I got the following error while loading SP1 on XP. Windows could not start because the follwoing file is missing or corrupt: <windows root>\system32\ntoskrnl.exe. Please re-install a copy of the above file. Problem I have is I cant get past this message. Wont let me start in safe mode, previously saved installs, etc.... I have another computer exactly like the affected computer so I planned on copying ntoskrnl.exe from the good one to the bad one but I cant get past the error message.... any suggestions...
