Hi Guys, i have a MBP that i have brought to have a HD change and they put me a 500gb Disk but the DVD disk with Snow Leopard that i had is scratched and didn't work... i called an apple store to know if they had a DVD set with Leopard and they say that they do not hold any physical OS X in stores anymore adn that everything has to be ordered via Apple.com... i cant wait so what do i do? I tried a couple of things that i have found over internet but they dont work and i cant seem to find anybody that has a Snow Leo ISO to give me... Also, at the beginning the DVD boots but then when installing after 5 minutes it stops cause of errors ... the last time i have tried to make it boot from another USB external disk cause i thought it was my DVD player but now i UNABLE to make the machine boot from the internal DVD player ... it always shows the ? and stays like that forever.. what do i have to do? It's impossible that my machine is acting like that... i was always been able to boot at least with my DVD player... I tried all kinds of keyboard combinations like "C", "X", "command" etc etc... What do i do??? thanks William!
