How to install Chrome OS alongside Windows 10

We are going to explain how to install Chrome OS together with Windows 10 , so that when you turn on your laptop you can choose between using Windows or the Google operating system. And no, we are not going to use one of those GNU / Linux distributions modified to look like Chrome OS, but the original system through one of its recovery files.

It is quite a complex process for inexperienced users, so I do not recommend doing it on a computer where you work unless you really know what you are doing. To be able to do the process, you will need a series of requirements, such as that your computer has the UEFI firmware , the replacement for the BIOS that you should have on your computer if it is after 2011 or 2012.

You will also need a USB of at least 16 GB capacity, as well as install a GNU / Linux distribution on it. This distro will be necessary to perform the conversion of the official Chrome OS recovery file in order to use it as an operating system image. You will also need other things, but we will provide all the links in due course.

There are several processes to install Chrome OS on a computer, but we are going to try one that has already been tested by the community . It is a delicate process in some points, but we will try to explain it to you step by step so that you do not get lost.

First, download the main tools: How to install Chrome OS

The first step will be to download a tool called Brunch . This tool acts as a framework that allows you to transform the official recovery of different Chromebooks into an image that will be able to be installed on a Windows PC. To download the tool, you have to go to its official profile on Github .

When you enter the website that we have told you about, you will go directly to the Brunch launches section. In it, you have to download the latest version that has the word stable in the name , since they are the stable versions that give less problems. In it, you have to click on the file with the .tar.gz extension to download it.

Now, you have to download an application to unzip the .tar.gz file . I’m going to use the B1 application , which is the one I’ve been using forever, but there are also good alternatives like 7-ZIP that can help you.

The next step is to download a Linux distribution that is lightweight to fit on the USB that we have told you before. We are going to choose Linux Mint, one of the most popular GNU / Linux distros , so we will go to its download page

Next, you have to download the Rufus application , since it is the one that we will use to mount the GNU / Linux system on the USB. Just go to the Rufus.ie website and download the latest version available.

Now you have to download a Chrome OS recovery image. In Android, a recovery is the image that all devices have with the essential files of the operating system to recover it in case of a failure, and Chrome OS has it too. Brunch will serve to make this recovery an installable image of the operating system , so now you must enter this website to download the system image.

This is one of the most confusing but important parts of the process, because on the recoveries website you will see that there are a large number of versions, how do you know which one you need? You will see that a code name appears to the left of each recovery, each of which belongs to one or more specific Chromebook models. Here, you will be especially interested in four of the versions , which you will distinguish by their code name, and they belong to Chromebooks with hardware more compatible with normal PCs.

If your computer has a 4th generation Intel processor or later, then you will need to download the latest rammus version from the list. If it’s an older Intel, then lower the rammus . The zork and grunt recoveries , meanwhile, are for the AMD Ryzen 3XXX and the AMD Stoney Ridge. When downloading the recovery, on the right click on the highest number, which will belong to the latest version released.

And finally, you have to download the install.sh script , which you have available at this Google Drive link to download it directly, or at this other link to copy its code and use it yourself if you know how to do it. This script is an executable that will execute in GNU / Linux a series of commands to create the Chrome OS image from the recovery file that we downloaded earlier.

Unzip downloaded files: How to install Chrome OS

Now, what you have to do is put the Brunch .tar.gz files , the script and the Chrome OS recovery file in a separate folder so that you don’t lose sight of them or get mixed up with anything else. For example, you can put them both in a folder called Chrome OS. It is recommended that the folder is directly inside C: so that later it is easy to find it. In the capture the time on the desktop, but it is only an example, it is best that you tips it in C: using the file explorer.

Next, you must unzip the Brunch .tar.gz file and the Chrome OS recovery file into that folder. You only have to unzip the recovery once, but the Brunch one twice. Inside the .tar.gz there will be a .tar file that you will also have to unzip.

Finally, you have to rename the recovery file . It will be called cromeos_blablabla.bin , with numbers and the codename. The file has to be renamed recovery.bin , since that is the name that appears in the script that we have downloaded, and in order not to have to modify that executable, it is best to simply run the file that it asks for.

Make room for Chrome OS alongside Windows: How to install Chrome OS

The objective of this guide is to install Chrome OS together with Windows, and for that it is recommended to create a partition on your hard drive to be able to install the operating system on it. To carry out this process, enter the application Create and format partitions of the hard disk that you will see when you type “partitions” in the start menu.

Once you open the disk manager, right click on the C: drive or the secondary hard disk where you are going to install Chrome OS (1). A menu will open with several options on things you can do with the unit, and in it you must click on the Reduce volume option (2). With this option, you will be able to reduce the partition of that hard disk and leave free space to create others in which to host the system.

The process is that simple because usually on the disk you will have a single partition. In the event that you want to install Chrome OS on an already partitioned hard drive, you will have to choose at the bottom the partition that you want to reduce to free up space and choose the option to reduce volume.

A screen will open in which you have to choose how much space you want to free from the hard disk partition. The only thing you have (and can) write is the size of the space in MB in which you want to reduce the partition, which will be the same space that you leave freed. Above the figure you will see the available space, and below the space that will remain for Windows once you have made the reduction. Once you have decided on the amount, press the Reduce button .

After making the changes, the Disk Management application will show you on the hard disk where you have made it a black space called Unallocated . This space is the size you have set before, and it is hard disk memory that is not partitioned. This is the memory that we will use later to install the Linux distro.

Do you need to disable Secure Boot?

One factor to consider when choosing a distribution is whether it can work with Windows Secure Boot protection . It is a protection that makes sure that no strange applications are run before Windows starts, and that it can block the launch of some linuxdistros. Distros such as Ubuntu are already adapted to work with this protection, but if you are going to use another, you should look in its documentation if it is prepared for it.

In the event that you want to use a distribution that is not prepared for Secure Boot, in this article we explain how to disable it from the UEFI. Of course, keep in mind that the decision to allow deactivating the mode depends on the manufacturers, so it is possible that there are cases and computers in which you cannot do it directly.

Install Linux Mint on USB

Now you have to create a bootable USB or executable with GNU / Linux , with Rufus and the distro that you have downloaded. To do this, run the Rufus app. Inside, above you have to choose the USB drive that you have connected to the computer to do this, and then click on Select to choose the file of the GNU / Linux distro that you have downloaded, in our case Linux Mint.

Once you have chosen the distro and it is loaded in Rufus, click on the START button to create the executable USB. Here, when you click on Start, Rufus will show you some dialogues, in which you have to accept everything he tells you. Don’t worry, it is a very well pre-set application, and all it asks and recommends will be standard settings so that everything works out correctly.

Install Chrome OS on your computer

Once you have it prepared, you have to start the computer from the USB that you have prepared with Linux Mint. To do this, turn off the PC, connect the USB and turn on the computer by immediately pressing the key that launches the drive selector to boot. Generally this should be F12, but depending on the BIOS and the PC it can be others such as F1, F8, F9, F10, TAB or ESC. When you see the menu, select the bootable USB drive and hit Enter to boot your computer through it.

When you do this, you will go to a screen where the computer will give you to choose from which drive you want to boot it. On this screen, you have to choose the USB drive with Linux Mint that you have connected and press Enter . By doing this, you will tell the computer that instead of booting through the hard drive, which is what it always does, boot directly using the USB as the main drive.

The first thing you will see is the Linux Mint welcome screen, where you will also be offered several options. In these options, what you should do is choose the option of Start Linux Mint , which means to start Linux Mint. This will cause you to boot the entire operating system from USB.

Once inside Linux Mint, the first thing you will have to do is connect the operating system to the Internet , since the process with Chrome OS will require it. Press the connection button, choose your WiFi in case the computer is not connected by cable, and enter the password.

Next, on the Linux Mint desktop you have to open the Computer folder . You will see that several elements appear with strange names, which are the hard drives that you have connected to the computer. What you should do is open the folder on your main hard drive , to be able to browse its elements.

Once inside the folder belonging to the hard disk, you have to access the Chrome OS folder that we have created before , in order to use the files that we have in it from Linux Mint. When you are inside the folder, right click on the background, and click on the Openin Terminal option , which will open the terminal having navigated directly to the Chrome OS folder.
