The required downloads

1. First, download the Linux Mint Cinnamon image. Depending on your PC's architecture, you can choose a 64-bit or 32-bit build.

2. Next, download Rufus to be able to flash Linux Mint Cinnamon on USB.

3. After that, download the official Chrome OS recovery image. Open the web and search for rammus. Now, click on the latest recovery image (right now, it's 80 , but it may change in the future). Rammus is the recommended image for devices with Intel 4th and newer CPUs. However, if you have a 3rd generation Intel CPU or higher then download the latest image for samus. And if you have an AMD CPU, you can try it out by downloading the latest grunt image .

4. Now, download the most important file: Brunch. It is a framework built by a developer named sebanc.

To download the file, find the latest stable build and then click Assets. Now, download the tar.gz file.

Create partition

While creating a single partition works for many users, some people experience problems during the installation. So, to avoid any errors during the installation process, you can create two partitions - one with 100GB and one with 60GB. This is not a required capacity requirement and you can reduce the space according to your preferences, but if you have a comfortable space then follow this structure to install seamlessly.

Remember, you will only use the 100GB partition to install Chrome OS. The next 60GB is needed to mount the image file. So once the installation is complete, you are free to use the 60GB partition for everything on Windows 10.

1. Press the key Winonce and search for disk partition. Now, click on the first result.

2. Here, right-click on the last drive and select Shrink Volume.

3. Now, enter 160GB if your hard drive has a large capacity. Then click Shrink.

Troubleshoot

If you're getting an error like 'Not enough space to create image file', 'failed-to-get-canonical-path-of-cow' or 'GtkDialog mapped without a transient parent' , the article recommends following the structure partition in the example.

In addition, many users have complained that after a few initial starts, the Grub2Win interface is not displayed and the computer boots directly into Windows 10. That happens because Windows is overwriting other EFI interfaces. There are solutions like fixing GRUB through Linux Mint, but for now the article doesn't go into it.

For a quick solution, you can press the boot key (F7, F8, F9, etc.) during the boot process and from there, you can choose the Grub2Win EFI interface. After that, you will be given the multi-boot option. It's troublesome to press the boot key every time it boots, but for now, it's a quick and effective solution.
