Backup and Recovery
Recovering system information
Recovery after a system failure is as complete as your most current backup. HP recommends that you create 
recovery discs immediately after software setup. As you add new software and data files, you should continue to 
back up your system on a regular basis to maintain a reasonably current backup.
Tools provided by the operating system and Recovery Manager software are designed to help you with the 
following tasks for safeguarding your information and restoring it in case of a system failure:
■Creating a set of recovery discs (Recovery Manager software feature). Recovery discs are used to start up 
(boot) your computer and restore the operating system and software programs to factory settings in case of 
system failure or instability.
■Backing up your information regularly to protect your important system files.
■Creating system restore points (operating system feature). System restore points allow you to reverse 
undesirable changes to your computer by restoring the computer to an earlier state.
■Recovering a program or driver (Recovery Manager software feature). This feature helps you reinstall a 
program or driver without performing a full system recovery.
■Performing a full system recovery (Recovery Manager software feature). With Recovery Manager, you can 
recover your full factory image if you experience system failure or instability. Recovery Manager works from 
a dedicated recovery partition (select models only) on the hard drive or from recovery discs you create.
✎Computers with a solid-state drive (SSD) may not have a recovery partition. Recovery discs have been included 
for computers that do not have a partition. Use these discs to recover your operating system and software. To 
check for the presence of a recovery partition, select Start, right-click Computer, click Manage, and then click 
Disk Management. If the partition is present, an HP Recovery drive is listed in the window.
Creating recovery discs
HP recommends that you create recovery discs to be sure that you can restore your system to its original factory 
state if you experience serious system failure or instability. Create these discs after setting up the computer for the 
first time.
Handle these discs carefully and keep them in a safe place. The software allows the creation of only one set of 
recovery discs.
Note the following guidelines before creating recovery discs:
■You will need high-quality DVD-R, DVD+R, BD-R (writable Blu-ray), or CD-R discs. All these discs are 
purchased separately. DVDs and BDs have a much higher capacity than CDs. If you use CDs, up to 20 discs 
may be required, whereas only a few DVDs or BDs are required.
✎Read-write discs, such as CD-RW, DVD±RW, double-layer discs, 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 can be created per computer. 
■Number each disc before inserting it into the optical drive. 
						

							8–2Maintenance and Service Guide
Backup and Recovery
■If necessary, you can exit the program before you have finished creating the recovery discs. The next time you 
open Recovery Manager, you will be prompted to continue the disc creation process.
To create a set of recovery discs: 
1. Select Start > All Programs > Recovery Manager > Recovery Disc Creation.
2. Follow the on-screen instructions.
Backing up your information
As you add new software and data files, you should back up your system on a regular basis to maintain a 
reasonably current backup. Back up your system at the following times:
■At regularly scheduled times
✎Set reminders to back up your information periodically.
■
Before the computer is repaired or restored
■Before you add or modify hardware or software
Note the following when backing up: 
■Create system restore points using the Windows® System Restore feature, and periodically copy them to disc.
■Store personal files in the Documents library and back up this folder periodically.
■Back up templates stored in their associated programs.
■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 reset your preferences. 
To copy the screen and paste it into a word-processing document, follow these steps:
a. Display the screen. 
b. Copy the screen:
To copy only the active window, press alt+fn+prt sc.
To copy the entire screen, press fn+prt sc.
c. Open a word-processing document, and then select Edit > Paste.
d. Save the document.
■You can back up your information to an optional external hard drive, a network drive, or discs.
■When backing up to discs, use any of the following types of discs (purchased separately): CD-R, CD-RW, 
DVD+R, DVD-R, or DVD
±RW. The discs you use will depend on the type of optical drive installed in your 
computer.
✎DVDs store more information than CDs, so using them for backup reduces the number of recovery discs 
required.
■
When backing up to discs, number each disc before inserting it into the optical drive of the computer.
Using Windows Backup and Restore
To create a backup using Windows Backup and Restore, follow these steps:
✎Be sure that the computer is connected to AC power before you start the backup process. 
						

							Backup and Recovery
Maintenance and Service Guide8–3
✎The backup process may take over an hour, depending on the file size and the speed of the computer.
1. Select Start > All Programs > Maintenance > Backup and Restore.
2. Follow the on-screen instructions to set up and create a backup.
✎Windows® includes the User Account Control feature to improve the security of your 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 system restore points
When you back up your system, you are creating a system restore point. 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 made to your system.
✎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 system files and settings.
When to create restore points
■Before you add or extensively modify software or hardware
■Periodically, whenever the system is performing optimally
✎If you revert to a restore point and then change your mind, you can reverse the restoration.
Create a system restore point
1. Click Start > Control Panel > System and Security > System.
2. In the left pane, click System Protection.
3. Click the System Protection tab.
4. Under Protection Settings, select the disk for which you want to create a restore point.
5. Click Create.
6. Follow the on-screen instructions.
Restore to a previous date and time
To revert to a restore point (created at a previous date and time), when the computer was functioning optimally, 
follow these steps:
1. Click Start > Control Panel > System and Security > System.
2. In the left pane, click System protection.
3. Click the System Protection tab.
4. Click System Restore.
5. Follow the on-screen instructions.

Backup and Recovery
Per fo rm in g  a rec over y
✎You can recover only files that you have previously backed up. HP recommends that you use HP Recovery 
Manager to create a set of recovery discs (an entire drive backup) as soon as you set up your computer.
Recovery Manager software allows you to repair or restore the system if you experience system failure or 
instability. Recovery Manager works from recovery discs or from a dedicated recovery partition (select models 
only) on the hard drive. However, if your computer includes a solid-state drive (SSD), you may not have a recovery 
partition. If that is the case, recovery discs have been included with your computer. Use these discs to recover your 
operating system and software.
✎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 recovers 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.
Recovering from the recovery discs
To restore the system from the recovery discs:
1. Back up all personal files.
2. Insert the first recovery disc into the optical drive and restart the computer.
3. Follow the on-screen instructions.
Recovering from the dedicated recovery partition (select models only) 
✎Computers with an SSD may not have a recovery partition. If the computer does not have a recovery partition, 
you will not be able to recover using this procedure. Recovery discs have been included for computers that do 
not have a partition. Use these discs to recover your operating system and software.
On some models, you can perform a recovery from the partition on the hard drive, accessed by pressing either the 
Start button or
f11. This restores the computer to its factory condition.
To restore the system from the 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 on the bottom of the screen. Then, Press f11 while the ”Press  for recovery” 
message is displayed on the screen.
✎2. Click System Recovery in the Recovery Manager window.
3. Follow the on-screen instructions.
