My laptop appears to be a bit fucked

[Zodiac]

Now when starting up all I get is a blank screen with the following message:

Windows could not start because the following file is missing or corrupt:
<windows root>\system32\ntoskrnl.exe.
Please re-install a copy of the above file.

What the fuck does that mean? Have I killed it? I have googled the problem but frankly I don't have clue what any of the solutions are getting at... err, any tips?

1. Insert the Microsoft Windows XP CD. Note: If you have a recovery CD or a restore CD and not a Microsoft Windows XP CD it is likely the below steps will not resolve your issue.
2. Reboot the computer, as the computer is starting you should see a message to press any key to boot from the CD. When you see this message press any key.
3. In the Microsoft Windows XP setup menu press the R key to enter the recovery console.
4. Select the operating system you wish to fix, and then enter the administrator password.
5. Once at the recovery console type chkdsk /r
6. Once completed type exit and see if issue is resolved.
