Please help, I tried to install bootcamp and it didn't work, and then when I restarted and pressed alt to choose mac, it wasn't there. I don't have mac or windows on my mac!! I inserted the lepored disk to install and there is no hardrive to install it on!!! Help me please. Using new aluminum macbook 2.4ghz i ran the windows setup - it said it worked but then there is no windows to choose from what should I do?
