I would like to condense my bootable CD and DVD collection onto a SSD.

I have managed to write two Windows OS Installers to the SSD and successfully installed Windows from the SSD to 3 Different machines, but I haven't enough experience to write the scripts necessary to be able to over write a bootable partition with new OS installer without conflict. 

Does anyone have any experience with this?

The format and reinstall time is so much significantly faster that my work time has been cut in half. I dont want to have to buy a separate ssd for each flavor of Windows
