After installing chrubuntu on my c7, I decided to put it back to factory and give crouton a try so that I could run both chrome and crouton at the same time. I created the restore usb stick in Linux then threw it in the c7 at the ‘missing or damaged’ note. My c7 gave me “An unexpected error has occurred” when I tried to run it!
- Turn off chromebook
- Remove battery
- Press power button to drain anything else out of the system
- Put battery back on
- Power on
Boom – now your c7 is back to normal!
