after pressing start button at windows xp it shows all program except RUN option. It does not allow to open window for command prompt through all programs-> accessories-> command prompt. It does not allow to open window in safe mode. If I try to remove any program through control panel. It instantly closed itself. How i can repair my window?
Boot from Windows CD and select 'r' to repair the OS. Make sure CD ROM is 1st boot device in F2 (Setup), first.
