It will be a mkisofs issue. On the original cd (and now also your copy)
will be a *floppy* image file that contains the boot code. It's weird,
CDs mimic booting from a floppy! I've made boot CDs using the following
mkisofs command (after placing the boot floppy image in /tmp):
mkisofs -v -U -R -b /tmp/fd144.img -c /
You will want to modify this to suit your env. Note that the floppy
image has to be *part of* (i.e. a file within) the filesystem you are
writing to the CD!

To make a bit for bit copy of a CD it is probably easier to extract
the CD image directly to a file (avoid mkisofs all together):
dd if=/dev/cdrom of=image.iso
then cdrecord image.iso directly. You can test to see if your dd
worked correctly with:
mount image.iso -r -t iso9660 -o loop /mnt/iso
This lets you browse (but not change) the image before you burn a CD.
