When we buy a new notebook, we are advised once to make a DVD system back up. Why? This is important, because if (hopefully not) one day we die total OS / can not live, we can make recovery backup system with DVD system without having to bring it to the service.
Here's how to make it
A. Click the Windows button in the lower left, then your search by typing the word "back up"
2. Click the application that says "back up" then you will be brought to the windows of this page
Control Panel \ All Control Panel Items \ Backup and Restore
3. Provide a blank or a blank DVD as much as 2 pieces. This DVD is useful to keep a back-up your system.
4. Then follow the instructions there to enter a DVD and burn it there
DVD is used for recovery if your OS is damaged, so you do not need to go to a service or to the HP Service Center, but you can do revocery themselves by entering it into the DVD back up your ROM :)
But, there are also important to do, is to always put our critical data on the drive that is not our place to install the OS drive, because if one OS is damaged, the data we will be safe and secure.
