Valorant Vanguard Restriction Fix Guide

Seeing IOMMU, HVCI, Memory Integrity, Secure Boot, or Vanguard restriction errors? This guide walks you through the common fixes step by step.

🖼️

Check Error

Compare your popup with the common Vanguard restriction examples below.

⚙️

Enter BIOS

Restart your PC and use the correct hotkey for your motherboard or laptop brand.

🔐

Enable Security

Turn on VT-d, IOMMU, SVM, HVCI, Memory Integrity, and Secure Boot where needed.

🔄

Restart PC

Most Vanguard changes only apply properly after restarting your computer.

Before You Start

BIOS settings may look different depending on your motherboard brand and model. If you are unsure, take a photo of your BIOS screen before changing anything, or ask someone familiar with PC settings to assist.

🧩 Step 2: Enable VT-d or IOMMU

Vanguard may require virtualization-related security settings to be enabled in BIOS.

  • On Intel: Go to Advanced → CPU Configuration, then enable Intel Virtualization (VT-x) and Intel VT-d.
  • On AMD: Go to Advanced → CPU Configuration / Northbridge, then enable SVM Mode and IOMMU.
💡 After changing BIOS settings, save changes and restart your PC before trying Valorant again.

🛡️ Step 3: Enable HVCI / Memory Integrity

  1. Press Win + S and type Core Isolation.
  2. Open Core Isolation settings.
  3. Turn Memory Integrity to ON.
  4. Restart your PC.
💡 If Memory Integrity cannot be enabled, update your GPU drivers and install all available Windows Updates first.

Extra Tips

  • Enable Secure Boot in BIOS.
  • Run Valorant as Administrator.
  • Windows 10 should be version 1903+.
  • Windows 11 is generally supported, but Secure Boot / TPM / HVCI settings may still matter.

🖥️ How to Check Your Motherboard Brand and CPU

1) Check Motherboard Brand & Model

Option A – Command Prompt

  1. Press Win + R, type cmd, then press Enter.
  2. Run this command:
wmic baseboard get product,Manufacturer,version,serialnumber

This will show your motherboard manufacturer such as ASUS, MSI, Gigabyte, Dell, HP, Lenovo, or Acer, together with the product model.

2) Check Through System Information

  1. Press Win + R, type msinfo32, then press Enter.
  2. Check BaseBoard Manufacturer and BaseBoard Product.

3) Check Whether You Have Intel or AMD

  1. Right-click the taskbar and open Task Manager.
  2. Go to the Performance tab, then click CPU.
  3. Check the CPU name:
    • If it says Intel, you likely need VT-d enabled.
    • If it says AMD, you likely need SVM / IOMMU enabled.

Still Having Trouble?

If Valorant still shows a Vanguard restriction after following the guide, take a clear screenshot of the error and contact Missy Gaming so we can better understand what your PC is showing.
