Hi, the time has come to upgrade to Lion! I am still running Snow Leopard on my Macbook Pro 2011 and now I want to get Lion, but i have a problem. I want to do a fresh installation of Lion. My procedure to do so would be: 1. Download the Lion OS from the AppStore. 2. Create a bootable usb drive with Lion on it. 3. Plug my drive in, restart my Mac (holding down the option key) 4. Install Lion. Is that correct or did i miss anything? And, is it possible to format the harddrive before installing Lion? Thanks!
