Install Windows From Portable Hard Drive

I want to install Windows from a USB portable hard drive. This needs to work on virtually any computer for a computer repair shop. I will have different versions of Windows, exp: 2000, XP, XP Pro, on the portable hard drive. I do not need to know how to slim down Windows to fit on a CD. I need to know how to set up the Hard Drive, for Ex: do I put the Windows Versions as ISO, maybe a GUi to Choose from Multiple Installs. Again this has to work on any computer, not just one's that boot USB. Maybe the answer is a CD that Install external hard drive drivers then installs Windows? I don't know.
