Install Windows 3.1 on Virtual Machine (The Ultimate Guide)
If you’re looking to set up a Windows 3.1 virtual machine on Windows, you’re in the right place. Whether you’re feeling nostalgic, testing legacy software, or just curious about how computing looked back in the early ’90s, this guide will walk you through the entire process of setting up Windows 3.1 in a virtual machine on Windows —even if you’re not tech-savvy.
And guess what? We’re not just going to install Windows 3.1. We’re going to optimize it, troubleshoot issues, and make sure everything runs smoothly. By the end, you’ll have a fully functional Windows 3.1 environment running on your modern PC. Let’s dive in!
Why Install Windows 3.1 on a Virtual Machine?
Before diving into the setup, let’s talk about why you’d even want to install Windows 3.1 in 2025.
1. Nostalgia and Retro Gaming
Windows 3.1 was a game-changer back in the day. If you grew up in the ’90s, you probably remember playing classic DOS games or using early versions of Microsoft Office. A virtual machine lets you relive that experience without needing old hardware.
2. Running Legacy Software
Some businesses and researchers still rely on older Windows applications that don’t run natively on modern operating systems. Virtual machines provide a way to keep these programs running.
3. Learning and Experimentation
Want to understand how Windows evolved? Installing Windows 3.1 can give you hands-on experience with one of Microsoft’s earliest graphical operating systems.
Alright, now that we know why, let’s talk about what you’ll need.

What You Need to Get Started?
To install Windows 3.1, you’ll need a few things:
A Virtual Machine Software: We’ll use VirtualBox (free) or VMware (paid option).
Windows 3.1 Installation Files: You’ll need the original floppy disk images or ISO files (Google is your friend here).
MS-DOS 6.22: Windows 3.1 runs on top of MS-DOS, so we need to install DOS first.
A Modern Windows 11 PC: To host the virtual machine.
Once you have these, let’s move on to installation!
Step 1: Install Virtual Machine Software
First, we need to install virtualization software. You have two great options: Oracle VirtualBox and VMware Workstation Player.
VirtualBox: A free and open-source virtualization tool that’s widely used and well-documented. It works on Windows, macOS, and Linux, making it a versatile choice.
VMware Workstation Player: A more polished and user-friendly alternative to VirtualBox. VMware is known for its stability, performance, and additional features, but the free version has some limitations compared to VirtualBox
You can choose any of the applications that you feel comfortable with. For now, we are going to select VirtualBox and install Windows 3.1 inside.
Step 2: Create a New Virtual Machine
Here you are going to create a new virtual machine:
1. Click New in VirtualBox (or VMware) to create a new VM.
2. Name the new VM as “Windows 3.1” and select Type: Microsoft Windows and Version: Windows 3.1.
3. Allocate at least 512MB RAM (Windows 3.1 needs way less, but more won’t hurt).
4. Create a 2GB Virtual Hard Disk & choose VDI (VirtualBox Disk Image). Don’t forget to select the Fixed Size option.
5. Click Create and wait for the virtual disk to be generated.
Now, we’re ready to install DOS before moving to Windows 3.1.
Step 3: Install MS-DOS
Since Windows 3.1 isn’t a standalone OS—it runs on MS-DOS. Here’s how to install it:
- Download an MS-DOS bootable ISO (https://www.itechscreen.com/download/Microsoft-ms-dos).
- Go to VirtualBox > Settings > Storage and load the DOS ISO into the virtual CD drive.
- Start your VM and boot from the ISO.
- Follow the prompts to install DOS on your virtual hard drive.
After the DOS installation, remove the ISO from the virtual drive and reboot the VM. Now we’re set to install Windows 3.1.
Step 4: Install Windows 3.1
Now that your virtual machine is set up, it’s time to install Windows 3.1. Follow these steps carefully to ensure a smooth installation process:
1. Mount the Windows 3.1 ISO File
- Open VirtualBox and select your Windows 3.1 virtual machine.
- Click Settings and navigate to the Storage tab.
- Under the Controller: IDE section, click the empty CD/DVD icon.
- On the right side, click the Choose a disk file option and locate your Windows 3.1 ISO file.
- Select the ISO file and click OK to save the settings.
2. Start the Virtual Machine
- Click Start to boot up your Windows 3.1 virtual machine.
- The system should automatically detect the ISO file and launch the installation process.
3. Begin the Installation
- Once the setup screen appears, follow the on-screen prompts to begin the installation.
- Press Enter when prompted to start the setup.
- Choose a directory for Windows installation (default is “C:\WINDOWS” – you can leave this as is and press Enter).
4. Follow Setup Instructions
- The setup will ask if you want to install Windows 3.1 in Enhanced Mode or Standard Mode. Choose Enhanced Mode for better compatibility.
- Proceed with the installation by following the prompts. The system may copy files and ask for confirmation at various stages.
- Once the file copying is complete, the installer will prompt you to enter personal details like name and organization (you can input any name).
- After entering the details, the setup will configure display settings, mouse, and other basic system components.
5. Complete the Installation
After installation finishes, you may be asked to restart the virtual machine.
Once restarted, Windows 3.1 should boot up, displaying the classic Program Manager interface. You’re now ready to use Windows 3.1 in a virtual environment!
Step 5: Optimize Your Windows 3.1 Virtual Machine
Now that Windows 3.1 is installed, let’s make it better:
Increase screen resolution: Install the S3 Graphics Driver for a better display.
Improve sound: Use the SoundBlaster 16 driver for proper audio.
Enable file sharing: Set up a shared folder between Windows 3.1 and Windows 11.
Install Win32s: This allows Windows 3.1 to run some 32-bit applications.
Troubleshooting Common Issues
Issue: Windows 3.1 won’t boot.
– Make sure MS-DOS is properly installed.
– Check that the virtual hard disk is mounted.
Issue: No sound in Windows 3.1?
– Install SoundBlaster 16 drivers inside Windows 3.1.
Issue: Low screen resolution?
– Install the S3 video driver for a better display.
