Rammus is the recommended image for devices with 4th generation Intel CPUs and later. However, if you have a 3rd generation Intel CPU or higher then download the latest image for samus.

Create partition

While creating a single partition works for many users, some have encountered some problems during the installation. So, to avoid any errors during the installation, 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 preference, but if you have a comfortable space then follow this structure for a seamless installation.

Remember, you’ll only be using a 100GB partition to install Chrome OS. The next 60GB is required to mount the image file. So, after the installation is complete, you are free to use the 60GB partition for everything on Windows 10.

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

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

Also, many users have complained that after a few initial boots, the Grub2Win interface doesn’t show up and the computer boots directly into Windows 10. It happened because Windows is overwriting other EFI interfaces. There are solutions like fixing GRUB via Linux Mint, but for now the article is not going into it.

To do the 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 a 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.
