Hi, I tried installing mac snow leopard from a USB stick after learning the installation through several forums. To my bad luck the laptop is shutting down in the mid of the installation and I have lost my leopard as well. Can some body please tell me how should I install it completely. Also, I made my thumb drive bootable on mac and windows is not detecting my drive. Can some body please help me in formatting using windows. Thanks an regards. Regards, Ravi.
