Fix Valorant Error VAN9003 - Enable Secure Boot and TPM 2.0

If you are staring at a VAN9003 error, your PC's security settings are currently blocking Riot Vanguard from launching. This is frustrating because it usually means your system is running in an older boot mode that Valorant no longer accepts. You need to adjust your motherboard firmware to bring your system up to current Windows 11 requirements.

Why this happens

Riot Vanguard requires Secure Boot and TPM 2.0 to be active to ensure your system integrity. If your PC is set to Legacy BIOS mode or these security features are disabled in your firmware, the game will refuse to start.

What you will need

You will need to restart your computer and access your BIOS or UEFI menu. Have your keyboard ready to press the required key immediately upon power-up.

Steps

1. 01
   Press the Windows key + R, type msinfo32, and press Enter to check your current BIOS Mode and Secure Boot State.
2. 02
   Press the Windows key + R, type tpm.msc, and press Enter to confirm your TPM status.
3. 03
   Restart your computer and immediately tap your BIOS entry key (usually Delete, F2, F10, F11, or F12).
4. 04
   Navigate to your Boot settings, set the Boot Mode to UEFI, and disable CSM or Legacy support.
5. 05
   Go to the Security or Advanced tab and set Secure Boot to Enabled.
6. 06
   Locate the TPM, AMD fTPM, or Intel PTT setting and set it to Enabled.
7. 07
   Press F10 to save your changes and exit the BIOS, which will automatically restart your computer.
8. 08
   Launch Valorant to verify the game now proceeds to the main menu.
