Sometime ago I remember refreshing WinXP by using the original instal disk ... sometimes called a non-destructive re-install.
I now have need to do the same again (missing files errors on boot-up), but cannot remember the steps after getting as far as the screen that lets me choose disk and partions etc.
Again from memory there used to be an offer of selecting the O/S and then R for repair, but I cannot find that option anywhere.
Any clues please?
ALSO, can one run the SFC (System File Checker) on an external disk that holds an O/S?
R.
