Bart PE is a modified version of windows XP that boots off and runs off a CD.  When you create a Bart PE CD, you can choose what software is installed on the installation.  Of course you have to have copies of the software you would like installed to create the CD.  The whole reason for the CD is to get Norton Ghost to work with your USB drive.  Creating a DOS usb boot disk for Norton Ghost is very challenging and may be impossible depending on the USB drive you have. 

Once you create the CD, you have to boot your server off the CD and use Ghost to image the OS partition.  Automating that would be rather challenging.
