I am using Ubuntu 20.04 LTS. I want to use Chrome OS alongside my Ubuntu. All the videos I have seen include involvement of Windows 10 and Linux Mint and those are about triple booting. Can someone show me the exact way of installing and dual booting ChromeOS with Ubuntu only?
I installed Phoenix OS alongside my Ubuntu and set that Phoenix OS as default operating system in grub customizer. Now it can't detect my Phoenix OS . Also I can't access my Ubuntu. So is their any other way to access Ubuntu and change the grub customizer so that I can change my default operating system back to Ubuntu from Phoenix? Please help!???
