I have trying multiple was to get Windows 7 installed on my Mac Min server(Early 2011 (it not running the sever software) with lion 10.7.3. Whenever I start bootcamp It has the USB option to create the windows 7 install using the USB. I have tried using different USB's 4GB to 8GB in size I have formatted them as Fat32with a MBR. left them unformatted gut cannot get bootcamp to cooperate. I decided to see if I could replicate the issue on a different mac and can I don't get the option with my brand new IMAC , MACBook, or my other MAc Mini(Mid 2010). So my question what is the magic needed to get bootcamp to use the USB.
