I'm a new diskeeper user and had defragmented my drives (C:\ and D:\) for the first time yesterday . Thereafter I restarted my computer as it asked me to do after installing Windows Update . Now, when it powers on during restart it does not start at all . Instead it gives a warning that the 'ntoskrnl.exe' file is either corrupt or missing and advices me to install another copy of the file . Now that I have the file with me I need it to start atleast once so I can copy it in the system32 folder . Please help me . cry2


PS: I have already tried out all the options on 'F8' during startup , but to no avail .

Try this

1. Start the computer by using your Windows XP CD-ROM. Press any key to boot from the CD.
2. After the setup files are finished loading press R to repair using Recovery Console.
3. When you are in the recovery console, select the installation to log on to (usually number 1), and then press ENTER.
4. Login to the Administrator account by typing the password for this account, and then press ENTER.
5. At the recovery console command prompt, type the following command, and then press ENTER:

For Uni-Processor systems:
expand cd-rom:\i386\ntoskrnl.ex_ drive:\Windows\system32
For Multi-Processor systems:
expand cd-rom:\i386\ntkrnlmp.ex_ drive:\Windows\system32\ntoskrnl.exe

Cd-rom is the drive letter of your CD-ROM drive, and drive is the drive letter of the hard disk on which windows is installed.
6. If you receive a prompt to overwrite the file, press Y.
7. Type exit, and press ENTER at the command prompt.

I am thankful to you for replying to this problem . Your the first and the only one to do so . I am a Sony Vaio TX37GP user . This notebook does not come with any recovery disk or the windows installation disc . As a result of which I am only able to burn a bootable disk of i386 folder from another computer and boot from it then a Caldera DR-DOS 7.03 pops up . I do not know what to do . My pc  is now off for quite a lot of time now due to this outcome . 
Please guide me likewise . Thanks . please

Do you have access to another computer?

You could try copying the 'ntoskrnl.exe' file from one to the other.

Go to C:\Windows\System32 and rename the existing file to something like ntoskrn.old.exe

Then copy the file from the pen drive directly into C:\Windows\System32

If you are doing this via a command prompt, you won't be able to access the pen drive as it's USB. Copy it onto a CD first then you can use the commands:

REN<space> C:\Windows\System32\ntoskrn.exe<space> ntoskrn.old.exe

Copy 'D':\ntoskrn.exe <space>C:\Windows\System32\

Note that the 'D' should be the letter assigned to your CD drive.

Does your CD/DVD drive work now?

If it does, it should be easy to find out what drive letter it is.

D is the norm.

Appreciated  .

Well done!

(Looks like it was all down to a corrupted registry.)
