The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

Ntoskrnl.exe file is missing or corrupt .....

Zone: Operating Systems Miscellaneous

Tags: missing

Hi Team,

I hope you can help me with this, I had this problem awhile back but I corrected it by simply formatting the drive which is just not feasable this time.

History: I was ripping a DVD using SmartRipper when I started to think why the DVD Speed is so slow. 1x 2x max. the DVD drive is 16X max. SO i read up a little and it looked like I was not using the ASPI drivers which would dramitally increase the performance of the ripper and drive.

So i installed ASPI checker from http://www.doom9.org/Soft21/SupportUtils/aspichk.rar

ASPI checker tells that the drivers were not installed properly so I installed Force ASPI fromhttp://www.doom9.org/Soft21/SupportUtils/forceaspi17.rar.

Ok, After the install of ForceASPI i rebooted .. No error on reboot. So i checked the ASPI install with ASPI Checker but still the same message about the drivers not installed properly.

So, I ran ForceASPI again but this time ran a .bat file that automatically dumps the previous ASPI .sys .ini files and 1 .exe file called wowpow.exe (i think). Anyways i ran the install.bat again and rebooted when prompted and was then shortly thereafter met with the pending black box of doom . And the message read as follows

Windows could not start because the following file is missing or corrupt.

<windows root>\system32\ntoskrnl.exe

Please reinstall a copy of the above file.

What im looking for is a step by step follow through of how to extract a good copy of this file back into the system32 directory. I do support myself but for handheld devices. Im a little weary of the DOS command.

Your help would be greatly appreciated, I have no idea what to rate this question as this is my first post.

Thanks

you MUST check your computer for a virus. This sounds like symptoms of a virus infection.

dhickey:

Hi LeafsFan and Dimitri.

I appreciate both of your answers and I plan on applying both when I reach home tonight. I apologize I should have mentioned that I am using WinXP, however I should be able to modify the boot.ini file in the same manner. Does anyone know of a virus utility i can run in DOS. I will let you know how it turns out.

Thanks

I think you trashed some files. Cross fingers.

Lucky for you Windoze is more self healing each version, especially for files like these. Boot the Install CD like you would install, but do not. Make menu selection of "repair" and get yourself to the Recovery Console. This can also (later) be added as menu option for booting ( a good idea IMO) but skip that for now.

The recovery should handle all the boot areas for you well enough, no matter what.

As fo DVD slowness, that a separate issue. Maybe a virus, maybe an anti-virus checking, looking over your shoulder each step. You may want to ensure it is only program running, using task manager and msconfig.

> I have no idea what to rate this question as this is my first post.

Sometimes we never know until it is solved....

Just be nice and don't just ask one point question, and fill up same thread with a new question each day.

Well as someone else said an up to date virus scanner is a must! I have had this problem more than once. If you have the windows cd boot into the recovery console and you will find ntoskrnl.ex_ in the I386 directory. This file needs to be expanded using the "expand" command ,, sorry im not exactly sure of the syntax at the moment but you can type expand /? to see how. As far as why this happened I personal had a virus called w32.pinfil or something like that. It spread to my other drives and was a pain to get rid of. I had to boot in safe mode and use norton. Although norton only quantined the file because it said access denied so I deleted them in the RC. The win32 virus likes to mess with exe extentions so it may have wondered around to ntoskrnl.exe. It did me 3 times untill I got a virus scanner.

O I also wanted to metion you can use windows sfc (system file checker) to check if your system files have been altered since your last install or service pack upgrade. BUT! keep in mind any applications you did not install using the <Add New Programs> button in <Control Panel/Add and Remove Programs> may have to be reinstalled. This is because many applications override system dll files so they can work. Much like win98 when it asked if u wanted to copy a file that was older then the existing. (Based on the time stamp I do beavle) So if u want to try it type sfc /scannow in run. OK im done now : o )

Ok im sorry to keep posting but I keep discovering new knowlege that may be helpfull to you guys. I am tring to Dual boot linux and windows 2000 but usiing the windows 2000s ntloader well i have to make a fat parition that both can read well i can`t mess with my 10gb (partiton magic won`t work for some reason) so i decided to change the jumpers to boot the 3gb (my other drive that was primary slave) first. I then copyed the required files from my 10gb to make it boot. It booted but when I selected an os i got the missing or corrupt ntoskrnl.exe error. So I remebered the boot.ini file tells the system were to find windows according to drives and were there located so i edited it. below is the old setup:
[boot loader]
timeout=10
default=multi(0)disk(0)rdisk(0)partition(2)\WINNT
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINNT="(D:) 2000 Datacenter Server" /fastdetect
multi(0)disk(0)rdisk(0)partition(1)\WINNT="(C:)2000 Datacenter server" /fastdetect

This is the new:
[boot loader]
timeout=10
default=multi(0)disk(0)rdisk(1)partition(2)\WINNT
[operating systems]
multi(0)disk(0)rdisk(1)partition(2)\WINNT="(D:) 2000 Datacenter Server(3gb hd as Master)" /fastdetect
multi(0)disk(0)rdisk(1)partition(1)\WINNT="(E:)2000 Datacenter server(3gb hd as Master)"

As you can see the value for rdisk is now 1 the first 3 () start counting from 0 and the last starts from 1. (schools good for something beavle it or not)

So to sum all that up you may have an incorrect boot.ini file thats pointing to no mans land causeing that error. Why it doesn`t just say that I will never know.

I've got the same error just today after udpating the dat files to my virus scan program. Gotten after the reboot to finish the installation. Can't get it to do the restore thing, Can't get it to boot to the installation cd. Can't get it to do much of anything except tell me I need to replace the file. Geezz. I need the dos commands to copy that file from the Windows XP Professional installation cd. I don't see any other way to fix this other than reformat and that's something I'd rather avoid.

Fear is your worst enemy. I have solved this on several machines, although when complete, the process is fuzzy (ususlly late at night). Start with a virus scan. Use a W98 boot disk and setup the scan on a CD. On my W2K Computer, I use McAfee. Go to program files/common Files/Network Assoc./Virusscan Engine/4.0xx and copy all the current files to the CD.
On XP, install the Recovery Console from the WXP CD. Read Q314477 and Q305595, 307654, 291980.

Go carefully, take notes! Next I used "Fixmbr" in recovery console. Try a restart here, if it fails, then continue. Then used "Bootcfg" as described in 291980.

I am fuzzy after this point. Good Luck

O sorry the Scan is run from a cmd prompt. "Scan /adl /clean /all"

See the Mcafee web site, look for "Scan from Dos"
