I have a computer that is running Windows XP. For some reason, the other day it wouldn't start giving me the following message:

"ntoskrnl.exe is missing or corrupt"

So I put the XP disc in the tray and fired up the repair console and ran the following:

chkdsk /r

It was on for about eight hours and it got to about 52% I believe. Then there was a power outage and the computer shut down (obviously). Today when I was booting it, it isn't even detecting there's an OS anymore. If I boot the computer with no cd in the tray it says:

"Reboot and select a proper Boot device or Insert Boot Media in selected Boot device and press a key"

If I run the repair console, or the xp installation program it isn't finding any OS installations.

Any ideas on what to do next? Any help is appreciated. Thanks!

Update: After turning boot-time diagnostics on, I got this message when booting without cd (instead of the previous one):

"Couldn't open drive multi(0)disk(0)rdisk(0)partition(2)"
