To fix Valorant VAN 9003, enable Secure Boot and UEFI mode in your motherboard BIOS settings immediately.

Quick BIOS Solution

To fix the Valorant VAN 9003 error, enable UEFI and Secure Boot within your computer's motherboard BIOS/UEFI firmware settings instantly.

# Step 1: Access Motherboard UEFI/BIOS

1. Save your progress and restart your computer. 2. As the screen goes black, tap the BIOS hotkey repeatedly (usually F2, Del, or F12 depending on your motherboard brand like ASUS, MSI, Gigabyte, or ASRock).

# Step 2: Enable UEFI Mode

Secure Boot requires UEFI mode instead of legacy CSM. 1. Navigate to the Boot or Security tab. 2. Locate Boot Mode or CSM (Compatibility Support Module). 3. Set CSM to Disabled and ensure Boot Mode is set fully to UEFI Only.

# Step 3: Enable Secure Boot & TPM 2.0

Windows 11 and Valorant Vanguard strictly require Secure Boot active: 1. In the Boot or Security configurations, find Secure Boot. 2. Toggle its status to Enabled (if it says "Custom", change the key management status to "Standard" or "Install Default Keys"). 3. Navigate to Peripherals, Advanced, or Security to locate Intel Platform Trust Technology (IPTT) or AMD CPU fTPM and set it to Enabled. 4. Press F10 to save settings and reboot your Windows system.

# Verification of Settings

Open your browser, launch Valorant, and connect to matches without further VAN 9003 blocks.
