How to create a recovery disc in windows 7
Understand what this disc does.
In order to create an installation disc, you'll need your windows 7 product key. If you purchased a prebuilt computer or laptop, you can usually find the product key printed on a sticker affixed to the bottom of your laptop or on the back of your tower.
It may be included with your computer's documentation. If you purchased windows 7 from a store, the key will be in the dvd case or in your confirmation email.
