ntoskrnl.exe missing


Overclocked Like A Mother
Hi Guys,

I am getting this error on an XPPro machine:

<windows root>\system32\ntoskrnl.exe

Please reinstall a copy of the above file.

I would like to know how to reinstall this file. I searched and read that I have to use Recovery Console. Would someone be able to guide me on this issue?

Thanks in advance.

It should be in the dllcache so boot to the RC and issue this command

copy c:\windows\system32\dllcache\ntoskrnl.exe c:\windows\system32\

Great, Thanks J and Nets.

Will try that right away. Copied that post onto a .doc for future as well.



Usually there isn't a copy of Ntoskrnl.exe in the dllcache folder.

There is one inside the \Windows\Driver Cache\i386 folder.
If you have installed one of those Windows updates that replace the kernel, it is directly in this folder.
The command at the recovery console would be
copy "C:\Windows\Driver Cache\i386\ntoskrnl.exe" C:\Windows\system32

If you haven't applied one of these updates but have Service Pack 1 installed the ntoskrnl.exe is inside the sp1.cab file.
The command in this case
expand "C:\Windows\Driver Cache\i386\sp1.cab" /f:ntoskrnl.exe C:\Windows\system32

In case you don't even have SP1 installed, replace sp1.cab in the command by driver.cab.

That's a good question, Xie.....

As for the machine itself, I won't be able to try it until tonight when I head over to this guy's place. Will keep posted.

I think I will try that sfc/scannow command as well.

Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
