Chromium OS

Chromium OS is an open-source project that aims to build an operating system that provides a fast, simple, and more secure computing experience for people who spend most of their time on the web.

All downloads are located at http://chromium.arnoldthebat.co.uk/. This will be updated daily where builds compile succcessfully..

Build Instructions for USB

  • Linux
    1. Use p7zip to extract the IMG file from the downloaded file.
    2. At the shell, run the following (where sdX is your USB stick and ChromeOS.img is the path to the IMG file you extracted):
      dd if=ChromeOS.img of=/dev/sdX bs=4M
    3. Boot from USB stick
  • Windows
    1. Use 7zip to extract IMG file from the downloaded file.
    2. Use Win32 Image Writer, then select the IMG file and select the USB device from the menu.
    3. Click on “Write”.
    4. Boot from USB stick

All builds based on x86, amd64 and ARM generic board.

If you want to install to your hard drive, follow the instructions here and here. Heed the warnings noted in the links!

Please note: there is a new behaviour with the chronos user password. The password has been removed from build R55-8777 onward and will continue to be removed for better overall security. Older builds have the password of ‘password’.
This means you need to use ‘chromeos-setdevpasswd’ from either shell or console to set your own password from build R55-8777 onwards.

By default, this also disables SSH access so if you also need this level of access, you will need to set a separate password using ‘sudo passwd chronos’. This allows the password for dev access and SSH access to remain separate if needed.

You can also just set a password using ‘sudo passwd chronos’ and this will allow for both dev and SSH access if you need to keep them the same. Do not use ‘chromeos-setdevpasswd’ if you want to keep the passwords the same.

Once installed, you can update from the Dev Server noted here.

      1. Hi, Arnold. I have to say I’m extremely impressed with this. Currently running your most recent 64-bit Vanilla build from just a few days ago, on a new HP compact tower from a USB 3.0 SanDisk thumbdrive. Absolutely everything works!

        Question (if I may?)

        How do we get PepperFlash and Widevine installed here? I normally run ‘Puppy’ Linux, so I’m well used to diving into the file-system & manually moving things around, linking/re-linking, changing permissions, re-assigning ownerships, etc, etc. But we can’t do that here, can we?

        So; what’s the easiest, current way to do this? I’m guessing it involves the terminal, doesn’t it? (I HATE the terminal….

        1. @ Arnold:-

          Okay. I see a couple of what I presume are install scripts, yes? So…..talk me through this, would you? It’s been nearly six years since I really did any terminal work, and that was in Ubuntu 14.04 ‘Trusty Tahr’.

          I’m what you might call a bit ‘rusty’ with this kinda thing, ‘cos Puppy, being a hobbyist system, kind of encourages you to literally tear it apart & re-build it the way you want it. We don’t tend to bother with the terminal much, except for trouble-shooting & such-like, because most of us prefer to get ‘up close & personal’ with the file-system itself.

          It shows, don’t it? ( lol )

  1. I am currently working on converting a LENOVO ThinkPad E325 to a chromium device for my daughter. There is an AMD Fusion 450 CPU and a Radeon HD6320M graphic chip inside. I can boot the Live usb, but then I get screen flickering, wich stops the USB live boot before I can install. Making it impossible for me to do anything but watch the screen flicker. Anything I can do to fix it?

  2. Hello, thank you very much for all the work.
    I have an Asus E205SA and already tried cloudready neverware but the mouse of the touchpad became very sluggish and the touchscreen didn’t work (albeit sometimes it worked for one of two actions). Which build would you recommend?
    Thank you very much in advance for your reply.

      1. Hey, do you have any update on the rtl8821ce wifi driver? Is there something we can do? Would be amazing if this is supported!

  3. Hey Arnold, I have a Lenovo S130-11IGM. Latest daily amd64 starts up but fails to find the touchpad. I can see it in linux as “i2c-SYNA3269”. Plugged in a mouse to move on but doesn’t look like the network adaptor is supported .. “Realtek 8821CE”. Tried the special build with the same outcome. spun up a VM and built from latest sources but still the same. Realised I have no idea how to add drivers during packaging 🙁 . Any suggestions. Many thanks.

      1. My WiFi isn’t showing up, is there anything I can do? I have the intel centrino advanced n6205, it’s a Dell latitude e6330. I tried following an old guide you posted but, because it was an old kernel, i couldn’t do it. Thank you

  4. Does the vanilla build support enterprise enrollment, i am going to be using mine for school and I want to know which to use. Also the amd64 R76 downloads as a .bin not .img, how would i install this then

  5. How can I turn on my Qualcomm Atheros Wifi driver? Everything boots up fine except for my Wifi Driver (Qualcomm Atheros QCA 9377).

  6. Hi,

    My Samsung XE303 chromebook with arm cpu stopped updating and i am looking for a solution to install chromium os.
    1) Can i use arm .img files so i can replace chrome os?
    2) Is there any tutorial how to install the arm builds?

    Thanks

  7. Can’t get WiFi to work – it just doesn’t find any networks and when manually input my WiFi hub details in, it says network connection error. Using x86 vanilla (the latest version of it) – please help! I don’t understand what’s wrong 😅

  8. why does the latest special dl extract as a .bin vs .img file? how do i create a bootable USB from a .bin?

    also it is 9 GB, i thought we only needed an 8GB USB drive.

  9. Hi author. Works great when i run this os from usb stick. Any simpler way to install this on full hdd drivr in my old Toshiba Notebook? And last question. How i can run android apps?

    1. If you can take the drive out of the Toshiba and put it in a USB case you can then install as if it were a USB drive (gpt partioned). I used the “dd if=ChromeOS.img of=/dev/sdX bs=4M” command line method on a Linux machine to create the drive with all partitions. Linux also has the partition manager gparted so the main partitions can be moved/resized. I moved partition STATE so that ROOT-A could be resized to 4Gb and STATE could then be resized to fill the disk space for user file usage.

  10. Hello Arnold, I’ve been trying to find a way to make this run in a VM in Virtualbox to no avail. Can you please help me out with this?

  11. I apologize up front for my lack of knowledge. I run into the problem of size of iso is too large for a fat32 8gb usb. When I try to create my usb drive, it gets partitioned into many drives and does not function. Then I have to low level format my usb drive back into working condition. Maybe you have a hint for me on how to correct?

  12. Hi,
    After rebooting laptop hp compaq 6720s to install chromium os from USB is a problem with WiFi connection. Looks like wifi card is not working because any network is on the list but there are some of them and also my network shall be there. Without the step with connection to network installation can not do next steps. How I can solved this problem ?
    Thank in advance.

  13. Hey Arnold, thanks for all the work you put into these builds, ive been using them for a couple years now at home/work (Im a K-12 network admin, so turning old computers into “free” chromebooks is really helpful for our limited budget) One thing ive always struggled with is getting wifi to work on basically any of our old macbooks/mac desktops. The wireless card is always the same, BCM43XX rev 1.0 firmware revision 5.10.131.42.4. Ive tried several times to find/install drivers for it, and havent been able to get one that works. It would be easier for me to just swap the wifi card with a currently supported model, but due to artificial limitations……….I mean features……….imposed by apple most of the wifi cards that I have avaliable to me are not physically compatible with computers other than the ones they came out of. Is it possible or even on your radar to get driver support for this model WLAN card? I know its old, but I have a good amount of computers that I can convert into chromebooks if I could figure out how to get wifi working.

    Also the trackpad doesnt seem to work on 2014 macbook airs, I have put 0 effort into figuring out why, and I honestly dont care either, they can use a regular mouse. Just figured I would mention it as well.

      1. Thanks for the reply, I was testing on the latest Special build, and I just made a USB with the latest Alpha build, still no luck on wifi. Ill be the first to admit Im not some super duper linux admin, 99% of my devices that run linux are just ubuntu containers inside my proxmox environments, but I tried most of what I can think to try, and (to me) it seems like there arent any versions of this driver that are compatible with the 4.14.141 (.152 in the alpha build) kernel. Ive been digging around the internet, playing around with modprobe and generally trying anything to get wifi working but im stumped. Ive been keeping a small doc with notes and things ive tried, and I have found a precompiled version of the drivers for the 4.4.14 kernel, but that didnt end well….I will past some of the more useful links ive tried (no point in pasting my notes, theyre barely readile even to me :P) Im sure you would be able to make better use of them than me, or even if you look into it and its too much hassle, even just telling me that it cant and wont work would be fine, I have plenty of other projects to bang my head against 😀

        Thank you,
        Sebastian

  14. Running this beauty on asus 131t.

    Downloaded the special image, put it on USB with balenetcher, booted it and ran: sudo /usr/sbin/chromeos-install –dst /dev/–targetdrive–

    which in my cased seemed to be /dev/mmcblockxx
    Kinda weird but!

    Everything seems to work. Nice Job!
    Going to see what ChromeOS can do 🙂

  15. It’s possible to add something like Proprietary Media Components (from Cloudready) in special versions
    I can’t play videos (Youtube, Facebook) in either version.

  16. Dear Arnold,
    may I ask how to install the OS.
    It works fine as a live system-thank you!
    Please specify the command I must type into the console.
    Thanks, also for the OS itself.
    Regards

    Using a Trekstore Wintron 10.1 ” “WIN-” Tab from 2014
    (All-x64-archictecture BUT w/ an x36-UEFI)

    Not working would be e.g.:
    ” /usr/sbin/chromeos-install –dst /dev/[harddisk code] “

  17. Hello,

    I’m trying to install Chromium OS on my daughters new PC I build (Specs Bellow), I have tried all three ALPHA (80, R78 9-8 & R78 9-29) images and I keep getting stuck on this screen with all of them:
    https://ibb.co/tbMFZYb

    I use a 32GB ScanDisk Cruzer Blade on my windows 10 PC to burn with Win32Disk Imager, and the only think I noticed that’s weird is that it creates a ton of partitions when doing so and don’t know if that’s normal. I was able to do a thumb drive boot pf ChromeOS with CloudReady on this before, but it crashed when clicking on links on chrome web sites. So that didn’t work, so trying more costume versions on your site. Any help would be greatly appreciated.

    ~Thanks~

    1. Arnold,

      Was your reply to my post? Sorry I can’t tell, but if it is thank you. I will try this, but when you say “graphics card”. Do you mean the integrated Radeon RX Vega 11 Graphics my processor has?

      Thanks,

  18. I am trying to install this onto my Lenovo yoga c630 (windows, not Chromebook), so that I can use chromefy. My laptop has a snapdragon 850 (arm64) processor, I’ve tried making a bootable usb with the daily and weekly arm versions, but my computer just continues to boot into windows when I select the usb (its always labeled usb partion 12. Any ideas on where I am going wrong? I have configured my BIOS settings to allow booting from usb, but the same thing always happens.

  19. I’m using lenovo e41-15 laptop with QCA9377 wifi card and it’s not working on any of the vanilla and special chromium build. What should i do to make it working?

  20. hello. i downloaded latest release and used 7zip then installed it with rufus, unetbootin, win32imagewriter and etcher and tried another pack but never boot it from my usb. i installed another linux distro on it(puppy) it worked but this one not booting

  21. Hello, arnoldthebat,
    Thank you so much for the great builds. I have successfully created and installed chromefy img using your special build. Everything is great except wifi. My wifi signals are too weak. I am using rtl8723be card and it works fine in windows. I have tried many solutions but nothing worked for me. Another problem is I can’t enable developer mode as I am not using a real chromebook and I really need to access system files. kindly help me fix the wifi issue and guide me on how can I get access to system files without developer mode or help me to enable developer mode on non-chromebook hardware.
    Thanks in advance

  22. Hey there! I’m curious about trying out one of your images on a Pinebook Pro. Is there any helpful information about your generic ARM images you could offer? Does it use a specific u-boot, or have known incompatibility with any ARM boards?

  23. Hi, I was wondering if there was a way to get one of your builds of Chromium OS working on something like VMware Workstation Player or VirtualBox?

  24. Hi – I have an Acer Chromebook 13 CB5-311. I have tried to boot from the USB drive with an image to replace ChromeOS, but the Chromebook just hangs with a blank screen. Is there anything I could try?

    Thanks

  25. Dear Arnold,

    I install the CHROMIUM OS version CARMOS-20200207010101 to DELL LATITUDE E5430 Laptop during startup the issue is (Invalid partition Table! and Wifi is not working with Intel Centrino Advance-N 6205 and the Video Card driver Intel HD Graphics 4000), will you please help us which correct version of CHROMIUM OS should i need to download and install to my laptop, please send to me the link to download

    Regards,
    Rolando Villanueva

  26. Is there any way you could add support for newer ARM64 devices (specifically the Galaxy Book2/S and Surface X)

    Windows on ARM feels much more restrictive than CrOS would, thanks for your work, sir!

  27. Hi thank you for such a commendable job with the OS. Really appreciate it. How can we run this in VirtualBox? Is there going to be a virtualbox friendly version of this?
