Missing boot file:ntosknl.exe

Missing boot file:

I was reading about the missing ntoskrnl.exe file and I have the same

problem with my desktop computer.

This is the problem:

No safe mode is accessable or previous well last boot available. All say the

same about missing ntosknl.exe

I tried the R console and could not pass the "enter the administration

password" since the xp pro OS was installed by the previous owner I don't

have a clue of it. I pulled the HD and plugged it in as -slave in my other

comp. I can browse it and see all files, but I have little or no knowlegde

of how to replace or repare the missing file in question. Nor do I know if

it's possible to do through this method.

I wish I could retain those programs and files in that HD.

Any help in this matter will be greatly appreciated. thank you all.
