Hi guys, (first post haha) Ummm Im having some major issues installing SL on my macbook white (luckily I backed it up). I inserted the install disc in leopard and the installer booted up etc. It seemed to be going fine until it rebooted. When it rebooted it went into the OSX installer - i clicked the accept agreements etc again. Pressed install and my disc didn't show up. I looked in disc utility and it wasn't there either however when I went into system profile under Sata it showed the hdd. I am really confused - 1. as to why it loaded the osx installer again and 2. why has my disc not displayed. As it wasn't worse... Now my mac wont boot automatically off of the HD. I have to hold down the option key and select Mac HD else it wont boot. When it does boot it just goes back into leopard 10.5.8.... I dont understand... All I want to do i to be able to upgrade my mac to snow leopard. The internal HD is a 300GB WD HDD encase you wondered. Any help would be appreciated.
