Wont boot

[Mr.Nasty]

I made a huge mistake....I changed my boot screen...and now it wont boot, not even in safe made or last known good config. I change boot screens before but i never had this problem. I am running windows XP and its a notebook. I didnt change anything and i know its the nostkl (whatever it is) file because that is the only thing i changed before i started changed stuff. I did make a bakc up of the file so how do i put it back to normal? i dont feel like losing all the junk on my notebook, but i gues thats the price i have to pay... and suggestions before i go and completely redo my notebook? Thanks

You will need to boot from the XP cd, and go into the Recovery Console.

From there, using standard DOS commands, you can copy your backup over the bad ntoskrnl.exe

If you do not know the commands, I'll tell you exactly how to do it.
