Ok, there is a new EFI update for my MBP, 2.7 I believe it said, so I hit download and install from the updater and it downloads and then the computer shuts off and makes a loud BEEP and then boots the the apple logo, with the loading bar under it, but doesn't load and then turns off, goes to the screen again and then keeps repeating this.

I tried it twice with no luck.

Help!

Hold the power button when you turn it on and see if you hear the loud beep and see if it starts after you hold the button. If not try a pram reset and and smc reset that.
