Software Updates, Restorations and Utilities Repairing or Reinstalling the Operating System The OS CD included with your notebook can be used to repair or reinstall the operating system. Both operations may take one to 2 hours to complete. ■ Repairing the operating system preserves your data and settings. ■ Reinstalling the operating system deletes all files on the notebook. After the operating system has been reinstalled, all device drivers must also be reinstalled. HP recommends that you try to restore your system by using the System Restore utility before you consider repairing or reinstalling your operating system. For restoration instructions, see "Backing Up and Restoring Data" earlier in this chapter. If a System Restore restoration fails to restore functionality, first try to repair the operating system. If the repair procedure does not restore functionality, you may need to reinstall the operating system. Repairing the Operating System To repair the operating system without deleting your personal data: 1. Connect the notebook to external power and turn on the notebook. 2. Immediately insert the OS CD (included with the notebook) into the optical drive. 3. Press and hold the power button for 5 seconds to turn off the notebook. 4. Briefly press the power button to start the notebook. 5. When prompted, press any key to boot from CD. (After a few minutes, the Welcome to Setup screen is displayed.)
