How To Dual Boot Windows 10/11 And Chrome OS With Play Store

Windows 11 is on the verge of taking down Windows 10 and previous versions of the Windows operating system. Most of us have already upgraded to Windows 11 and have adopted the new environment, while there are many ups and downs with the new modified operating system. Other operating systems are getting upgrades, too, with pretty exciting features, such as the Chrome OS.

Chrome OS is one of the lightest operating systems, and any system with 2GB RAM can handle it easily. The OS is Linux-based, which means you can do pretty much anything with the Linux commands. However, Chrome OS is a bit different from other Linux distros as it is based on the operating system that we commonly use on Android smartphones and other devices. In Chrome OS, you also get the support to install the Google Play Store that provides a wide range of apps and games for free.

Install Chrome OS and Windows 10/11

Now you can install both Chrome OS with Play Store and Windows 10 or 11 on the same hard drive and dual boot either of them at a time. Installing both the operating systems might take a lot of time and needs some specific software to be downloaded first. In this article, we have written a detailed guide on dual boot Windows and Chrome Os with Play Store. So let’s get started.

Install and Dual Boot Chrome OS and Windows 11

Before we begin, I would like to mention that this tutorial involves complex operations and a lengthy procedure. Go ahead only if you are good with operating multiple systems. Apart from that, this guide won’t touch any of your Windows files, but I highly recommend that you back up all your crucial files because you never know when things go wrong.

Pre-requisites

  • A USB flash drive with a minimum of 16GB of storage space is a must.
  • UEFI Firmware support is another requirement for Brunch to work. It also works with legacy BIOS, but there are a few limitations. You can read them on the Brunch development page.
    1. To check whether your PC supports UEFI or MBR/BIOS, search System Information in the start menu and open it.
    2. Look for the BIOS mode. You’ll find your PC firmware type mentioned against it. Dual Boot Windows and Chrome OS
  • Intel hardware (CPU and GPU) starting from 1st generation Nehalem architecture. Note that Intel first-generation graphics do not work with ChromeOS versions above r81.
  • AMD Ryzen CPU and GPU. Currently supports AMD Ryzen and AMD Stoney Ridge processors only.

Downloads & Requirements

We need the following components for flashing Chrome OS on your Windows PC hard drive.

1. Linux Mint

Dual Boot Windows and Chrome OS

We’ll use the Linux Mint Cinnamon image for dual-booting Chrome OS and Windows 10 or Windows 11 PC. You can use other Linux distros like Ubuntu or Debian too. However, I won’t recommend using them since many users reported that they are facing various errors while installing and booting Chrome OS.

Download Linux MintCinnamon Edition

2. Rufus

Dual Boot Windows and Chrome OS

Rufus is a windows utility that helps create bootable USB flash drives. Here, the purpose of using Rufus is to flash the Linux Mint image on the USB storage.

Download Rufusfor Windows

3. Brunch Framework

Dual Boot Windows and Chrome OS

The purpose of the brunch framework is to build a generic Chrome OS image from an official recovery image. It uses a 1GB ROOTC partition (containing an initramfs, a custom kernel, the swtpm binaries, userspace patches, and config files) and a specific EFI partition to boot from it.

Warning: As Brunch is not the intended way for Chrome OS to work, thus, at some point, some Chrome OS scripts could behave terribly with Brunch and delete data unexpectedly, including Windows / non-Chrome OS partitions. I would highly recommend that you use Chrome OS on a device having less sensitive data.

Download Brunch Framework

4. Chrome OS Recovery Image

Now, it’s time to get the official Chrome OS recovery image. Click on the download button below. When the webpage opens, look for the word rammus. In the recovery column, hit on the latest recovery image to start the download. While writing this guide, the current version is 94, but it may change subsequently.

The reason we chose rammus is that it works on most modern generations of Intel processors. However, I suggest you go through the below list and download the specific image based on your processor.

Intel Processors

  • rammus = Intel 1st to 9th generation processors.
  • volteer= Intel 10th & 11th generation CPUs.

AMD Processors

  • grunt = AMD Stoney Ridge & Bristol Ridge.
  • zork = AMD Ryzen.

5. Shell Script

Finally, download the multi_install.sh shell script, which helps install Chrome OS on a Windows partition. Click on the download button below and press Ctrl + S to save the file.

Dual Boot Windows and Chrome OS

Now that we have acquired all the necessary files – let’s get going to the steps!

Organize Files in One Place

Step 1 – First off, gather all the downloaded files in one place. Let’s consider you have placed all the files in the Desktop folder.

Step 2 – Now, Create a folder named Chrome OS on the Windows Desktop. You can also create it in any other place having sufficient storage.

Step 3 – Using WinRAR, extract the Brunch package by selecting the ‘Extract Here’ option. As a result, you’ll get four files out of the archive. Now, move these four files to the Chrome OS folder.

  1. chromeos-install.sh
  2. efi_legacy.img
  3. efi_secure.img
  4. rootc.img Dual Boot Windows and Chrome OS

Step 4 – Next, extract the Chrome OS recovery image file. Dual Boot Windows and Chrome OS

Step 5 – Upon extraction, you’ll get a file having a .bin extension. Rename the .bin file to rammus_recovery. Now, move the rammus_recovery.bin file to the Chrome OS folder. Note that even if you have downloaded any other Chrome OS image like volteer, grunt or zork, make sure you rename it to their respective name + _recovery.bin. For example, volteer recovery filename would become volteer_recovery.bin, and grunt recovery would become grunt_recovery.bin, and so on. Dual Boot Windows and Chrome OS

Step 6 – Move the shell script file multi_install.sh into the Chrome OS folder.

Step 7 – By this time, you should have six files in the Chrome OS folder. Do note the path of the Chrome OS folder as we’ll need it for performing further steps. Dual Boot Windows and Chrome OS

Flash Linux Mint Cinnamon

Using the Rufus utility, we’ll flash the Linux Mint ISO image on the USB storage. Linux distro installation is necessary because ChromeOS is a Linux-based operating system, and the shell scripts that we downloaded require a Linux environment to work. The steps for installing Linux Mint on the USB storage are as follows.

Step 1 – Plug in the USB storage device such as Pendrive or microSD card and open Rufus utility.

Step 2 – In Rufus, under Device, you shall see the plugged-in USB storage. Here I am using a 32GB Pendrive.

  1. Under Boot selection, select the Linux Mint ISO that we downloaded earlier.
  2. If you are using a Hard drive, tick the List USB Hard Drives option to see your connected hard disk.
  3. Keep all other settings unchanged and now press the Start button.

Do note that flashing the USB storage will wipe out all the data present on it. Therefore, we strongly recommend that you back up all the necessary data before pressing the Start button.

Dual Boot Windows and Chrome OS

Step 3 – When you press the Start button, a popup will appear. Select Write in ISO image mode option and press OK. If you choose DD Image boot, the USB drive won’t be accessible for you to operate in Windows. If you have a legacy BIOS and an old CPU, then DD Image mode is useful. Dual Boot Windows and Chrome OS

Step 4 – Here, Rufus will warn you that it will erase all the data stored on the USB device that we are using to flash Linux Mint. If you have taken the backup, press OK. Dual Boot Windows and Chrome OS

Create Unallocated Space for Chrome OS

Now, we need to create an Unallocated partition using the Windows Disk Management tool. You need to have at least 14 GB or more free space on the hard drive for creating an unallocated partition. I have given 100 GB of space, but you can choose your partition size.

On a side note, let me tell you something. Chrome OS requires partition size in multiples of 22 GB, for example, 22000 MB (22 GB), 44000 MB (44 GB), and so on. But here, you can assign any size you want. Later, before flashing Chrome OS using Linux Mint, we will provide an appropriate partition size.

Let’s shrink the existing drive and create unallocated space. Here are the steps.

Step 1 – Open Windows Explorer and right-click on This PC icon. Select Manage to open Computer Managemen tools. Dual Boot Windows and Chrome OS

Step 2 – Select the Disk Management option from the left. Now, click on the partition from which you want to create unallocated space. I am using an external SSD for space creation. Right-click on the selected drive and click Shrink Volume. Dual Boot Windows and Chrome OS

Step 3 – As discussed at the beginning of this section, I will create a 100 GB (100000 MB) partition. Press the Shrink button to proceed. Dual Boot Windows and Chrome OS

Step 4 – Now, in the disk management, you will see that the unallocated space is separated from the selected drive and marked in black. Dual Boot Windows and Chrome OS

All good so far? Now we have completed all the required operations on Windows OS. Let’s boot the Linux Mint Cinnamon image from the USB flash drive.

Boot Linux Mint from USB Storage

For Linux Mint bootup and Chrome OS installation, we will have to perform a few operations in PC BIOS.

Step 1 – Shut down the Windows PC if running. Boot into the BIOS menu. For doing that, start your PC and continuously press the F2 or DEL key on the keyboard. Your PC might have a different key set for booting into the BIOS. Refer to the below table and find out the right key.

Brands BIOS Key
Acer F2 or DEL
ASUS F2 for all PCs, F2 or DEL for motherboards
Dell F2 or F12
HP ESC or F10
Lenovo (Laptops) F2 or Fn + F2
Lenovo (Desktops) F1
Lenovo (Thinkpads) Enter + F1
MSI DEL for motherboards and PCs
Origin PC F2
Samsung F2
Sony F1, F2, or F3
Toshiba F2

BIOS Menu keys for various Brands

Step 2 – In the BIOS, navigate to the Boot tab and disable Fast Boot. Also, check if you have CSM (Compatibility Support Module) option. If present, set it to Disabled because we are using a UFEI mode. If you want to use Legacy mode, you can keep the CSM option enabled.

Step 3 – Now that we want to boot Linux Mint instead of Windows, we need to change the boot order. Move USB Storage at the top so that BIOS will boot our USB flash drive. Brands BIOS Key Acer F2 or DEL ASUS F2 for all PCs, F2 or DEL for motherboards Dell F2 or F12 HP ESC or F10 Lenovo (Laptops) F2 or Fn + F2 Lenovo (Desktops) F1 Lenovo (Thinkpads) Enter + F1 MSI DEL for motherboards and PCs Origin PC F2 Samsung F2 Sony F1, F2, or F3 Toshiba F2 BIOS Menu keys for various Brands

Step 4 – Navigate to the Security tab and look for Secure Boot Control or a similar option. If enabled, change it to Disabled. Without disabling the secure boot function, you can’t boot the Chrome OS even after a successful installation. Dual Boot Windows and Chrome OS

Step 5 – Finally, press the F10 key to save the changes and exit the BIOS. Your PC shall restart, and you will see the following Linux Mint Menu. Press Enter to proceed. Dual Boot Windows and Chrome OS

At this point, you should have entered into the Linux Mint Cinnamon OS.

Install Chrome OS

Step 1 – Once you see the Linux Mint interface, connect your PC to the Internet using ethernet cable or Wi-Fi. The Chrome OS installer requires an active internet connection to fetch necessary libraries and dependencies.

Step 2 – Now, double-click the Computer icon on the desktop and navigate to the drive where you have kept the Chrome OS folder. Dual Boot Windows and Chrome OS

Step 3 – Right-click on the blank white space and select the Open in Terminal option. A terminal window pointing to the Chrome OS folder shall open. Dual Boot Windows and Chrome OS

Shell Commands

Step 4 – Enter the following command in the Terminal window.

sudo sh multi_install.sh Dual Boot Windows and Chrome OS

Step 5 – The installer will ask you whether to download the required files and continue the installation. Press y and hit Enter key.

Step 6 – Following the installation, a window will appear, and it’s nothing but a Linux disk partition tool GParted.

  1. If you have multiple drives connected to your PC, then make sure that the correct hard disk is visible at the top right side.
  2. Select the entry named unallocated.
  3. Click on the plus icon located at the top left to create a partition.
