Reinstalling and Updating Software
You can use the Recovery CDs or DVDs to recover the original factory software for your
notebook.
The Recovery CDs or DVDs also provide Windows drivers specific to your notebook to
configure a custom system. You can find drivers in these locations:
• On your notebook’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 CDs or DVDs to reinstall the original factory software on your
notebook’s hard disk. You can also use the same process to create a larger Utility
partition on your hard disk, or to create a Utility partition on a new hard disk. The hidden
Utility partition contains the e–Diagtools diagnostic tests and stores hibernation data for
operating systems that don’t provide hibernation.
CAUTION
This procedure formats the notebook’s hard disk drive and erases all data on the

is complete.
