Fortunately for everyone who wishes to do any or all of these it is perfectly possible. The total amount of time for to complete all of the instructions should be about thirty minutes in total; this includes downloading of the Chromium OS, installing and downloading and installing the Chrome OS operating system over the top. Chrome OS also includes all the codecs and missing pieces from Hexxeh's Chromium build such as flash and mp3. Please read the disclaimer at the bottom of this article before proceeding. Not all hardware will boot Chromium and Chrome OS. I SHALL NOT GIVE OUT INSTRUCTIONS ON HOW TO CREATE A CHROME NUMBER TO RECEIVE THE GOOGLE DRIVE OFFER! DON'T ASK! How to install Chromium OS. Before you can get the official builds of Chrome OS you must first install Chromium onto your hard drive. To do this you must first make a bootable Chromium usb drive as described on Hexxeh's site here. Hexxeh gives very simple instructions on how to do this. Once you have made your bootable memory stick you then need to boot from it and quickly set it up so you can begin installing it to your HDD/SDD. 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. if you wish to dual boot you will need two HDD's as it is not possible to dual boot from just one. follow the instructions to dual boot at the bottom of this article! Warning! Installing Chromium into a hard drive formats the entire drive not just a partition. If you wish to dual boot you will need two HDD's as it is not possible to dual boot from just one. follow the instructions to dual boot at the bottom of this article! To install chromium simply boot into Chromium from the memory stick press and hold ctrl + alt and press t (you may need to alternate pressing alt and t while holding ctrl) and this will bring you to the Crosh command. Do this once you have logged in. Here you will need to run the command: install You will then be prompt for the username and password which are: Username = chromos Password = facepunch Some users will ONLY be asked for the password You will then have a few prompts to confirm you will lose all data etc, agree to all of these and Chromium will begin installing on your HDD, this took about two minutes on my currently set up with an i3. Once Chromium 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, HDD guru is the best tool to format as it is free and will format drives without damaging them, it also allows for low level format although you only need to remove the MBR. HOW TO UPGRADE CHROMIUM TO CHROME OS! The advantage about upgrading to Chrome OS is the added codecs and other little things that due to licencing Hexxeh is unable to give out but its already in Chrome OS. Before proceeding make sure you are logged into chromium and NOT using a guest account. To install Chrome OS is very simple, first you need to boot into a HDD installed Chromium OS and open the developer console CTRL + ALT + F2 ( you may need to alternate ALT and F2 while holding control. 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 and confirm that you agree with the shown agreement. There is now one more command that you will need to run that is the final step in installing Chrome OS. wget http://goo.gl/4suhf; sudo bash 4suhf Type the above command and then press enter. you will now be given the options for 13 different builds of Chrome OS, each build is for a different install such as the series 3 samsung chromebook, the series 5 chromebook, the series 3 chromebox and other chromebooks. Pick the build of Chrome OS you would like be typing the corresponding number and pressing enter. The script will then begin to download and install your Chrome OS for you, this will take about 5 minutes on a 100mb 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 ( 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 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. Once Chrome OS has been installed and you have logged in you will 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 install from earlier and as chromium 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!!!! Dual boot ANY OS and Chrome OS! Dual booting with Chrome OS is very simple if you wish to have ANY other operating system installed along side it. You can only dual boot using two HDD's as installing Chromium requires formatting the entire HDD and you then have no way of partitioning the drive until it is formatted. Simply remove the HDD with the operating system you currently use so you only have the hdd you wish to have Chromium/Chrome OS installed one and then the follow the steps to install Chromium/Chrome OS. Once you are satisfied with your Chromium/Chrome OS install, simply reinstall your original HDD to your computer and then pick your boot order in the bios. If you wish to boot to the other drive then you simply pick it as a temp boot during the boot sequence. Disclaimer: Auto-updates do not work on factory recovered Chrome installs and as such, to upgrade, the entire set up must be completed from a clean install of Chromium. I take no responsibility for any loss of data or damage to hardware or software that was caused by following these instructions. By following these instructions you do so at your own risk, understanding that with all operating system installs there is the risk of damage.
