Jbusch,
I am not sure what you mean about there not being any other choices available?
Did you follow this tutorial to the "t"
https://www.symantec.com/connect/articles/creating-pxe-boot-image-ghostcasting-ghost-solution-suite-3.
How is PXE not working?
Do you receive a DHCP retry error? This means you are missing network drivers, please see the below documentation.

Does your machine just boot to windows? Check your bios boot options and verify it is set to pxe or manually select f12 during boot and boot to the network.
Any other errors seen?
