How to force Win 2000 Pro to install in a specific directory? I never get a question as to where I want to install the OS. I've tried to reinstall W2K Pro in my Windows directory and it keeps going to a clean install in WINNT. How do I make an upgrade installation instead of clean and force it to go to WINDOWS or some other directory or drive? How do you run the upgrade booting from the CD and picking the directory?
