HP ProBook 4420s User Manual

Using a Windows Vista operating system DVD (purchased separately)
If you are unable to boot (start up) your computer, you must purchase a Windows Vista operating
system DVD to reboot the computer and repair the operating system. Make sure that your most
recent backup (stored on discs or on an external drive) is easily accessible. To order a Windows Vista
operating system DVD, go to
http://www.hp.com/support, select your country or region, and follow the
on-screen instructions. You can also order the DVD by calling technical support. For contact
information, refer to the Worldwide Telephone Numbers booklet included with the computer.
CAUTION: Using a Windows Vista operating system DVD completely erases hard drive contents
and reformats the hard drive. All files you have created and any software installed on the computer
are permanently removed. When reformatting is complete, the recovery process helps you restore the
operating system, as well as drivers, software, and utilities.
To initiate recovery using a Windows Vista operating system DVD, follow these steps:
NOTE: This process takes several minutes.
1. If possible, back up all personal files.
2. Restart the computer, and then insert the Windows Vista operating system DVD into the optical
drive before the Windows operating system loads.
3. When prompted, press any keyboard key.
4. Follow the on-screen instructions.
5. Click Next.
