To play Valorant, Secure Boot needs to be enabled in your BIOS/UEFI and your system must be using UEFI (not Legacy) with TPM turned on.

Before you change anything

  • Back up important files in case something goes wrong during boot changes.
  • Check if Secure Boot is already on:
    • Press Windows key + R → type msinfo32 → Enter.
* Look for “BIOS Mode” and “Secure Boot State”. If BIOS Mode = UEFI and Secure Boot State = On, you’re already good for Valorant.

Step 1: Make sure you’re on UEFI

If msinfo32 shows BIOS Mode: Legacy, Secure Boot will not work until you switch to UEFI and your system drive is GPT.

  • Open Disk Management → right‑click your system disk → Properties → Volumes → check Partition style (MBR or GPT).
  • If it is MBR, you normally have to convert to GPT (for many systems this can be done with tools like mbr2gpt, but using them incorrectly can break Windows; if you’re not comfortable, ask a technician or follow your motherboard/PC vendor guide).

Only continue once:

  • BIOS Mode can be set to UEFI, and
  • Your Windows actually boots in UEFI mode (shown in msinfo32).

Step 2: Enter your BIOS/UEFI

The exact key varies by brand, but the process is similar.

  1. Restart your PC.
  2. While it’s starting, repeatedly tap one of these keys until the firmware menu appears: F2, F10, F11, F12, Del, or Esc (your PC might show “Press F2/Del to enter Setup” at the bottom of the screen).

If it boots into Windows instead, retry and press the key faster or check your motherboard/manual page to confirm the correct key.

Step 3: Enable Secure Boot and TPM

Menu names differ (ASUS, MSI, Gigabyte, Dell, etc.), but the logic is consistent.

Once in BIOS/UEFI:

  • Go to the Boot or Boot Options tab.
  • Ensure “Boot Mode” / “Boot Protocol” / “BIOS Mode” is set to UEFI, not Legacy or CSM.
  • Find Secure Boot (often under Boot or Security) and set it to Enabled.
  • Go to the Security , Trusted Computing , or Advanced tab and turn on TPM / fTPM / PTT:
    • Intel systems: look for “PTT” or “Intel Platform Trust Technology” and enable it.
* AMD systems: look for “fTPM” or “AMD fTPM” and enable it.

Some BIOS will also ask about Secure Boot keys:

  • If you see “Key Management” or “Install default keys”, choose to load or install default keys so Secure Boot can actually function.

Then:

  • Go to the “Save & Exit” menu.
  • Choose “Save changes and exit” (often F10) and confirm.

Your PC will reboot with Secure Boot enabled.

Step 4: Confirm and launch Valorant

Back in Windows:

  • Open msinfo32 again and confirm:
    • BIOS Mode: UEFI
    • Secure Boot State: On.

If both are correct and TPM is enabled, Valorant’s Vanguard anti‑cheat should stop showing the Secure Boot / TPM error and the game should launch normally.

Common issues Valorant players report

From forum and tech‑support discussions:

  • Secure Boot option is greyed out:
    • Often means the system is in Legacy/CSM boot mode or the drive is still MBR, so the firmware refuses to enable Secure Boot.
  • Black screen when entering advanced/BIOS:
    • Some users report needing to update BIOS or use a different key/entry method (like “UEFI Firmware Settings” from Windows’ Advanced Startup).
  • Game still complains after enabling:
    • Double‑check that TPM is enabled and that Secure Boot State is actually “On,” not just “Supported”.
