Install Official Chrome OS



Repost due to accidental deletion. Oringinal content and support comments can be found HERE!

Chrome OS is the operating systems installed on Google's Chrome devices based on Chromium OS. It not only looks prettier but also comes with a few extras here and there.


Chromium OS, an open source OS made popular by the amazing Hexxeh and Arnold the bat. Since then, many have wondered how to get Chrome OS and I'm here to tell you how.

This will work with Apple OS X computers too, as long as they are Intel based and hardware compatible.

The total amount of time for you complete all of the instructions should be about twenty minutes in total.

Chrome OS also includes all the codecs and missing pieces from Chromium OS such as flash and MP3. If you wish to get the codecs that are missing without upgrading to Chrome OS due to any reason, there are instructions at the top of the screen on how to do this.

You must read the disclaimer which can be found here.


Instructions on how to dual boot can be found here or under the instructions heading.

All updates regarding this and anything else are now posted in the updates post.


Step 1. install Chromium OS.

First install Chromium OS onto your hard drive. Instructions on how to do this can be found here!


IF YOU WANT MORE HARDWARE SUPPORT THEN DOWNLOAD CHROMIUM OS LIME FROM DOWNLOADS AT THE TOP OF THIS BLOG. IT DOES NOT RECEIVE UPDATES ANY MORE BUT DOES GIVE EXTRA HARDWARE SUPPORT!!

NOTE: Not all graphic cards are supported, if you get a blank screen before or after the Chromium logo then try the on board graphics if possible, if not, your hardware may not work with Chromium.

Warning!
Installing Chromium OS on a hard drive formats the entire drive not just a partition. Remove ANY other drives you do NOT want Chromium OS installed to. This includes removable drives such as USB as SD cards. If you have multiple drives and can't remove them, follow these instructions to install.

Boot from the USB and follow the setup page, if you have no network try another build. If you used Arnold then use Hexxeh etc. 
Once you have set up your Chromium OS, log in using a Google account.
Now enter a terminal by pressing Ctrl + Alt + T. You may need to alternate between Alt and T while holding Ctrl.

Here you will need to run the command:
install

You will then be prompt for the username and password which are:

Username
chronos
Password
facepunch for hexxeh builds and password for bat builds

Follow the on screen prompts.

Once Chromium OS has installed, simply turn off your computer, remove your memory stick and turn back on.

You have now installed Chromium on your HDD.

You are now free to format your memory stick, instructions on a safe method can be found here. Do NOT use any other format method as there is a high risk of corrupting your memory stick.


Step 2. Upgrade to Chrome OS.

Boot into Chromium OS and open the developer console
CTL + ALT + F2

  • you may need to alternate ALT and F2 while holding CTRL.

Here you will need to type the command:
sudo su

Then you will need to follow the prompts for username and password as listed above.

There is now one more command that you will need to run that is the final step in installing Chrome OS.

bash <(curl -s -L https://goo.gl/1PhRNb)
Type the above command and then press enter.

you will now be given the options to select a build of Chrome OS, each build is for a different Chromebook/Chromebox and so hardware varies with each choice. Find a complete list with numbers here!


Note: If you do not get this far due to a read write error or other problems, you can continue by using the update method 2 mentioned in the instructions at the top of the page as this will allow you to continue.


Pick the build of Chrome OS you would like by typing the corresponding number and pressing enter.

The script will then begin to download and install Chrome OS for you, this will take about 2 minutes on a 120Mb internet connection.

Once the script has finished running you are ready to reboot.

(You will know if the script has finished running as you won't be able to exit the developer console by pressing
CTRL + ALT + F1

Reboot and you will now have Chrome OS installed!!!


If Chrome OS then does NOT boot, the image of your chosen Chrome OS install simply doesn't work on your hardware so just repeat the install of Chromium OS and try another build. If none of the recovery images boot then you will not be able to use Chrome OS and will have to stick with Chromium OS.


NOTE 1:


Be aware that booting Chrome OS will produce a message regarding malformed ID's. This is simply from a health check upon boot, simply close this and continue using Chrome OS. This poses no risk or issues. METHOD TO BYPASS IS UNDER INSTRUCTIONS.

NOTE 2:

Once Chrome OS has been installed and you have logged in you may receive an error stating that your account has been used on a higher build number than the current install, all this means is that your user profile has been loaded from the chromium OS install from earlier and as chromium OS uses a newer source code, Chrome OS thinks you have downgraded, to fix this simply go into settings -> advanced settings -> power wash, let this run for about two minutes and you will be good to go. YOU WILL LOSE ALL DATA WHEN DOING THIS!

  1. I just came upon your site... I'm sad to see no comments/answers on this issue. Do you have a suggestion for the right Chrome OS recovery image for a Dell Optiplex 330?

    1. The Chromebook Pixel (Non 2015) build should work rather well with this. Sorry about the loss of comments, I was unable to restore them when I deleted the post by accident.

    2. Thanks for the tip, Taron! I assume you mean build #26? (I can't see the first 10 because the list is long.) That build does seem to go further than the others I tried, but it gets to the white screen with Chrome logo and just sits there. I can get to the developer console if I press ctrl+alt+F2, but it isn't booting into the normal gui. Do you have any more suggestions? Thanks!

      Delete
    3. Ah, thanks for letting me know, I hadn't thought about the length issue! If you can get to the developer console then you can just run the script again and pic a new build. Are you using a graphic card or on board graphics?

      Delete
    4. Just the on board graphics.

      Delete
    5. Hmmm unsure as to why this would fail then. Try the samsung Chromebox. This should work quite well as it uses all intel chipsets.

      Delete
    6. The console seems to work (generally), but when I run the bash command, it seems to do nothing... just returns the line, which says "localhost user #". In other words, to try a new build, I think I need to re-install Chromium. Unless you have another idea first? Thanks...

      Delete
    7. Ah, it appears to have got caught between the system terminal user and a local terminal user. Try the command 'su chronos' and you shouldn't be asked for a password and then try the bash command again. If not you will have to start again from Chromium OS. sorry

      Delete
    8. I appreciate the help! I did need to reload Chromium again. I think used the Samsung Chromebox like you suggested. It now boots into Chrome! It is giving that "malformed hardware id", which is annoying but I assume is normal (?). The real problem lies in that it randomly reboots and is not updating beyond Chrome 44 (does this correspond the Chromium I installed on it ?). Is there any way to update it and keep it stable? Thanks!

    9. There are instructions on how to update chrome os on the instructions pages. The current build for chrome os is 45 but this was only released on the 22/09/15 and so Google may not have updated their recovery files yet.

    1. I have the same problem when trying to upgrade an install on my Chromebook (don't ask why I installed chromium on a Chromebook...) It downloads fine, but after unpacking the zip, says that /dev/sda12 is missing. Sure enough, running ls in /dev shows I have no such thing as sda12.

  5. Also, I have stupid Acer Tiano Secure Core BIOS, that absolutely REFUSES to boot from EFI (I am currently using MBR Mac OS X on the HDD of this Aspire 4752... 8GB Core-i3 2xxx Hyper-threading.

    I noticed /dev/sda12 references EFI, so thinking that might be my problem?

    ReplyDelete
  6. correction... I meant to say absolutely REFUSES to even SEE GUID partitions as bootable (so no EFI boot whatsoever).

    ReplyDelete
  7. I just noticed the script, would it be possible to remove all the chrome-EFI-mount stuff down the bottom, and will it still be bootable via MBR without that? Pretty sure ArnoldTheBat's builds use MBR GRUB to boot...?!

    ReplyDelete
    Replies
    1. unfortunately it isn't possible to change it, this is due to Chrome OS "requiring" a secure boot however it can boot without it. You should be able to change your BIOS to a legacy based boot to which this should then work for you. This will work for a USB drive too but you have to use "chromeos-install --dst" (dst being the location of the usb drive) to install it to your usb drive.

  15. Hello everyone! I succeded to update to chrome os using a lot of images, most of them worked for me.

    My computer (HP Stream X360) has a broadcom wifi card, and no image made it work.

    I want to boot in developer mode so i can try to install drivers using this (http://arnoldthebat.co.uk/wordpress/2013/02/24/how-to-get-the-broadcom-wireless-drivers-working/).

    I cant boot in recovery or developer mode (esc + F3 + power). Any idea how to achive this?

    Any idea which build might work for me? So far I tried:

    Samsung Series 5 (no splash screen - black screen)

    CR48 (Got to splash screen but can't seem to get past it, CTRL+ALT+F2 does get me to the dev console so im not sure if there is a workaround to get it to functional?)

    Please free up some space on that filesystem, or specify a temporary directory on the commandline like so:
    WORKDIR=/path/to/some/dir /dev/fd/63

    What should I do? Don't know how I would clean it up or specify a temporary directory.
