Overview of Recovering the OS or Reinstalling the Operating System
This document pertains to HP and Compaq notebook computers.
Performing a system recovery to return the computer to its original condition may be necessary if the operating system is damaged, the hard drive is corrupted, or the computer is infected by a virus. Performing a system recovery removes all software and files saved to the hard drive, reinstalls the original operating system, and then configures the settings for the default programs. This document provides an overview of information available to help you perform a system recovery.
If you have never run a system recovery and you want to review a list of frequently asked questions, see FAQ on Repairing or Reinstalling the Operating System for more information.
Preparing for a system recovery
Before performing a system recovery, you can complete several processes that may prevent the need to run a system recovery or help make sure your system recovery is successful. Review the topics below and click on the links for detailed information and step-by-step instructions for each topic.
Back up important files
HP recommends that you make backup copies of your files on a regular basis, and that you store the backed-up files on a CD/DVD or other external media in a separate physical location, away from the computer. Doing scheduled backups will help you to recover some, if not all, of your information in the event that something happens to the original files on your computer.
When deciding which files you want to save, make a list of important information that you cannot easily replace. The list will also give you a reference list in the event that you need to retrieve the files. For more information on backing up your important files, see Backing Up Your Files (Windows 8) , Backing Up Your Files (Windows 7) , or How to Back Up User Files (Windows Vista or XP) .
Performing a system recovery will destroy all the files on the hard drive . In the event you did not back up your files prior to running a system recovery, the Recovery Manager displays a prompt to make a backup copy of your files before it performs any action that might erase or delete any files.
Correct startup or boot issues
If your computer does not start or boot into Windows, it may be possible to correct the issue without performing a system recovery. Performing a system recovery is a destructive process that erases all the files and programs on your computer. Recovering an operating system will take an hour or more to complete. You must also configure the pre-installed hardware and software components, and reinstall all your programs and personal files. The entire process may take several hours. Finding and correcting startup or boot issues before performing a system recovery may save time.
Many startup or boot issues are caused by minor problems that are easily corrected. Before performing a system recovery, try to determine if other, non-destructive, corrective actions will fix the problem. Refer to Overview of How to Troubleshoot Problems When a Computer Does Not Start Up or Boot Properly for a list of startup or boot symptoms with troubleshooting steps.
Complete a Windows System Restore
If your computer suddenly develops a problem, perform a Windows System Restore to try to resolve the issue before performing a system recovery with the HP Recovery Manager. Windows System Restore is a Microsoft program and should not be confused with HP Recovery Manager. The Microsoft Windows System Restore function returns the computer to a previously chosen restore point, which resets all of the settings for the operating system to those settings that existed at the time that the restore point was created. No personal data files, such as email, documents, or pictures are lost. For more information on Windows System Restore, see Using Microsoft System Restore (Windows 8) , Using Microsoft System Restore (Windows 7) , Using Microsoft System Restore (Windows Vista) , or Using Microsoft System Restore in Windows Me and XP .
Find recovery discs
One option for performing a system recovery is to use system recovery discs. Prior to 2006, HP provided operating system CD discs or recovery discs for most computers. After 2006, HP configured computers with a Recovery Manager function that lets you recover the system from files stored on a partition on the hard drive. Recovery Manager also lets you create a set of recovery discs that contain the files that are specific to your computer. For most models, replacement recovery discs can be purchased from HP. See the HP support document HP PCs - Looking for Recovery Discs? for more information.

Solve common system recovery errors
Performing a system recovery can be a complicated task. The single most common cause of recovery errors is the interruption of the process or turning off of the computer before the recovery and setup is complete. For additional recovery issues see System Recovery May Fail or Display Error Message (Windows 7, or Vista) .
Completing a system recovery
After performing a system recovery, you must reinstall and update all of your software and drivers, and reestablish the Internet connection. Use the original manufacturer's disc to install your software programs, and then go to the manufacturer's web sites to download and install all updates.
