Valorant UEFI Secure Boot Fix: Eliminate VAN 9001 & VAN 9003 Errors Fast

VAN 9001 and VAN 9003 errors in Valorant appear when Riot Vanguard detects missing security requirements, making this a common Valorant Secure Boot error fix scenario. Systems running without UEFI Secure Boot or TPM 2.0 get blocked at launch, similar to how the game rejects modified drivers or unsigned files during competitive matchmaking.

Valorant UEFI Secure Boot Setup Guide

The system boot process includes Vanguard to block cheating methods that use memory injectors and driver-based exploits. Secure Boot prevents unsigned bootloaders from running while TPM 2.0 secures hardware identity through its protective measures. The system needs these components to function because it now operates as an unverified client who attempts to rank up using a modified game file.

Steps to Fix the Issue:

Step 1: Check System Configuration

• Press Windows + R → type msinfo32.
• Verify: BIOS Mode → UEFI then Secure Boot State → On.
• Legacy mode is a traditional thing and it immediately fails Vanguard's validation upon activation.

Step 2: Access BIOS/UEFI

• Restart and press DEL / F2 / F10 / ESC during boot.
• On Windows: Settings → Recovery → Advanced Startup → UEFI Firmware Settings.

Step 3: Enable Secure Boot

• Set Boot Mode → UEFI
• Disable CSM
• Enable Secure Boot → Standard Mode
• Save and restart

Configuration Support Manager (CSM) behaves as a fallback system enabling active mirrors to be allowed to run unsupported configs in a ranked environment.

Step 4: Enable TPM 2.0

• Run tpm.msc to check status (Vanguard TPM 2.0 requirement fix)

If disabled: Intel → Enable PTT & AMD → Enable fTPM
TPM is this hardware verification layer that is like account authentication in matchmaking queues.

Step 5: Check Drive Format (GPT Required)

• Open Disk Management → Properties → Volumes
• Confirm Partition Style → GPT
• MBR disables the boot of UEFI SAFE mode in Valorant. Convert it using MBR2GPTautor.

Extra Fixes & Error Code Reference

• Update BIOS firmware.
• Reset Secure Boot keys.
• Disable Fast Boot.
• Run sfc /scannow and DISM.
• Reinstall Vanguard.

Here are some of the:

• VAN 9001 → Secure Boot disabled.
• VAN 9003 → TPM 2.0 disabled.
• VAN 9090 → TPM initialization failure.

Previous systems provided users with adaptability, but present enforcement mechanisms restrict player behavior to predetermined Killjoy and Cypher gameplay patterns. The UEFI Secure Boot system in Valorant creates cleaner competitive matches which match the precise gameplay experience of Valorant's Top 5 Best Marshal Skins.
