BobA

My system crashed. When I tryed to reboot I get "Windows
could not start because the following file is missing or
corrupt:<windows root>\system32\ntoskrn.exe Please re-
install a copy of the above file"

I have tryed to use the XP installation CD and I can get
to the repair postion but I can't understand how to
restore this file. Can anyone help?

thanks Bob

What you booted to with the CD is the Recovery Console.
Assuming you have an actual XP CD as opposed to a recovery CD, try a Repair
install as follows:

NOTE, while a repair install should leave your data files intact, if
something goes wrong during the repair install, you may be forced to start
over and do a clean install of XP. If you don't have your data backed up,
you would lose your data should that eventuality occur.

Boot from the CD. If your system is set to be able to boot from the CD, it
should detect the disk and give a brief message, during the boot up, if you
wish to boot from the CD press any key.

Once you have pressed a key, setup should begin. You will see a reference
asking if you need to load special drivers and another notice that if you
wish to begin the ASR (Automatic Recovery Console) depress F2. Just let
setup run past all of that. It will continue to load files and drivers.

Then it will bring you to a screen. Eventually, you will come to a screen
with the option to (1) setup Windows or (2) Repair Windows Installation
using the Recovery console.

***NOTE*** The first option, to setup Windows is the one you want and
requires you to press enter. When asked, press F8 to accept the end user
agreement. Setup
will then search for previous versions of Windows. Upon finding your
version, it will ask if you wish to Repair your current installation or
install fresh. Press R, that will run a repair installation. From there
on, follow the screens.

If you only have a recovery CD, your options are quite limited. You can
either purchase a retail version of XP will allow you to perform the above
among other tools and options it has or you can run your system recovery
routine with the Recovery CD which will likely wipe your drive, deleting all
files but will restore your setup to factory fresh condition.

sorry, my English is not very well

I had the same screen. I tried three computers and all three gave the same screen. My keyboard won't work either. It wasn't nessesery to reinstall ntoskrn.exe cause there was a broken mouse (short-circuiting). I had to change the mouse and all the problems were over.
good luck
