ghost boot wizard

i new to ghost so bear with me. im trying to make a bootable cd to connect my toshiba satellite s3000 laptops to the ghost cast server. im using ghost boot wizard to create the image, but every time i burn it and try to boot from it screen shows “boot failure” i know i have the right dos driver because i can make a bootable flash drive but this will not suffice because i have 30 laptops need to image more than one. here are the steps im taking. am i missing something?
1. symantec ghost boot wizard
2. network boot package
3. load ndis driver (browse to driver)
4. use pc-dos
5. ensure program points to ghost.exe
6. enable dhcp
7. save file
8. burn iso using cd burner xp

thanks
