  1. You can just insert the win8 disc and let the repair starts.

    ok. is there a possibility of the .sys file being corrupt ? Even though the repair happens the installation fails to load the operating system and the error message appears
  3. you have to re install the windows

    I would recommend using the System File Checker utility (SFC) to check your core operating system files for corruption and to repair them. In order to use SFC, you will need access to a Windows Recovery Environment (Win RE) through which you can access the Command Prompt. If you have installation media that will work, just select Repair your computer to access WinRE and locate the Command Prompt under Troubleshooting and Advanced Options. Once this is open you can enter the following command

    sfc /scannow

    If you receive a message Windows resource protection could not perform the requested operation, you can instruct the operation to be performed offline using the following command

    sfc /scannow /offbootdir=C:\ /offwindir=D:\windows

    where D is the drive letter assigned to the Windows partition. To locate which drive letter is assigned to your Windows partition you can enter

    list volume

    If the volume is not labeled, it is most likely the largest volume on the disk unless you have a second storage disk or have altered the partitions from their default.
