My PC won't boot and tells me that I have a corrupt or missing ntoskrnl.exe file. I followed the directions to fix the file by expanding the file from the Windows CD to the system32 directory and it tells me "access denied". The solution had said to boot to the CD, then go to windows recovery, login as administrator and expand the file. When I went to windows recovery it never asked me to logon as administrator nor did it ask for a password.
 
I'm stuck, what do I do next?
 
thanks
