A couple of months ago I got it to run on linux good but i wanted to go back to chrome, but while i was messing around with ubuntu, i never installed it just using the live mode, i accidentally deleted some of the chromeos.
More recently, I got the recovery usb and everything, but when i get to the unplug/take out external devices part, i unplug the usb with the recovery stuff on it, and then it goes back to the os verification is off or the chromeos is missing/damaged part. It is a Samsung Chromebook 3,
