Before we get into the tutorial, it would be good if you are aware of using multiple operating systems on a single PC. But nevertheless, we have specified every step in detail so that you don’t face any problems.

Also, it is advised to backup all your important files and data from your PC because you don’t know when things might get worse.

So, let us begin with the guided steps to dual boot Chrome OS and Windows 10 on your PC.

Hardware Requirements

  • UEFI boot support in the BIOS
  • Intel-based CPU and GPU (AMD CPUs might work as well)
  • A USB flash drive with at least 16GB of storage.

Downloading Prerequisites

1. First, we have to download the Linux Mint Cinnamon image. Choose between the 32-bit or 64-bit based on your system architecture.

4. After this, we have to download the Chrome OS recovery image. On the website download the latest recovery image. Note that you will need to download the Rammus recovery image if you are using 4th-gen Intel CPU or newer. For AMD CPUs, download the latest recovery image named Grunt.

5. Now, we have to download the framework named Brunch which was developed by sebanc. This framework will help us to create a generic Chrome OS image from the official recovery image. Download the latest stable build by clicking on the tar.gz file under the assets tab.

6. At last, download the script multi_install.sh by Kedar Nimbalkar. This script will let us install Chrome OS on our windows partition which we will create later in this post. Press Ctrl+S to save the script file.

Now, we have downloaded all the required files and we are ready to be being with the installation.

Preparing Files for Installation

1. First, Create a folder named Chrome OS on your hard drive and move the multi_install.sh script into the Chrome OS folder.

Creating the Partition

In order to install Chrome OS, we need to create a partition on our Drive.

A single partition may work for a lot of you guys but we recommend creating two partitions– one of 100GB and other of 60GB of size. The sizes of these partitions are not specific, you can choose the sizes based on your preference.

We are only going to use the bigger partition of 100GB for installing the Chrome OS. And the smaller partition is used for mounting the Chrome OS image file. So, after the installation, the smaller partition of 60GB is free to use on Windows.

1. Press the Windows Key on the keyboard and search for “disk partition”. Then, open the first result.

Dual Boot Chrome OS and Windows 10

Now, We have successfully installed the Chrome OS on the windows partition. But, we need to make the Chrome OS bootable during the startup. For this, we are going to use the Grub2Win application.

2. Complete the basic setup by keeping everything to default. Now, click on the “Manage Boot” Menu button.

Troubleshoot Common Issues

The Commons issues that many people get are “Not enough space to create image file”, “failed-to-get-canonical-path-of-cow” or “GtkDialog mapped without a transient parent”. If you are getting these problems, it recommended to follow our partition guide. This way you can get rid of these issues.

As of now, we have no information about why these errors are happening. But, we will soon update this article along with the solution.

Also, the other common issue is that after the few boot-ups, the Grub2Win interface does not show up and the PC directly boots into the Windows. This can happen when Windows overrides the EFI interface.

The Quick solution for this is to keep pressing the boot key while the PC is booting up. After this, you can select the Grub2Win EFI interface. And choose Chrome OS from the boot options.
