If i try with an original OSX ML DVD, would i have a chance to install it, without having already installed Snow Leopard ??
I think it is very easy if you have some know how but very difficult if you're a beginner
read the first page and try it :-)
If no OS has been installed, yet, now is the time to do so. After mounting your Mac OS X Install DVD, ISO, or downloading a ESD from the App Store, selectRetail DVD installer
