The driver disk image file contains a complete file system.  It's
probably either VFAT (Windows/DOS) or Ext2/3 (Linux).  The standard
CDROM file system is ISO 9660.  If you use the standard method of
writing CDROM's using Roxio, it probably considered dd.img as a regular
file and wrote it to the CDROM as part of an ISO 9660 file system.  So
you end up with a file system within a file system which isn't what you
want.  Usually hidden in the menus somewhere is an option to write a
file as an image and not create a file system for it.  The software will
probably look only for *.iso files by default, so you will have to make
it show all files to select the dd.img (or rename it dd.iso).  If you do
it correctly and dd.img contains a Linux file system, then Windows won't
be able to read it after you burn it.  

After burning the image file, the next complication is if the installer
will read it.  Under an installed Linux, there is usually no problem
mounting any of the three file systems (ISO, VFAT, EXT2/3) written to a
CDROM.  The question is if the installer will recognize anything other
than a standard ISO during install.  You'll have to try it and see.
