Unduh ISO Chrome OS, https://chromiumdash.appspot.com/serving-builds?deviceCategory=Chrome%20OS
Unduh Brunch terbaru, https://github.com/sebanc/brunch
Buat folder baru dengan nama Chrome dan ekstrak keduanya kedalamnya
Siapkan partisi untuk menginstall Chrome OS dengan format ext4, gunakan aplikasi GParted
Masuk ke folder Chrome dan buka terminal
$ mkdir -p ~/tmpmount
$ sudo mount /dev/sda3 ~/tmpmount
Sesuai dengan partisi yang digunakan, contoh menggunakan sda3
$ sudo bash chromeos-install.sh -src chromeos_14816.131.0_rammus_recovery_stable-channel_mp-v2.bin -dst ~/tmpmount/chromeos -s 64
64 adalah ukuran file ISO untuk Chrome OS, bisa diganti sesuai kebutuhan
