Create a CD Boot

I read this on a news group

Create a Directory like:
mkdir -p myinstallcd/dosutils /autoboot

Copy the image to where you want the image to be:
cp bootdisk.img myinstallcd/dosutils /autoboot

Now create ISO of the image and make it bootable.

mkisofs -b dosutils/autoboot/bo otdisk.img -c boot.cat -r -o myinstallcd.iso
myinstallcd

Finally, burn the image:
cdrecord -v speed=16 dev=0,0,0 -data myinstallcd.iso
