Windows 11 VM in Proxmox — volledige configuratie

A complete walkthrough for setting up a Windows 11 virtual machine in Proxmox that satisfies all the required hardware checks (TPM 2.0, Secure Boot, UEFI).

Prerequisites¶

• Proxmox VE 7.0 or newer
• Windows 11 ISO file
• Virtio drivers ISO (optional but recommended)

Step 1 — Create a New VM¶

• Log in to your Proxmox web interface.
• Click Create VM in the top right.
• In the General tab: enter a VM ID (or leave as default) and a name (e.g. “Windows11”). Click Next.

Step 2 — OS Settings¶

• In the OS tab: select Microsoft Windows as the Guest OS type, Version 11/2022. Click Next.

Step 3 — System Settings (critical for Windows 11)¶

• In the System tab:
• Machine: “q35” (newer than i440fx)
• BIOS: “OVMF (UEFI)”
• Check Add EFI Disk (for Secure Boot support)
• SCSI Controller: “VirtIO SCSI”
• Check Qemu Agent
• Click Next

Step 4 — Disk Settings¶

• In the Disk tab:
• Bus/Device: “SCSI”
• Disk size: at least 64 GB
• Format: “qcow2”
• Click Next

Step 5 — CPU Settings¶

• In the CPU tab:
• Sockets: 1
• Cores: at least 2
• Type: “host” (required for Windows 11 CPU checks)
• Click Next

Step 6 — Memory Settings¶

• In the Memory tab:
• RAM: at least 4096 MB (4 GB)
• Keep the Ballooning device enabled
• Click Next

Step 7 — Network Settings¶

• In the Network tab:
• Bridge: “vmbr0” (or your network bridge)
• Model: “VirtIO (paravirtualized)”
• Click Next

Step 8 — Confirm Settings¶

• Review all settings and click Finish. Do NOT start the VM yet.

Step 9 — Add TPM 2.0 (required)¶

• Select the VM in the left panel.
• Open the Hardware tab.
• Click Add → TPM State.
• Set Version to v2.0, choose storage for the TPM state and click Add.

Step 10 — Add the Windows 11 ISO¶

• Select the VirtIO drivers ISO.

Step 11 — Enable Secure Boot (required)¶

• Go to the Options tab.
• Under Boot Order: make sure the CD/DVD drive is first, the hard disk second, and the EFI disk is included.
• Under SMBIOS Settings: set Manufacturer to “Microsoft”.

Step 12 — Install Windows 11¶

• Start the VM; the Windows installation should begin.
• Follow the standard Windows 11 installation steps.
• If prompted for drivers (disk detection), load them from the VirtIO ISO if you added it.

Step 13 — Bypass TPM/Secure Boot Check (alternative method)¶

If you still have issues with the TPM/Secure Boot checks, use the registry bypass method:

• On the first Windows 11 setup screen, press Shift+F10 to open Command Prompt.
• Type regedit and press Enter.
• Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\Setup
• Create a new key named LabConfig.
• In the LabConfig key, create the following DWORD (32-bit) values:
• BypassTPMCheck = 1
• BypassSecureBootCheck = 1
• BypassRAMCheck = 1
• Close the Registry Editor and continue the installation.

Step 14 — Post-Installation¶

• Install the Proxmox guest tools.
• Install any necessary VirtIO drivers if using VirtIO devices.

Troubleshooting¶

• “This PC can’t run Windows 11”: double-check TPM 2.0 and Secure Boot settings.
• Disk not detected: load the VirtIO SCSI drivers during installation.
• Poor performance: install the QEMU guest agent and VirtIO drivers.
• Installation hangs: try increasing RAM or changing the CPU type.
