Norton Ghost is the program I use at work. 'Ghosting' is a term derived from Norton, there's actually no such thing (you know, like everyone calls it a 'Hoover' when thats just the make, it's really a Vacuum, or people call it a 'Biro' but it's really a Ballpoint pen etc.)

It's pretty simple to use, you can probably download it somewhere. You can create a boot floppy disk using the wizard then using that it boots up and loads into a very simple GUI with step by step instructions.

Hope that helps.
