Installation

I am trying to install m0n0wall on a CF card, but every time I write an image to the card it shows as blank.  I have tried using both physdiskwriter and diskimg to write the image.  I follow the instructions exactly as they are listed, but I am unable to boot off of the card.  Any suggestions?

It's not a format readable by Windows so it won't show anything. It's likely writing fine. What happens when you try to boot off of it?

Thanks for the reply.

When I boot off the card, it tells me that I need to insert a bootable device or drive.
