I have a corrupt or missing file as noted in the message "windows will not
start because the following file is missing or corrpupt
:\windows\system32\config\system

I have tried booting from the XP startup disc but at the Welcome to startup
blue screen when I press "R" for repair the computer just shuts down again.
I have tried tried safe mode; using last known configuration...etc but those
functions do not seem to work.

Any suggestions to get around this?
