System Recovery
WARNING! This procedure will delete all user information. To prevent loss of information, be sure to back
up all user information so you can restore it after recovery.
System Recovery completely erases and reformats the hard disk drive, deleting all data files that you have
created, and then reinstalls the operating system, programs, and drivers. However, you must reinstall any
software that was not installed on the computer at the factory. This includes software that came on media
included in the computer accessory box, and any software programs you installed after purchase. Any
personal files must be restored from backups you made.
If you were not able to create system recovery DVDs or USB flash drive, you can order a recovery disc set
from support. Go to
http://www.hp.com/support, select your country or region, and follow the on-screen
instructions.
NOTE: Always use the System Restore procedure before you use the System Recovery program. See
System Restore on page 137.
You must choose one of the following methods to perform a System Recovery:
●
Recovery image — Run System Recovery from a recovery image stored on your hard disk drive. The
recovery image is a file that contains a copy of the original factory-shipped software. To perform a
System Recovery from a recovery image, see
System Recovery when Windows is responding
on page 138 or System Recovery when Windows is not responding on page 139.
●
Recovery media — Run System Recovery from recovery media that you have created from files stored
on your hard disk drive or purchased separately. See
System Recovery using recovery media (select
