I paid a per-incident AppleCare call and they said they do not support non-internet recovery anymore and I have to take it to a care center to reinstall the OS for me(in the post laptop era, owner has no control of OS installation any more). On top of it, I just realized that I can't reinstall OS X even with wifi using the recovery console, it led to the screen saying 'Could not find installation information for this machine.

I want it to be possible from a placewith out internet as well. Experimentation led to instability and the fastest way to get back is to reinstall the OS to a fresh start. recently, I was testing my client's app on it and made lots of changes to the OS settings. The main purpose of the Macbook Air is to use it on the road when i travel.

Is this possible on these newer machines? What are the steps? I want to reinstall the OS on the laptop without an internet connection.
