MacBook air won't boot
I tried all the steps but the only thing that the macbook does is a little "clic" near the power button after I pressed it to turn the macbook air on. The light comes up for a few seconds, then the clic, then the light off.
I tried to boot from an external usb drive with a Snow Leopard installed, but it was impossible since no boot process appears to work.
Any ideas? Thank you
