Need help with adding my batch file to startup.

I'm building a x86 Windows 7 Enterprise PE disc.

I have it set perfect as I want, bare bones, drivers installed, everything.

My only problem is that I want to add a batch script to the start-up of my disc so that it pops up as soon as the boot disc hits the desktop. I know I can have the file just sit on the desktop and click on it manually, but is there a way that I can get my batch file to start up automatically when the disc boots?

This is what I have so far in my script:

net use x: \\gto\image\

START "Ghost32.exe" x:\\gto\image\ghost32.exe

I am trying to have the batch file reach my server (requires username and password), and then start up ghost32.exe from the location. Is this possible with putting a batch file in the startup of my boot disc?

Thanks.
