Hi,
Unless he is an expert assume he used a proggy to do it. Check in your
"Program Files" directory for anything that sounds like a bootup
screen changer and run it, chances are it has a restore function.
Sometimes the obvious is overlooked.

And if all else fails;
Missing or corrupt ntoskrnl.exe file
If the ntoskrnl.exe file is corrupt or missing this can also generate the
error. To restore this file follow the below steps.
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.. Type expand d:\i386\ntoskrnl.ex_ c:\windows\system32
6.. You will then be prompted if you wish to overwrite the file type Y
and press enter to overwrite the file.
7.. Type exit to reboot the computer.
