HP Pavilion Notebook Recovery Manager

Someone had a problem with HP Laptop particularly the system reported "hard disk does not exist" message during the boot up process. At first I thought that the hard disk is gone. This is too bad and I wished this is not true. So, I tried with the F11 key just after turning on the laptop. Luckily the recovery menu appears, which indirectly rejects the "hard disk does not exist" message. Nevertheless, the message remains an unsolved mystery to me.

Ada seseorang mengalami masalah dengan Laptop HP di mana sistem melaporkan mesej "hard disk does not exist" semasa proses boot up (ketika komputer dihidupkan). Pada mulanya saya menyangka hard disk sudah rosak. Ini adalah teruk dan saya harap ia tidak benar. Maka saya cuba dengan menekan kekunci F11 tatkala menghidupkan laptop. Mujurlah menu recovery muncul yang sekaligus menafikan mesej "hard disk does not exist". Begitupun, mesej tersebut kekal sebagai satu misteri yang belum terungkai kepada saya.

     Click "Next" after the backup to proceed. Click "Next" again to begin the recovery process. You don't need to do anything; just watch. The process takes between 20 and 45 minutes, depending upon your system. During the recovery, the computer reboots several times. Don't tap "F11" any more, just let it work. When the computer boots to the Windows desktop and doesn't open any new programs or installation wizards, the recovery is complete. Your system is back to its factory configuration.
