Adding a Boot Image

This example builds on the Burning a Disc Image example by adding code to include a bootable image in the boot section of the disc. The bootable image connects to the file system object that is written to disc. Once attached, the rest of the burning process is identical to the basic burning procedure. The boot image provides system startup using the CD or DVD disc drive.

The example hardcodes the path to the bootable image. Be sure to change the path along with other hardcoded values as appropriate.


' This script burns a boot image and data files to disc in a 
' single session  using files from a single directory tree.
