So if you have the dagent service running (this is good) then it is waiting for your ghost server to assighn a job to it. This boot disk you have made is a ghost agent boot disk if you will.
If you wanted the ghost GUI to load you will want to use the other boot disk creatror, It is confusing we have 2 boot wizards,
- Standard tools loads the ghost GUI when booted (makes a traditional ghost boot disk)
- agent/automation boot disk. Loads the agent and talkes to the console. (jobs are then run from the console)
Video on standard tools (the download used to be from fileconnect.symantec.com but it is now mysymantec.com

Video on making and deploying a basic backup image with a client booted to automation with the agent running. (could be PXE, USB, DVD or automation folder booted)
