I turned on my computer this morning and it would not boot up.  The only message I have is this:

 

Windows could not start because the following file is missing or corrupt:

\WINDOWS\SYSTEM32\CONFIG\SYSTEM

 

You can attempt to repair this file by starting windows setup using the original Setup CD-ROM.

Select 'r' at the first screen to start repair.

 

 

 

I can get into the BIOS but cannot start in safe mode.

 

Any help appreciated.
