How to Manually Start an HP Desktop Recovery Partitionby Jason Gordon
The HP Recovery Partition that comes pre-installed on most new HPs is like built-in insurance if your system becomes unstable or fails. If the problem is severe enough, you may not be able to start the HP Desktop Recovery Manager from Windows but you can start it manually by following the steps below.
Disconnect all peripheral devices and power on the computer.
Press the F11 key after the computer first powers on to start the HP Recovery Manager.
Follow the on-screen instructions to back up recoverable files on the hard drive to an external drive or media.
Continue following the instructions to recover the hard drive to its original factory condition.
Click "Finish" when the recovery is complete. Reconnect devices and reboot the computer. Reinstall software and update Windows and HP to current settings.
