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 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! When prompted for a password for the chronos user, use ‘password’ (without the quotes!).

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

Tested on Dell Studio 1555 with Intel 5100 AGN Wireless. Oh and VirtualBox of course. If you need instructions on how to use VirtualBox, go here and RTFM..

  1. Hey,

    I have been trying some linux distoro’s lately. They all seem to be saying my processor doesn’t have PAE support, the ‘forcepae’ kernel command seems to be working fine (Ubuntu booted A-OK with it), altho I don’t seem to see any option to enable it – it immediately throws me to the prompt that my processor doesn’t support PAE and that I need a appropriate kernel.

  2. Anyone else notice that the latest builds aren’t in developer mode
    I can’t execute shell in crosh or use crouton to install ubuntu.

  3. Awesome work…
    But is it possible to install it on a partition?
    With Hexxeh builds (long time ago) I remember I could dd it to the HDD… It’s something possible with this build too?

    1. I’ve been wondering this aswell.. As soon as i know it I will dd it. Currently I’m on a windows/ubuntu dualboot system with grub. It makes sense to `dd` it to a (empty) partition, but i’m hessitent to try it.

  4. I’ve been wondering the same thing as Giovanni. I’ve been trying to install Chromium OS to my USB drive, inside a partition, so I can have both the OS and storage from the 1 USB. Unfortunately all I’ve managed is getting the OS going, but I can’t add files like you normally can with a USB. Do you know of a way?

    1. If setting up in a partition the whole OS works, you could use the other free space (not the one in the partition) in order to have a NTFS/FAT32 partition and then put your files there…!
      It should work also on Windows, if it can’t read the other partition (if it somehow detects them and say they’re readable it won’t work)

      1. When I’ve been using the Win32 Image Writer, it’s been deleting my partitions, unfortunately. Then when I try to add a new partition, Windows does not recognise it because it’s not the first primary partition

        1. You just have to disable the other partition in Windows Disk Manager (setting them as not active)… How did you install Chromium OS on a USB partition?

          1. Had it worked for you? If so, hoe did you dot it? I’m eager to install on hdd!! I tried DD from USB install to unused partition, but it failed. Tried DD from too.IMG file to unused partition jut failed as well.

          2. When I set up the partitions, the Disk Imager would recognise one of the partitions as being the drive and I installed it as you would to an unpartitioned drive.

            I think it was either a Logical and Primary partition, or I installed it to the first Primary partition.

    1. Is that when you build it yourself? No, I’m using the image files and trying to write to the flash drive partition. I’ve noticed that when I write to the partition though, it just deletes the partition I’ve written to and creates a handful of new partitions for itself. When that happens there’s nothing I can do to make the partition I made earlier act as the primary active partition.

      1. I almost got it working (copying ChromiumOS USB partitions to HDD and setting grub to load them properly), I’ve just to find where the partitions mount are defined in order to fix them to my HDD ones (it still searches stuff as meant in normal Chromium OS and it doesn’t get a match)

      1. Well, I tried x86 version, it did not boot. It hanged on those file system errors
        EXT4-fs (sda3): couldn’t mount as ext3 due to feature incompatibilities

        This is the same mistake that x86 build is giving me on my intel notebook that runs x64 version perfectly.

        ctrl + alt + T does not give me a terminal.

        Any ideas?

  5. It is working just fine. but it is not shutting down properly… each time i have to shut down forcefully. can you give any solution???
    THANKS…

  6. Hello project member.

    I tried install and fun Cx86OS-20150311010102.img on my EeePC 1001HA. Now, I listen radio and watch many Video that put on flash from google-chrome-stable_current_i386.deb. It’s so wonderfull! Thank you a great image source.

        1. Hi Giovanni

          Regarding the –disk_layout 2gb-rootfs-updatable. Ill be looking to test that over the next couple of weeks and if its not too big an overhead, will be porting to the default builds.. Thats a brilliant find so thanks a lot for finding this!

          Graphics – I am still working on…

          1. You’re welcome, it’s just something I went into while looking for some GPT table modifications (seems people should have to edit the file with partition and rebuild a whole bunch of stuff… or something like that…!)

  7. I’ve tryed something other to boot from Live USB:
    Once i have downloaded the image, i renamed the downloaded image in *OS-20150314010101.img to *Camd64OS-20150314010101.iso!
    After that i’ve made an bootable USB Stick with the build in Tool from Linux Mint; i think it is also possible to do this with unetbootin.
    It still works and i can boot the Chromium OS from the Stick!

  8. So I now have Chromium OS 43.0.2331.3 running on my Acer Aspire One D255.

    And it seems to work remarkably well, though the microphone doesn’t seem to work, and while I can hear sound from YouTube, I can hear no sound from Google Play Music

  9. Never able to get any of the image to run, no matter it’s from USB stick or VirtualBox, for USB it got stuck at the “Welcome” screen , I can see the screen but it does not response of mouse click, except the Shutdown button on bottom left. Mouse point moves though.

    For Virtual Box I got SMBus error message

  10. i tried the latest 64bit build and it booted up fine but wifi module wasnt detected,anything i can do?my network adapter is : ralink rt3290
    will future builds somehow fix this?please help

  11. so i made a comment about this earlier but i am not sure it got through so i am making another.
    it booted up fine on my laptop but my wifi module wasnt detected,my network adapter is :ralink rt3290
    can this be fixed?will future builds do the trick?please help

  12. I’m trying to boot from USB, so I can install once running.

    Please help!

  13. Hello,

    Flash install not working anymore !!! :-(

    curl -L http://www.brash.ca/flash.sh | bash

    3.1 – Installing GNU ar.
    xz: (stdin): File format not recognized
    tar: Child returned status 1
    tar: Error is not recoverable: exiting now
    chmod: cannot access ‘/usr/bin/ar’: No such file or directory
    I couldn’t find GNU ar – can’t install flash, PDF or the MP3 plugin :-(

      1. Yup – if my flash.sh isn’t working, it was just a rebuild of sixsixfive’s.

        Sometimes the source files that the script downloads change online. I don’t run the script very often at all so when it breaks I depend on others to tell me.

        For now – use the script Gerd linked to. They all basically do the same thing… It’s just a matter of getting some library files from the Chrome browser source files.

        I’ll fix mine when I get a chance (no testing machines right now and won’t have one for about a week).

      2. Now, I can watch way more videos with the flash player plugin! Thx for that link! Btw Google Hangouts is still working just fine for me, just saying cuz I heard that it made Hangouts unable to work before

      3. Hey Gerd – tried that link but it failed as well.
        Right now mine is failing because the gnuar tarballs are no longer hosted on Google Drive like they were before.

        Not sure why that other one failed, I didn’t look into very deeply.

        I’m going to be re-writing mine when I get the time (probably next week).

  14. Hello I am on a hp Probook 6550b and the wifi led’s are flashing when wifi is connected how would I be able to stop the flashing I have had a look at some guides but they have not worked because the commands are not available. Thanks in advance

  15. hi arnold, i am in a bit of a soup. i am being able to downland your latest build 20150320010101.img file and everything. i am able to load it as well. the chromium logo comes up the screen gets alittle bright and dim again and then again the command prompts come up and thats it. it shows some inforation that kernel ……… something and the pc starts loading back in windows. i want to request you to please tell me which build will be right for my laptop?
    its a lenovo g510 3000 2 gb ram intel graphics its about 7 or 8 years old. i love the laptop and am sick of windows now and i’m in love with chromium. please help

  16. hi arnold moved a step ahead…. downloaded another date build this time 20150220010101. img now i got to second screen but wifi not showing only ethernet showing. baby steps. but will eventually get there i think. :-)

      1. Hi. Thanks for the reply mate. I did try the special build, the broadcom one, thinking that in the 22feb build, it didn’t show my wifi option, so i thought that I’ll try the one with the broadcom network adapter support. But nothing happened. I didn’t even get the initial boot screen. I’ve tried 5 builds including the broadcom one, one of 20 March, latest one, then 3 March, then, last 21 February. The only one that worked till the step mentioned above, Is the Cx086 20150220010101.img, the 22 Feb 2015 build. But i cannot do anything further in this one, because instead of wifi, it has ether net option. But my ethernet port shows ‘network cable unplugged’. Damn my luck. :-( I’m so anxious to get it working, please try and show me the way. If you could just tell me which build will work that’s amazing. My laptop is Lenovo 3000 g 510,its pretty old, but works perfectly. 2 gb ram. Intel graphics card. Intel 86 family chipset. Broadcom network adapters both wired and wireless. If you are suggesting the special builds then which one do you reckon I should try. I’m sorry to bother you mate! Please do help!

  17. I’m not able to enable Adobe Flash Player… How do I do it Arnold… I get a message that is installed by default on Chromebook…

        UPDATE: I’ve put the build. On my hard drive now. But the worst part is, I still don’t have wifi which is making everything well useless… So please help me if you know some codes that i can write in the developer mode. I’ve mentioned my laptop specs above. Can I get the update for the driver on the hard drive or something and run it from there.? Please. Any suggestions are welcome. If I’ve not been clear enough in explaining, please drop. Me a line. I’ll try again. Thanks

  18. Gidday. Have just tried the latest x86 build on a Toshiba NB500 and everything works except for resume from sleep. Any ideas on what I can do to get it to wake properly?

  19. Sooo… I just installed on my HDD. it from SD with a distribution from the end of the last year. Next, I updated it from the Settings/About screen. I says this is version 43; is this possible? Should I update it from the Dev channel from this site or have I done everything alright?

  20. Well, my Acer AO751h with all the horrible hardware, Poulsbo/GMA500 chipset and Broadcom wifi, seemed to boot pretty ok…

    Except that the UI never loads. It gets stuck in the terminal boot sequence… I can’t make it work…

    Been trying to download older special builds to see if anything works, but the download speed is so damn slow that it will take 8 hours to download.

    If there is any command I can type to make the UI appear in this latest build, it will be appreciated.
