How to create recovery disk?

I am using an acer desktop, with Windows XP?
How would I create a posterior up recovery disk?

Answers:

I just bought one myself. Had this same problem. Get some DVD not cd disk to do this on! Go into programs and into the Acer subprogram within the middle of the pull up catalogue. Click on that it brings up another list. Click on Acer eRocevery Management third item is create user backup. Like I said use DVDs it will merely take 2 disk, CD's will involve 14 or so.
