Virtual machines have become an essential tool for developers, IT professionals, students, and everyday users who want to run multiple operating systems on a single computer. Instead of purchasing separate hardware, a virtual machine (VM) allows you to create a complete computer environment within your existing Windows 11 system. You can install another version of Windows, run Linux distributions, test software, practice system administration, or experiment with settings without affecting your primary operating system.
One of the best virtualization solutions available in Windows 11 is Hyper-V. Developed by Microsoft, Hyper-V is built directly into Windows 11 Pro, Enterprise, and Education editions. It provides enterprise-grade virtualization features while remaining easy enough for home users to learn. Once Hyper-V is enabled, you can create virtual machines, assign memory and storage, connect them to networks, and install operating systems just like you would on a physical computer.
In this guide, you’ll learn how to create a virtual machine in Hyper-V on Windows 11, configure its settings, install an operating system, and optimize it for the best performance.
What Is a Virtual Machine?
A virtual machine is a software-based computer that runs inside your physical computer.
A virtual machine includes:
- Virtual CPU
- Virtual memory (RAM)
- Virtual hard disk
- Virtual network adapter
- Virtual motherboard
- Operating system
From the operating system’s perspective, the virtual machine behaves like a real computer.
Common uses include:
- Testing software
- Learning Linux
- Running older operating systems
- Security research
- Application development
- Training environments
- Running isolated workloads
Requirements Before Creating a Virtual Machine
Before creating a VM, make sure:
- Hyper-V is enabled.
- Hardware virtualization is enabled in BIOS/UEFI.
- You have sufficient RAM.
- You have enough free storage space.
- You have an operating system ISO file.
Recommended resources:
- 8 GB RAM minimum
- 16 GB RAM or more preferred
- 50 GB or more free storage
- Multi-core processor
The better your hardware, the smoother your virtual machines will run.
Method 1: Open Hyper-V Manager
The first step is launching Hyper-V Manager.
Steps:
- Open the Start menu.
- Search for Hyper-V Manager.
- Open the application.
- Select your computer name in the left panel.
Hyper-V Manager serves as the central console for creating and managing virtual machines.
If Hyper-V Manager does not appear, verify that Hyper-V has been enabled and restart your PC.
Method 2: Create a Virtual Switch
A virtual switch allows your virtual machine to access the network and internet.
Steps:
- Open Hyper-V Manager.
- Click Virtual Switch Manager.
- Select External.
- Click Create Virtual Switch.
- Enter a switch name.
- Select your active network adapter.
- Click Apply.
- Click OK.
This creates a network bridge between your virtual machine and your physical network connection.
Without a virtual switch, internet access inside the virtual machine may not function properly.
Method 3: Start the New Virtual Machine Wizard
Hyper-V includes a wizard that simplifies VM creation.
Steps:
- Open Hyper-V Manager.
- Select your computer.
- Click New.
- Choose Virtual Machine.
- Click Next.
The New Virtual Machine Wizard will guide you through the setup process.
This wizard is suitable for both beginners and advanced users.
Method 4: Name the Virtual Machine
Every virtual machine should have a meaningful name.
Steps:
- Enter a name for the VM.
- Optionally choose a custom storage location.
- Click Next.
Examples:
- Windows 11 Test
- Ubuntu Lab
- Linux Server
- Software Testing VM
- Development Environment
Choosing descriptive names helps when managing multiple virtual machines.
Method 5: Choose the Virtual Machine Generation
Hyper-V offers two VM generations.
Generation 1
Best for:
- Older operating systems
- Legacy software
- Older hardware compatibility
Generation 2
Best for:
- Windows 10
- Windows 11
- Modern Linux distributions
- UEFI support
- Secure Boot support
For most users, Generation 2 is the recommended option.
Select your preferred generation and click Next.
Method 6: Assign Memory to the Virtual Machine
Memory allocation determines how much RAM the VM can use.
Steps:
- Enter the startup memory value.
- Enable Use Dynamic Memory if desired.
- Click Next.
Suggested memory allocations:
| Operating System | Recommended RAM |
|---|---|
| Windows 11 | 4096 MB – 8192 MB |
| Windows 10 | 4096 MB |
| Ubuntu | 2048 MB – 4096 MB |
| Linux Server | 1024 MB – 2048 MB |
Dynamic Memory allows Hyper-V to automatically adjust memory usage when needed.
This helps optimize overall system performance.
Method 7: Configure Networking
Now connect the virtual machine to your virtual switch.
Steps:
- Select the virtual switch created earlier.
- Click Next.
This enables:
- Internet access
- Network communication
- Shared resources
- Remote connectivity
If you skip this step, networking can be configured later.
Method 8: Create a Virtual Hard Disk
The virtual hard disk stores the operating system and files.
Steps:
- Choose Create a virtual hard disk.
- Enter a disk name.
- Specify the storage size.
- Click Next.
Recommended sizes:
- Windows 11: 64 GB or more
- Windows 10: 50 GB or more
- Ubuntu: 25 GB or more
- Linux Server: 20 GB or more
Hyper-V creates a VHDX file that functions like a physical hard drive.
You can expand the storage later if needed.
Method 9: Install an Operating System
Now choose the operating system installation source.
Steps:
- Select Install an operating system from a bootable image file.
- Browse to your ISO file.
- Select the ISO.
- Click Next.
Examples:
- Windows 11 ISO
- Windows 10 ISO
- Ubuntu ISO
- Debian ISO
- Fedora ISO
Review the summary and click Finish.
The virtual machine is now created.
Method 10: Start and Install the Operating System
Once the VM has been created, you can install the operating system.
Steps:
- Right-click the virtual machine.
- Select Connect.
- Click Start.
- Wait for the VM to boot from the ISO.
- Follow the operating system installation wizard.
Installation proceeds similarly to installing Windows or Linux on a physical computer.
After setup completes, your virtual machine is ready to use.
Adjust Virtual Machine Settings
After creating the VM, you may want to customize it further.
Change Processor Count
- Right-click the VM.
- Select Settings.
- Choose Processor.
- Increase CPU cores if necessary.
Increase Memory
- Open Settings.
- Select Memory.
- Adjust RAM allocation.
Add Additional Storage
- Open Settings.
- Select SCSI Controller.
- Add another virtual hard disk.
Modify Network Settings
- Open Network Adapter settings.
- Select a different virtual switch if needed.
These adjustments can improve VM performance depending on workload requirements.
