Start up from your installation DVD holding down the "C" key. Go to the second screen pull down menu to Utilities > Disk Utility. Select your drive and format it and give it one partition. Now you can install your system.

Insert your system installation disk and restart holding down the "C" key till the Apple logo appears. If this fails, disconnect the hard drive and do the same thing. Let us know your results.

I prefer to walk into music station in jersey city they are the only ones that actually have a store and can do the work while you wait. I don't trust the guys that just have a website and you send it to there house where it can catch bed bugs or get knocked over.

there store is in New jersey there site is jerseycityrepair.com

For EFI password : warning ! qwerty keyboard

If you have no password just one solution : The old trick of changing RAM level does not work anymore. Only an authorized Apple Service Provider can reset.
