Look at this KB:

so in the capture/distribute image task it will ask you what imaging engine you want to use. There is no ghost selection.

check the imagetools.ini file in the express share. it should look like this.

; Modify this .INI file to integrate the new imaging tools in the Deployment Solution.
; The following is a list of the supported preboot environments and their abbreviated names.

This is direct from the DS 6.9 admin guide, page 222:

Important
Deployment Solution does not include the Ghost executable or a license to use
Symantec Ghost. You must provide a copy of the ghost.exe and/or ghost32.exe imaging
executable to enable this support.

Customers currently using Ghost imaging solutions have the option of copying the Ghost
executable to the Deployment Server to enable Ghost imaging from the Create Disk
Image and Distribute Disk Image tasks.

To add support for Symantec Ghost:
1. On the Deployment Share, create a folder called ghost. Copy ghost.exe (for DOS
support) and/or ghost32.exe (for WinPE support) to this folder.
Symantec Ghost is now available for selection in the Create Disk Image and Distribute
Disk Image tasks. A configuration file called ImageTools.ini, located in the root of your
Deployment Share, contains settings you can change to customize the behavior of
Ghost.
