Yes Chrome OS flex is built off of the linux kernel so to activate linux you have to go to settings about my chromebook devoleper options and install linux and soon you’re done go to the github page GitHub - balena-io/etcher: Flash OS images to SD cards & USB drives, safely and easily. and then copy the text through the termanial and do control shift v to copy and paste and then soon put y and your done
