I have searched with no luck to solve this problem. I managed to copy tto the Snow Leopard image from the disk to the usb stick. I also copied the NBI file onto the 2gb stick. When I boot up the mini the Apple logo comes on followed by the spinning wheel which freezes after two minutes. I never get to the progress bar. I ordered another Snow Leopard dik from Amazon to make sure the disk wasnt corrupted, followed the steps in the guide, and got the same problem. I am on a03 bios. Any assistance would be appreciated as this process has stretched for a week on and off.
