Windows 8 ntoskrnl.exe is corrupt

Hi Guys

One of my clients called today, her Windows 8 machine keeps booting in to repair mode. I talked her through on how to look at the repair log (c:\Windows\System32\LogFiles\Srt\SrtTrail.txt). The message was "C:\Windows\System32\ntoskrnl.exe" is corrupt.

I'm wondering if anyone knows how I can tackle this problem? I don't think she has Windows 8 OS media, however I have one for my machine.

Thanks in advance.

As per MS on Windows 8 NTOSKERNEL:

Method 1: Run a system file checker scan and check if that helps.

Refer the following steps to run SFC scan:

a) Move the mouse pointer to bottom left of the screen where you see preview of start menu and Right-click to bring up a list of Windows settings.
b) Click on ‘Command Prompt (Admin) to bring up elevated command prompt. Note: Click ‘Yes’ if it prompts for permission.
c) In the command prompt type in the following command: ‘sfc /scannow’.

Note: It may ask for windows installation DVD to fix and to enable SFC to make more than minor repairs. Some files saved on your computer might get deleted when fixing corrupted files.

Method 2: Let us check if there are any errors on the Hard disk.

Please refer to the section "To repair a drive to perform check disk".

Important Note: While performing chkdsk on the hard drive if any bad sectors are found on the hard drive when chkdsk tries to repair that sector if any data available on that might be lost.

Hope the information helps to fix the blue screen issue. If the issue persists, or for any Windows related queries, feel free to post. We will be glad to assist you.
