Although you don't have the option to uninstall if you install Microsoft MS- DOS 6 or later Upgrade using the /G and /H switches together, Setup still creates an OLD_DOS.x directory. Because you cannot uninstall, it is safe to delete the OLD_DOS.x directory using DELOLDOS.EXE.


Setup /G disables the Uninstall feature of MS-DOS. Setup /H installs MS-DOS with very few prompts for user input and cannot be used without the /G switch.

Setup uses the OLD_DOS.x directory to create temporary CONFIG.SYS and AUTOEXEC.BAT files when it modifies them. Setup does not copy any other MS-DOS files to this directory when you install MS-DOS 6 or later Upgrade using the /G and /H switches together.
