asked Apr 7, 2017 in PC Performance & Maintenance by Ryan

I am using an Hp pavilion laptop and it has been found that when Windows starts loading it displays a black screen with any of the following error messages - “UNMOUNTABLE_BOOT_VOLUME”

“windows\system32\config\system” or “hal.dll is missing or corrupted”. Kindly help me in fixing these problems. Thanks in advance.

Your system is displaying this type of error message because sometimes some system files get damaged or misplaced from their exact location. In order to get rid of this issue, you need to run SFC command, this command is also known as system file checker. After running this command all your corrupted and damaged system files  get repaired automatically. To do so, follow the steps:


Step 1: Open the command prompt on your system with admin privilege.
Step 2: Type sfc/scannow and hit enter key, this command will take some more time to complete.
