Hello everyone,

I’m trying to set up a Windows 11 VM on Unraid with iGPU passthrough (Ryzen 8600G) but having two major issues:

---

🔹 Problem 1: iGPU passthrough (real GPU)

• I’ve bound both the iGPU (graphics + audio) in Tools → System Devices → “Bind to VFIO at Boot”

• I configured the VM to use the iGPU as GPU

Result: The VM starts, Unraid GUI disappears or stays, but no video output on my monitor via HDMI/DP. Black screen.

---

🔹 Problem 2: vGPU mode (no passthrough)

• For testing I switched the VM to use vGPU (software emulated)

Result: VM launches, but instead of installing or booting Windows, I’m dumped into the UEFI Interactive Shell. No boot disk is found. Even with virtIO disk set up, the VM won’t auto-boot from disk.

---

✅ What I’ve already done

• BIOS: SVM + IOMMU enabled

• iGPU → Bind to VFIO at Boot

• tried booting with vGPU

---

❓ What I need help with

1. iGPU passthrough mode – how to get real monitor output instead of a black screen

2. vGPU mode – how to make VM boot properly from virtIO disk (still ending in UEFI shell)

---

📌 Configuration details

• Unraid version: 7.1.4

• Motherboard: ASRock B650M Riptide (BIOS 3.30)

• CPU/APU/iGPU: Ryzen 8600G

• VM Machine: i440-9.2

• BIOS for VM: OVMF / OVMF TPM (tried both

  )

• VirtIO disk bus/type: VirtIO

👋 Ask

• What am I missing to get real monitor output in iGPU passthrough? Do I need a special VBIOS or ROM?

• How can I set a persistent boot entry so the VM doesn’t drop into the UEFI shell in vGPU mode?

• Are there any known quirks with Riptide B650M + ASRock BIOS 3.30 + Ryzen 8600G?

Have you tried running the VM without the sound card?
