Hp laptops dont come with recovery disks anymore but if you see in your D drive.Your drivers and installation files are preloaded there.In case of a Format, you can install it from the D drive. And if u still insist on having a Disk ( just to be on the safer side )

U need to go to Programs menu, there you will see
Recovery Manager ==== > Recovery Disk Creation. Follow the steps and make sure 1st that u have a few DVD`s handy.
