If you’re trying to launch Call of Duty: Black Ops 7 on PC and keep getting errors related to Secure Boot, you’re not alone. Activision now requires Secure Boot to be enabled for anti-cheat protection, and many players don’t realize their PC has it turned off by default.

This guide will show you exactly how to turn on Secure Boot so you can install, launch, and play Black Ops 7 without issues.

What Is Secure Boot and Why Black Ops 7 Requires It

Secure Boot is a security feature built into modern PCs that prevents unauthorized software from running during startup.
For Black Ops 7, Secure Boot helps:

• Block cheat loaders
• Protect the game’s anti-tamper system
• Maintain competitive integrity
• Ensure a secure Windows boot environment

If Secure Boot is disabled, Black Ops 7 may refuse to launch or display an error message.
How to Check If Secure Boot Is Enabled

Before changing anything, check your current status.

Windows 10 & Windows 11

1. Press Windows Key + R
2. Type: msinfo32
3. Press Enter
4. Look for Secure Boot State

You’ll see one of three results:

• On — You’re good; Black Ops 7 will run.
• Off — You need to enable it.
• Unsupported — Usually caused by Legacy/CSM Mode being enabled.

If Secure Boot is “unsupported,” don’t worry—you can still fix it.

How to Enable Secure Boot on Your PC (Step-by-Step)

Secure Boot is controlled through your computer’s BIOS/UEFI settings.

Step 1: Restart your PC

Click Restart while holding Shift to enter advanced startup options.
Or simply reboot normally and use your motherboard key:

• DEL
• F2
• F10
• ESC

(The key varies depending on brand.)

Step 2: Enter BIOS/UEFI Setup

Once your PC restarts, enter the BIOS menu.

Common BIOS names: ASUS UEFI, MSI Click BIOS, Gigabyte UEFI, Dell/HP Firmware Menu.

Step 3: Disable Legacy Boot (If Enabled)

Secure Boot won’t activate unless your system is in UEFI mode.

Look for options like:

• Legacy Boot → Disable
• CSM Support → Disable
• Boot Mode → UEFI Only

After switching to UEFI, save and reboot back into BIOS.

Step 4: Locate Secure Boot Setting

Usually found under:

• Boot
• Security
• Advanced
• Authentication

Look for:

Secure Boot → Enable

If key management is required:

Select Install Default Keys or Standard Keys

Step 5: Save Settings

Press:

• F10 → Save & Exit

Verify Secure Boot Is On

After reboot:

1. Press Windows Key + R
2. Type: msinfo32
3. Look for Secure Boot State → On

If it shows “On,” you’re ready to launch Black Ops 7.
