- Follow the steps in this post: How to create an MS DOS virtual box.
- Reboot the virtual machine. It should start MS DOS and load the CD driver
- Next insert the Windows 3.11 iso image into the CD ROM drive
- Change to the CD ROM by giving the "d:" command (assuming you mounted the CD ROM on d:)
- Run the SETUP.EXE program
- About 15 seconds later Windows 3.11 will be installed.
I recommend powering down this virtual machine and copying it somewhere so that it can be the basis for a Windows 95 upgrade install or a Windows 98 upgrade install.
