[QUOTE="muaaman, post: 1631877, member: 306742"] If nothing is pressed soon, pressing the power button leads to a grey screen with a prohibition sign on a Macbook Air 13'' running Mountain Lion. Attempt 1: Pressed Command+Option+R Internet recovery on compatible network -> leads to this error: apple.com/support -3400F Attempt 2: Pressed D Internet recovery on compatible network -> leads to this error: apple.com/support -3400D Attempt 3: Pressed Command+R Prohibition sign. Resolution input would be greatly appreciated. [/QUOTE]
