How do I install old DOS and Windows 3.1 on a Win95 system?
I do not recommend installing old DOS on a Win95 machine at all. Win95’s included MS-DOS 7.0, in Single Mode, can run anything that previous versions of DOS can, including Windows 3.1 or Windows for Workgroups! If you have to run old DOS programs that don’t run in DOS sessions in Win95, check out the Running MS-DOS Games page. With that aside, to install the missing utilities that DOS 7.0 blatantly forgot from DOS 6.
