							7 Backup and recovery
Your computer includes tools provided by the operating system and HP to help you safeguard your
information and restore it if ever needed. This chapter provides information on the following topics:
●Creating a set of recovery discs or a recovery flash drive (Recovery Manager software feature)
●Performing a system restore (from the partition, recovery discs, or a recovery flash drive)
●Backing up your information
●Recovering a program or driver
Restore
In the event of hard drive failure, to restore your system to its factory image you will need a set of
recovery discs or a recovery flash drive that you can create using HP Recovery Manager. HP
recommends that you use this software to create either a set of recovery discs or a recovery flash
drive immediately after software setup.
If for some other reason you need to restore your system, this can be achieved using the HP
Recovery partition (select models only), without the need for recovery discs or a recovery flash drive.
To check for the presence of a recovery partition, click Start, right-click Computer, click Manage,
and then click Disk Management. If the recovery partition is present, a Recovery drive is listed in
the window.
CAUTION:HP Recovery Manager (partition, or discs/flash drive) restores only software that was
preinstalled at the factory. Software not provided with this computer must be reinstalled manually.
NOTE:Recovery discs have been included if your computer does not have a recovery partition.
106 Chapter 7   Backup and recovery 
						

							Creating restore media
HP recommends that you create either a set of recovery discs or a recovery flash drive to be sure that
you can restore your computer to its original factory state if the hard drive fails, or if for any reason
you cannot restore using the recovery partition tools. Create these discs or the flash drive after setting
up the computer for the first time.
NOTE:HP Recovery Manager allows the creation of only one set of recovery discs or one recovery
flash drive. Handle these discs or flash drive carefully and keep them in a safe place.
NOTE:If your computer does not include an integrated optical drive, you can use an optional
external optical drive (purchased separately) to create recovery discs, or you can purchase recovery
discs for your computer from the HP Web site. If you use an external optical drive, it must be
connected directly to a USB port on the computer, not to a USB port on an external device, such as a
USB hub.
Guidelines:
●Purchase high-quality DVD-R, DVD+R, DVD-R DL, or DVD+R DL discs.
NOTE:Read-write discs, such as CD-RW, DVD±RW, double-layer DVD±RW, and BD-RE
(rewritable Blu-ray) discs, are not compatible with the Recovery Manager software.
●The computer must be connected to AC power during this process.
●Only one set of recovery discs or one recovery flash drive can be created per computer.
NOTE:If you are creating recovery discs, number each disc before inserting into the optical
drive.
●If necessary, you can exit the program before you have finished creating the recovery discs or
recovery flash drive. The next time you open Recovery Manager, you will be prompted to
continue the backup creation process.
To create a set of recovery discs or a recovery flash drive:
1.Select Start > All Programs > Recovery Manager > Recovery Media Creation.
2.Follow the on-screen instructions.
Creating restore media 107 
						

							Performing a system restore
Recovery Manager software allows you to repair or restore the computer to its original factory state.
Recovery Manager works from recovery discs, a recovery flash drive, or from a dedicated recovery
partition (select models only) on the hard drive.
NOTE:A system restore needs to be performed if the computer hard drive has failed or if all
attempts to correct any functional computer issues fail.
A system restore should be used as a final attempt to correct computer issues. Note the following
when performing a system restore:
●You can restore only the system that you have previously backed up. HP recommends that you
use HP Recovery Manager to create either a set of recovery discs or a recovery flash drive as
soon as you set up the computer.
●Windows has its own built-in repair features, such as System Restore. If you have not already
tried these features, try them before using Recovery Manager.
●Recovery Manager restores only software that was preinstalled at the factory. Software not
provided with this computer must be downloaded from the manufacturers Web site or reinstalled
from the disc provided by the manufacturer.
Restoring using the dedicated recovery partition (select models only)
When using the dedicated recovery partition, there is an option to back up pictures, music and other
audio, videos and movies, recorded TV shows, documents, spreadsheets and presentations, e-mails,
Internet favorites and settings during this process.
To restore the computer from the recovery partition, follow these steps:
1.Access Recovery Manager in either of the following ways:
●Select Start > All Programs > Recovery Manager > Recovery Manager.
– or –
●Turn on or restart the computer, and then press esc while the “Press the ESC key for
Startup Menu” message is displayed at the bottom of the screen. Then, press f11 while
the “F11 (System Recovery)” message is displayed on the screen.
2.Click System Recovery in the Recovery Manager window.
3.Follow the on-screen instructions.

Performing a system restore 109 
						

							Backing up and recovering your information
It is very important to back up your files and keep any new software in a safe place. As you add new
software and data files, continue to create backups on a regular basis.
How completely you are able to recover your system depends on how recent your backup is.
NOTE:A recovery from your most recent backup needs to be performed if the computer has a virus
attack or if any major system components fail. In order to correct computer issues, a recovery should
first be attempted before a system restore is attempted. You can back up your information to an
optional external hard drive, a network drive, or discs.
Back up your system at the following times:
●At regularly scheduled times
TIP:Set reminders to back up your information periodically.
●Before the computer is repaired or restored
●Before you add or modify hardware or software
Guidelines:
●Create system restore points using the Windows System Restore feature, and periodically copy
them to an optical disc or an external hard drive. For more information on using system restore
points, refer to Using Windows system restore points.
●Store personal files in the Documents library and back up this folder periodically.
●Save customized settings in a window, toolbar, or menu bar by taking a screen shot of your
settings. The screen shot can be a time-saver if you have to re-enter your preferences.
To create a screen shot:
1.Display the screen you want to save.
2.Copy the screen image:
To copy only the active window, press alt+fn+prt sc.
To copy the entire screen, press fn+prt sc.
3.Open a word-processing document, and then select Edit > Paste. The screen image is added to
the document.
4.Save and print the document.

							Using Windows Backup and Restore
Guidelines:
●Be sure that the computer is connected to AC power before you start the backup process.
●Allow enough time to complete the backup process. Depending on file sizes, it may take over an
hour.
To create a backup:
1.Select Start > Control Panel > System and Security > Backup and Restore.
2.Follow the on-screen instructions to schedule and create a backup.
NOTE:Windows includes the User Account Control feature to improve the security of the computer.
You may be prompted for your permission or password for tasks such as installing software, running
utilities, or changing Windows settings. Refer to Help and Support for more information.
Using Windows system restore points
A system restore point allows you to save and name a snapshot of your hard drive at a specific point
in time. You can then recover back to that point if you want to reverse subsequent changes.
NOTE:Recovering to an earlier restore point does not affect data files saved or e-mails created
since the last restore point.
You also can create additional restore points to provide increased protection for your files and
settings.
When to create restore points
●Before you add or modify software or hardware
●Periodically, whenever the computer is functioning optimally
NOTE:If you revert to a restore point and then change your mind, you can reverse the restoration.
