What am I doing wrong?

Ok, so I read the FAQ (I read a few FAQ's, actually) and I got myself a couple of CDI image files (games)...

So I ####t up DiscJuggler (although, I have 3.50.799 as opposed to 2.0 in the FAQ - there are subtle differences). File-->New. CD Pre-mastering to CD Recorders.

On CD Recording tab-->Advanced tab, I select Mode 1 (CD-ROM). On Action pull-down dialog, I select Write.

On the Explorer tab, I drag the CDI image file to the "open session". It asks me if I want to treat the specified file as a CD Image. I say no (saying yes makes it a CD-DA Session/Audio track).

The ####t button is greyed out unless I also ##### the "Overburn CD" option. So I ##### this and ####t the burn. What I'm left with on the CD is the exact same file I have on my hard drive - a large CDI image file.

Needless to say, this does nothing when I pop it into my DC. Inserting the Bootloader disc first also does nothing, as it, too, is also a CDI image file on the disc (which I also followed the instructions in the FAQ on the site to create).

So what am I missing? Someone please help me.
