This Valorant UEFI Secure Boot Error is a common issue for Windows 11 players. Valorant’s anti-cheat (Vanguard) requires two specific security features to be active: TPM 2.0 and Secure Boot.

If either is off, you will get error codes like VAN 9001 or VAN 9003.

Here is the step-by-step fix.

Please read Step 1 carefully to avoid boot issues.

Step 1: The Safety Check (Do Not Skip)

Before you change any settings in your BIOS, you must ensure your Windows drive is formatted correctly. If you switch to “Secure Boot” on an older drive format (MBR), your computer will not boot.

1. Press Windows Key + R.

2. Type msinfo32 and press Enter.

3. Look for BIOS Mode:

   • If it says UEFI, you are safe to proceed to Step 2.

   • If it says Legacy, you cannot enable Secure Boot yet. You must convert your drive from MBR to GPT first. (Search for “MBR to GPT conversion” before proceeding, or you will lose access to Windows).

Step 2: Enter Your BIOS

1. Restart your computer.

2. As soon as it turns on, spam the BIOS key repeatedly.

   • ASUS / MSI / Gigabyte: Del or F2

   • HP / Dell: F10 or F12

Step 3: Enable Secure Boot (Brand-Specific Steps)

Once in the BIOS, the interface varies by brand. Find your manufacturer below:

For Gigabyte

1. Go to the Boot tab.

2. Find CSM Support and set it to Disabled. (Secure Boot will not show up if CSM is enabled).

3. Scroll down to Secure Boot and toggle it to Enabled.

4. Note: If it says “Not Active,” look for Secure Boot Mode > change to Standard.

5. Press F10 to Save & Exit.

For ASUS

1. Press F7 for Advanced Mode.

2. Go to the Boot tab > Secure Boot.

3. Change OS Type to Windows UEFI Mode.

4. If Secure Boot is still grayed out, go back to the Boot tab, find CSM (Compatibility Support Module), and set it to Disabled.

5. Press F10 to Save & Exit.

For MSI

1. Press F7 for Advanced Mode.

2. Go to Settings > Advanced > Windows OS Configuration.

3. Change BIOS UEFI/CSM Mode to UEFI.

4. Go to Secure Boot and set it to Enabled.

5. Note: If it complains about “Keys,” select Secure Boot Mode > Custom, then click Restore Factory Keys (or “Enroll all Factory Default Keys”).

6. Press F10 to Save & Exit.

For ASRock

1. Go to Security or Boot.

2. Disable CSM.

3. Enable Secure Boot.

4. If it says “Install default Secure Boot keys,” click that option.

Step 4: Verify in Windows

1. Boot back into Windows.

2. Press Windows Key + R, type msinfo32, and hit Enter.

3. Check Secure Boot State. It should now say On.

4. Launch Valorant.

Troubleshooting: “I enabled it but it still says Off”

If you enabled Secure Boot in BIOS but Windows still says “Off”:

1. Go back to BIOS > Secure Boot.

2. Look for an option called “Restore Factory Keys” or “Install Default Keys”.

3. Click it, save, and restart. Secure Boot requires these keys to be active to function.
