Problem
When using Boot Camp Assistant in Leopard (OS X 10.5) or Snow Leopard (OS X 10.6), you arrive at the stage to download Windows drivers and the below error message is received.
Solution
You will need to install Windows drivers from your original Mac OS X installation CD. Boot Camp Assistant will no longer work for downloading drivers for anything earlier than Lion (OS X 10.7).
Quit Boot Camp Assistant and run it again. When you get to the “Select Tasks” stage, deselect the first check box.
