In this tutorial, we will look at how to install Windows 11 on Proxmox.
The process to install Windows 11 on Proxmox is extremely similar to most other virtual machine installations on Proxmox. The main difference is setting up and configuring TPM, which we will walk through below. It’s always a good idea to ensure that Proxmox is up to date, which as of the writing of this article is v7.3-6. Also, please check out our tutorial on GPU passthrough if you’re interested in configuring that!
How to Install Windows 11 on Proxmox
We will look at how to install Windows 11 on Proxmox below, but there are a few prerequisites that must be downloaded first.
- Download the latest Windows 11 ISO and upload it to Proxmox.
- Download the latest VirtIO Drivers and upload them to Proxmox (under the installation section).
After the ISO images above have been downloaded, move on to the next steps to learn how to install Windows 11 on Proxmox.
1. Select Create VM to create a new virtual machine.
2. Enter the VM ID and Name, then select Next.
3. In the OS section, select the Windows 11 ISO image. Under Guest OS, make sure that Microsoft Windows and 11/2022 are selected. Then select Next.
4. In the System section, the default values are generally fine, but there are a few changes we need to make. Select the same storage location for the TPM Storage and EFI Storage that you intend on using for the disk. Select QEMU Agent, then ensure that q35 and OVMF (UEFI) are selected.
5. In the Disks section, select the storage type you’d like to use, then set the Disk Size as at least 64GB (this is the minimum Microsoft recommends for Windows 11, but you can always increase it later).
6. Set the CPU, Memory, and Network settings to whatever you’d like (even using a VLAN if you’d like), then confirm the settings and select Finish. Make sure that the VM does not start after creation!
7. After the VM is created, select it, then select Hardware. Add a new CD/DVD Drive with the VirtIO Drivers downloaded earlier. After the drive has been added, Start the virtual machine!
Installing Windows 11 on Proxmox
Now that Proxmox has been configured, we will run through the steps on how to install Windows 11 on Proxmox. The key is ensuring that the correct drivers are utilized during the installation.
1. Boot up the VM and access the Windows Setup (you might have to press a key to boot into the Windows installation when first starting the virtual machine). Select the correct settings, then select Next.
2. Select Install Now and the installation will begin.
3. Add a Product Key if you have one, or select I don’t have a product key.
4. Select the version of Windows 11 you’d like to install, then select Next.
5. Accept the terms (if you agree with them), then select Next.
6. Select Custom as we will have to install the correct drivers before proceeding.
7. The drivers will not be installed by default meaning that the Install Windows screen below will initially be blank. To install the drivers, select Load Driver, browse to the VirtIO disk, select amd64, then w11, and finally, OK.
8. Windows should find the correct Driver. If it did, select Next to install it.
9. After it’s installed, you’ll see the hard drive selected. You can now proceed and Windows will install! After the installation, the VM will reboot.
Windows 11 Setup – How to Install Windows 11 on Proxmox
Now that Windows 11 is installed, the final step is to configure it. I am not going to provide screenshots for this as it’s a basic Windows 11 configuration.
- Select the Country and Keyboard, then proceed. Windows 11 will start to check for updates.
- Add a PC name. After adding a PC name, the VM will restart.
- Set up the device for personal use or work/school.
- Sign in to your Microsoft Account.
- Set up a PIN.
- Choose your Privacy settings.
- Customize your experience, then determine if you’d like to configure Android access.
- Determine if you’d like to use a free trial of Microsoft 365 and Microsofts Game Pass.
Finally, Windows will search for updates, then get the system ready. When complete, you’ll see the Windows 11 desktop!
If you open the Device Manager, you will notice that a few drivers must be installed, so that’s the final step.
VirtIO Driver Installation
1. Open the VirtIO CD Drive (it should still be mounted). Double-Click the virtio-win-gt-x64.msi file to run the installer.
2. Run the installer, ensure that everything is selected, then select Next to install the drivers.
3. After the installation is complete, all drivers should be successfully installed and Windows 11 should be fully functional!
Conclusion: Installing Windows 11 on Proxmox
This tutorial looked at how to install Windows 11 on Proxmox. Overall, the process is very similar to other types of installations, with the exception being the TPM configuration and driver installation. As long as you set both of those up properly, you’ll have a fully functional Windows 11 virtual machine!
