Your question makes no sense.
Debian is an entire operating system and does not run "on" another operating system.
If you have something like VMware installed on your NT 4 system, then Debian can run in that.
Other than that, you would have to set up your system to dual-boot between Debian or NT to get them both on the same system.
Just slapping Debian on there would likely overwrite your NT or at least make it very difficult to get back into.

That message is actually from an email address harvesting spambot of some sort. We've been seening these on the list for the last few weeks. They are usually very general, like: "My printer doesn't work. How can I fix it?" This one is just plain stupid, or beyond.
