Hello-

I can't get this to work. I downloaded the file, unzipped the file, put all the unzipped files onto two separate, freshly formatted USB drives, and am not having any luck.

With one USB stick, when I hit F11 and select it, it just boots straight to Windows. With the other USB stick, I get an error that says "An operating system was found........" and when I hit any key to continue, it boots to Windows.

Is there an alternate way to reflash the MAC address or can you provide me with some guidance on how to get the system to boot on the USB drive with the files on it?

Thanks!
