Can I run the Windows 95 Setup program from MS-DOS? Do I lose any functionality?
If you have a running installation of Windows 3.x or Windows for Workgroups 3.x1, it is strongly recommended that you run Setup from your existing version of Windows. This provides the safest and smoothest installation. If you do run Setup from MS-DOS, and it detects Windows on the computer, it will recommend quitting Setup and rerunning it from Windows. If you do run Setup from MS-DOS, Setup may run slower (especially if installing from floppy disks).
