Most manufacturers do not include disks with their systems. Instead they now have a recovery partition which takes the place of disks.
To find out if there is a recovery partition on your computer
Start>All Programs>HP Tools>HP PC System Recovery.
You could also tap the F10 key repeatedly when booting the PC.
Follow the on screen instructons.
After you get your computer set up with all the Microsoft updates and security programs MAKE RECOVERY DISKS.
Instructions for this can be found here http://www.pctechbytes.com/hp/recovery-creation/
It will probably take more than one disk so make sure you number each disk when you take it out of the cd tray.
Put the disks in a safe place, do not lose them. You can only make 1 set of the disks. What I suggest is that you copy the disks at least one time. If the original disks become scratched, broken or unusable you will have a back up to use.
