Was browsing this morning and all of a sudden got a screen that said "Chrome OS is missing or damaged. Please insert a recovery USB stick or SD card." After booting up an old Chromebook and searching a bit I tried some less desperate measures and nothing worked so I downloaded and installed the Chrome recovery app and ran it according to the directions. I installed on a usb stick and after trying that I got the "unexpected error during recovery" message. So I installed it on an SD card and same thing happened. All google has to say at this point is 'call manufacturer'. Are there any other options? Thanks!
