I want to install Windows XP and will prob give it 25GB space. I don't have anything to back it up with, so what do I do? Can I proceed w/o backing up?
You can, but if you do you are foolish, and better expect the worst just so you aren't disappointed if something goes wrong. Buy an external and don't worry about it.
Zip drives were the stuff back in the day
I remember when I got mine and thought it was the greatest thing
OP, you should have a backup strategy regardless of your intent to install Windows, however I would never recommend doing anything with a partition or Boot Camp without one
Unless of course you have nothing on your drive that is important to you
This forum is littered with threads from people who have lost everything without a backup
