ntoskrnl.exe missing or corrupt on boot

Hi....and....HELP!

My Win2000 Pro won't start up as I continue to get an error message stating that ..\system32\ntoskrnl.exe file is missing or corrupt. I try to boot and repair from the CD, but I still get this error. FYI: :-( I have no emergency boot disk).
I've checked, and the file is there. It's too large a file to copy from another system onto a disk in my A drive.

Any ideas how I can get past this?

Hi Mary,

This can be a scary one, for sure! Has anything changed about your system recently? Hardware/software installs? OS upgrade? Can you boot to safe mode? If so, you should have a look at your boot.ini file. Assuming that W2K is installed on the first partition of the (C: drive), on the only (or first)physical IDE harddisk, and firther assuming that this is the only OS you're running, boot.ini will say:

multi(0)disk(0)rdisk(0)partition(1)

In my experience, an error in boot.ini is the cause of the majority of these errors.

Just to clarify: when you attempt a "repair installation" from the CD, the same error appears before the process completes?

Feel free to email me if I can be of further assistance...my knowledge is limited, but I'd be glad to help.

Roger

Could be your ARC/path statment in the boot.in is no longer pinting to correct location for ntoskrnl.exe?

Quite why this would happen...?

Check out this M$ KB item:

http://support.microsoft.com/default.aspx?scid=KB;EN-US;Q153973&ID=KB;EN-US;Q153973

It contains another lnk which may be the one that will actually get you going again...?

W2K Repair 'tuts.'in case they are of help:

i.e. Q121517

BTW - you don't need an ERD; it's just a little eaasier... if you have one. Nontheless it would be good/wise to make one and keep it up-to-date when you do get back in?

Hi all,

I have the same problem with the Ntoskrnl.exe
I can't boot in safe mode or from cd-rom. How can I get in and edit the boot.ini file?
I need acces to this computer.

Please help.

Yeh, got the same problem. Installed W2K on a separate partition than that of XP. W2K loads up fine, but XP now has missing ntoskrnl. I installed W2K after XP - XP not quite there yet!!

I am running Win XP and I too have the same problem.

It causes my pc to sometimes not boot up, or if it does it doesn't allow me to type.
As i have a password on my admin account, I can't get in to remove/fix the file cause I can't type in my password.

I have fixed this twice now, the first time i removed my harddrive and put it in another machine and copied the file accross by booting off the other pcs HDD, this fixed the problem for about 3 hours then bang it happened again, so this time i formatted the HDD and reinstalled windows, but under FAT32 file system instead of NTFS. This solved the problem for about half a day and now i am stuck again, I am no longer getting the error message about ntoskrnl.exe but I know its possibly causing the problem, and i can't bloody type!
I thought the fresh install would fix it so silly me put a password on again, so can't get into fix it, and now my machine is really annoying cause it doesn't recognise the keyboard at all, ie: I can't even get into bios by pressing delete.

I re-installed Win2K over the top of the C:\winnt dir and selected the Repair option. Don't select the repair when you first boot up the installation disk. Select to install, then select your orginal c:\winnt dir. Next select to repair.

I had the same problem on my win xp machine. Phoned the manufacturer help line and was given the following instructions:

1. remove all wires from behind the CPU box ie power lead, printer, keyboard, mouse etc everything!

2. connect back only power lead, mouse, keyboard and VDU(screen).

3. boot up again.

It worked!!

I think the error is linked to the use of peripherals like printer etc.

I have a system is doing the same. This PC got hit by a virus though. The msg Low on Virtual Memory kept on poping up. I increased the virtual memory, reboot the sytem and bang, the NTOSKRNL.exe and HAL.DLL came up missing or corrupted. I tried to boot to dos prompt to replace the two files but W2K has no option to boot to command prompt, so I couldn't do that. I'm thinking about making that HDD as a secondary and run scandisk and replace the files that way.

My computer has been hit by a virus a couple of minths ago but i took care of that and switched to windows 2000 after formating the whhole drive I had windows 98 on my machine b4 formatting. The virtual memory problem and now the new thing ntoskrnl.exe are troublinggme so much.

Had the same problem yesterday with Win2k not booting because of a missing ntoskrnl.exe.

It appears to have been caused when I installed WinXP in my partition 3 - Win2k was already in p2.

I found and edited BOOT.INI (thanks Roger!) to point it back to p2. Now all's working OK again.
