Reinstalling and Updating Software
You can use the Recovery CD or DVD to recover the original software build for your
computer.
The Recovery CD or DVD also provides Windows drivers specific to your computer to
configure a custom system. You can find drivers in these locations:
• On your computer’s hard drive under C:\hp\Drivers.
• On the Recovery CD or DVD under \hp\Drivers.
• On the HP Business Support Web site (www.hp.com/go/bizsupport). This Web site
contains the latest updates of software drivers for different operating systems.
To recover the factory installation of your hard disk
You can use the Recovery CD or DVD to reinstall the original factory software on your
computer’s hard disk. You can also use the same process to create a Utility partition on a
new hard disk. The hidden Utility partition contains the e-Diagtools diagnostic tests.
