Now I know I did it wrong, but here's the problem in a nutshell.

Windows XP install is hung up at "Installing Windows" Setup will complete in 39 minutes"

But I can't get the install to stop or get to a command prompt, safe mode, or anything.  It just wants to persist with the install, but install is hung up. 

Can I still save my data at this point?

How do I get out of the install?
