You don't "make an .iso image bootable". An ISO image is just that an
"image" of a CD. Normally, it's either bootable or it isn't. Now, you
can make a bootable CD ISO image. Which is effectively an ISO image of
a bootable CD. Think of the ISO image file as everything necessary to
recreate the CD.
For more information on creating ISO images, take a look at the man
pages for "dd" and "mkisofs".
With cdrecord, creating a CD from an ISO image is normally as easy as:
cdrecord dev=0,1,0 /path/to/image.iso
You will most likely need to change the "dev=0,1,0" above. The proper
value can normally be found by running:
cdrecord --scanbus
and then using the 3 numbers listed before your burner's entry in the
output. These are the SCSI bus, SCSI ID, and SCSI Lun of the device
(IIRC).
