Windows not booting
Having major problems on another PC.
On startup, the system goes straight to the following error message:
-------
Windows could not start because the following file is missing or corrupt:
<Windows root>\system32\ntoskrnl.exe.
Please re-install the above file.
-------
However, there appears to be no way of re-installing it, if you hit enter the system just reboots. It is going straight to this error message and is not giving the options for safe mode etc.
I have tried to reinstall windows but it says it can't do it without formatting, and there is data on the PC that needs to be retrieved. I can get into the repair console but don't have a clue what do do once in there?
Advice please? Many thanks in advance.
