Long story short, my original DVD's to restore my macbook 2007 are scratched up pretty bad. Me being dumb didn't take into consideration that my disks were scratched. Well, i went to install it and i seem to keep getting errors when i install my macbook fresh. Errors such as "Repeated install attempts result in different "Installed Failed" exclamations such as; "could not validate the contents of 'EssentialPackage' or, 'AdditionalSpeechVoices' or, 'BaseSystem'. I've tried each of the thee install methods starting with "upgrade" and ending with the most drastic method, "clean install". Nothing works, even after paring the installation package to the bare minimum, i.e; no additional, languages, no X11, no additional fonts, etc. So I decided to order a 10.6 Mac OS x snow leopard disk from Apple...finally got it today and put it in to start a fresh install because i have no mac os x on my laptop anymore. and i STILL get errors but different ones, saying cannot complete this installation etc. Anyone know how to fix this or whats wrong...?
