb stick i tried needed a fresh format with gparted
then i used option 2 for the linux recovery script from google (which seems to create so many partitions on the media its unbelievable, but hey its worked
Thanks to everyone but for the record see this discussion which may offer additional help
@ardogeek Installed this today and it worked like a charm. My German isn't great but I was able to get through it. I strongly urge anyone on a Samsung ARM Chromebook installing to SD Card use this option.
@zachattackmd same here !
@lostinlinux I believe it's possible to adapt the instructions. The 1st USB drive plugged into an ARM Chromebook will be /dev/sda instead of the sd card /dev/mmcblk1
@lostinlinux As far as I know this is something that will have to be done manually. It's fairly easy to Google instructions though... But yeah, 'melting speakers' certainly warrants feelings of trepidation =)
@yourcyborg Thanks for pointing this out. I may have written the article in Word, which tends to turn two dashes into an en dash.
I am sure you would like what works and what do not works prior wiping out the chrome os
@futuretechsource I'm beginning to suspect that there's a memory failure happening somewhere, either in the SD card or just in RAM. Not sure how to verify that, but it sure feels like memory failures I've seen in the past.
@aemathisphd1 i think i should write a english one, too ;)
@futuretechsource Yep, that was it. The SD card I was using (PNY StorEDGE 64GB) didn't like the Chromebook. I replaced it with a Samsung microSDXC UHS-I PRO 64GB and it worked on the first try.
@wannabeubuntu @ardogeek We're assuming you have some form of ARM Samsung because this happened to us. After 9 hours of hopping around solutions we were able to install it. You will need the one script to rule em all here: http://chromeos-cr48.blogspot.ca/2013/05/chrubuntu-one-script-to-rule-them-all_31.html
enter developer mode, make sure to be in BIOS as well by doing chromeos-firmwareupdate --mode=todev
then just simply type in curl -L -O http://goo.gl/s9ryd; sudo bash s9ryd ubuntu-desktop lts
itll go and show you the OS verification screen. press ctrl U. wait for a bit, then itll boot into chrubuntu
