The usual fix is to enable the existing firmware TPM—Intel PTT on many Intel systems or AMD CPU fTPM on many AMD systems—then ensure Windows is using UEFI boot mode with a GPT system disk before turning on Secure Boot.
Short answer: Black Ops 7 on PC requires both TPM 2.0 and Secure Boot. You usually do not need to buy a TPM module: Intel PCs commonly use Intel Platform Trust Technology (PTT), while AMD PCs commonly use AMD CPU fTPM. Before enabling Secure Boot, Windows must also be installed in UEFI mode on a GPT system disk.

The safest order is:
- Check TPM 2.0, BIOS mode, Secure Boot state, and disk partition style in Windows.
- Enter UEFI/BIOS through Windows Advanced Startup.
- Enable Intel PTT, AMD fTPM, or the equivalent firmware TPM setting.
- Convert an MBR system disk to GPT only if necessary, and validate it first.
- Switch to UEFI mode and enable Secure Boot.
- Boot back into Windows and verify all requirements before launching the game.
What Black Ops 7 requires on PC
Activision lists TPM 2.0 and Secure Boot as required for Call of Duty: Black Ops 7 on PC. The supported operating systems listed by Activision are Windows 10 version 22H2 or later and Windows 11, but an eligible Windows version alone is not enough. The PC must also meet the firmware and disk-layout requirements.

| Requirement | What you should see |
|---|---|
| TPM | TPM is ready for use and reports specification version 2.0 |
| Firmware mode | BIOS Mode: UEFI |
| System disk | GPT partition style, not MBR |
| Secure Boot | Secure Boot State: On |
| Operating system | Windows 10 version 22H2 or later, or Windows 11 |
TPM and Secure Boot are related but separate. Enabling Secure Boot does not automatically enable TPM 2.0, and enabling TPM does not switch a Legacy/MBR installation to UEFI/GPT.

Before changing UEFI or BIOS settings
Back up important files before changing firmware settings or converting a system disk. An incorrect UEFI/BIOS change can make Windows fail to boot. Use the support documentation for your exact PC or motherboard model because menu names and available options vary considerably between manufacturers.
If you are not comfortable changing firmware settings, use your motherboard manufacturer’s BIOS guide before proceeding. Activision also recommends manufacturer or professional assistance when you are unfamiliar with UEFI/BIOS configuration.
Step 1: Check whether TPM 2.0 is already enabled
- Press Windows + R.
- Type
tpm.mscand press Enter. - Check the status and specification version in the TPM Management window.
A compliant result should indicate that the TPM is ready for use and identify the Specification Version as 2.0.
If Windows says that a compatible TPM cannot be found, the TPM may simply be disabled in UEFI/BIOS. It can also mean that the PC does not support TPM 2.0. Do not assume that you need to purchase a discrete TPM module: many systems already include a firmware TPM, and an add-in module must be specifically compatible with the motherboard.
Step 2: Check BIOS mode and Secure Boot state
- Press Windows + R.
- Type
msinfo32and press Enter. - In System Information, find BIOS Mode.
- Find Secure Boot State.
For Black Ops 7, the target results are:
- BIOS Mode: UEFI
- Secure Boot State: On
If BIOS Mode already says UEFI, you can proceed to check the disk partition style and then enable Secure Boot. If it says Legacy, do not switch the firmware to UEFI yet. First determine whether the Windows system disk uses MBR or GPT.
Step 3: Check whether the system disk uses GPT
Secure Boot requires a UEFI-style Windows installation. In practice, that normally means the system disk uses GPT rather than the older MBR partition style.
To check:
- Right-click the Start button and open Disk Management.
- Right-click the disk containing the Windows installation, usually Disk 0, in the lower disk map.
- Select Properties, then open the Volumes tab.
- Check Partition style.
You want to see GUID Partition Table (GPT). If the disk says Master Boot Record (MBR) and msinfo32 reports Legacy BIOS mode, do not change Legacy/CSM to UEFI immediately. Windows may stop booting because the installation and firmware mode no longer match.

- PIN DEFINE:14Pin
- Interface:LPC
- Please check the Pinout of mainboard at the official website and make sure it compatible with the pinout of TPM module before purchasing, thank you.
Step 4: Enter UEFI/BIOS from Windows
Windows can restart directly into the firmware menu, avoiding the need to guess which key to press during startup.
Windows 11
- Open Settings > System > Recovery.
- Next to Advanced startup, select Restart now.
- Choose Troubleshoot > Advanced options > UEFI Firmware Settings > Restart.
Windows 10
- Open Settings > Update & Security > Recovery.
- Next to Advanced startup, select Restart now.
- Choose Troubleshoot > Advanced options > UEFI Firmware Settings > Restart.
The firmware interface is different on every manufacturer’s system. If UEFI Firmware Settings is missing, the PC may be using Legacy BIOS, the firmware may not expose the option through Windows, or the manufacturer may require a startup hotkey such as a model-specific function key. Check the exact PC or motherboard manual rather than guessing.
Step 5: Enable TPM 2.0 in UEFI/BIOS
Look in sections named Advanced, Security, Trusted Computing, or a similar security-related menu. The setting is usually a firmware TPM, not a physical chip that you need to install.
Intel systems
Look for one of these names:
- Intel PTT
- Intel Platform Trust Technology
- Security Device Support
- TPM Device or a similar firmware TPM option
Set the relevant option to Enabled.
AMD systems
Look for one of these names:
- AMD CPU fTPM
- Firmware TPM
- AMD fTPM configuration
- Security Device Support
Set the relevant option to Enabled. On some ASUS systems, for example, the illustrative path is Advanced > AMD fTPM configuration > Enable Firmware TPM. That path is not universal.
Some computers provide a discrete TPM option instead. That is one possible implementation, not a requirement to buy a module. A discrete module is motherboard-specific and should not be purchased unless the manufacturer confirms compatibility and the system genuinely lacks a usable firmware TPM.
Save the change, exit UEFI/BIOS, and allow Windows to start. Run tpm.msc again. Confirm that the TPM is ready for use and reports version 2.0.
Step 6: Convert MBR to GPT only when necessary
Skip this step if the system disk is already GPT and msinfo32 already reports UEFI. If the disk is MBR and Windows currently boots in Legacy mode, Microsoft provides the built-in MBR2GPT.exe utility for eligible installations.

The important distinction is that validation comes before conversion:

Repair common Windows errors and clear accumulated junk for a smoother, more stable PC - no reinstall needed.Free scan · no reinstallmbr2gpt /validateOnly proceed with conversion if validation succeeds, your important files are backed up, and you have followed the current Microsoft instructions for your Windows installation and execution environment. The conversion command is:
mbr2gpt /convertDo not treat these commands as a guarantee that every MBR installation can be converted. Eligibility depends on the disk and Windows layout. Microsoft’s current MBR2GPT documentation and the PC manufacturer’s instructions take priority, including any requirements about running the tool from Windows Recovery or another supported environment.
After a successful conversion, enter UEFI/BIOS and change the boot configuration from Legacy/CSM to UEFI. Make sure Windows Boot Manager remains the selected boot entry. If the computer cannot boot after the change, return to the previous firmware setting if possible and seek manufacturer support rather than repeatedly changing unrelated options.
Step 7: Enable Secure Boot
Return to UEFI/BIOS after the PC is configured for UEFI and the system disk is GPT. Secure Boot may be located under Boot, Security, or Windows OS Configuration.
- Find the operating-system or boot-mode setting and select a Windows-oriented UEFI mode if your firmware provides that choice.
- Find Secure Boot.
- Set it to Enabled.
- If the firmware offers a choice between standard and custom modes, use the manufacturer’s normal Windows setting, commonly Standard.
- Save changes and restart.
Do not clear Secure Boot keys as a routine troubleshooting step. Key-management options are model-specific and can create additional boot problems. If Secure Boot is greyed out, unavailable, or asks for an unfamiliar key configuration, first verify UEFI mode, GPT partitioning, firmware updates, and the manufacturer’s instructions.
Step 8: Verify every requirement in Windows
After Windows starts again, check all three security and boot conditions rather than assuming the firmware change worked.

- If it is available for your installation, run Activision’s Call of Duty Secure Attestation Wizard. Activision describes it as a tool that checks BIOS information and reports whether the PC meets the Black Ops 7 and Warzone requirements.
The attestation result is especially useful when Windows appears compliant but the game continues to display a security requirement message. It checks the firmware information relevant to Call of Duty rather than relying only on one Windows status screen.
If Secure Boot is missing or greyed out
Check these items in order:
- BIOS Mode must be UEFI, not Legacy.
- The Windows system disk must be GPT, not MBR.
- Legacy or CSM boot support may need to be disabled after the installation is ready for UEFI.
- The firmware may need to be updated for the specific PC or motherboard model.
- The firmware may require a Windows/UEFI operating-system mode or Standard Secure Boot mode.
- The manufacturer may document a specific factory-key step, but do not clear or replace keys unless that documentation explicitly requires it.
Secure Boot cannot normally be enabled safely by changing only one toggle when the Windows installation is still Legacy/MBR. Fix the boot mode and partition style first.

Do not use generic driver-updater software as the first fix. This problem concerns firmware, boot configuration, TPM state, and attestation; the relevant remedies are manufacturer documentation, an appropriate BIOS/UEFI update, and Activision’s verification tool.
When to use manufacturer or professional support
Contact the PC or motherboard manufacturer if you cannot identify the correct TPM setting, Secure Boot is unavailable despite UEFI/GPT configuration, a firmware update is required, or the computer no longer boots after a change. Have the exact model number and current BIOS/UEFI version ready.
If the machine cannot boot and you cannot safely reverse the change, get manufacturer or professional help rather than clearing keys, repeatedly changing boot modes, or experimenting with unrelated firmware options. A repair service is not necessary for the ordinary case, but it can be appropriate when recovery or firmware configuration is beyond your comfort level.
Windows Secure Boot certificate changes in 2026
Microsoft is updating Secure Boot certificates that originated in 2011 and are approaching expiration in 2026. This is separate from the basic steps required to turn Secure Boot on for Black Ops 7.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsWindows Security may show additional information about Secure Boot certificate-update status. Some systems may require assistance from the PC manufacturer if hardware or firmware limitations prevent an automated certificate update. If Secure Boot is already On but Windows displays a certificate-related warning, follow the manufacturer’s and Microsoft’s guidance for that warning rather than disabling Secure Boot.

Final compliance checklist
- Windows 10 version 22H2 or later, or Windows 11
tpm.mscreports a TPM ready for use- TPM specification version is 2.0
msinfo32reports BIOS Mode: UEFI- The Windows system disk uses GPT
msinfo32reports Secure Boot State: On- Windows Security shows the expected security-processor and Secure Boot information
- Activision’s Secure Attestation Wizard, if available, reports compliance
Once all of these checks pass, restart the PC one more time and launch Black Ops 7. If the game still reports noncompliance, the remaining issue is most likely a firmware version, manufacturer-specific configuration, or attestation problem rather than a missing Windows driver.
Frequently Asked Questions
Do I need to buy a TPM module for Black Ops 7?
No. Many Intel systems use Intel PTT and many AMD systems use AMD CPU fTPM, both of which provide firmware-based TPM functionality. A discrete TPM module is only one possible implementation and must be compatible with the specific motherboard.
Can I enable Secure Boot if my disk is MBR?
Not necessarily. Check the system disk first. If it is MBR and Windows boots in Legacy mode, Microsoft’s MBR2GPT utility may be able to convert it, but you must run validation first, back up important data, and follow the current Microsoft and manufacturer instructions.
Why is Secure Boot greyed out?
No. Secure Boot requires UEFI rather than Legacy/CSM boot mode, and the Windows system disk generally needs to use GPT. Switching firmware modes without converting or checking the disk can make Windows fail to boot.
What should I do if Black Ops 7 still says TPM or Secure Boot is disabled?
Run tpm.msc and confirm the TPM is ready for use and reports specification version 2.0. Then check msinfo32 for BIOS Mode: UEFI and Secure Boot State: On, verify that the system disk is GPT, restart the PC, and check for a BIOS/UEFI update from the manufacturer. If the game still reports a problem, run Activision’s Secure Attestation Wizard if available.
The Bottom Line
For Black Ops 7, enable the PC’s existing TPM 2.0 implementation—Intel PTT or AMD fTPM—then make sure Windows boots in UEFI mode from a GPT disk before enabling Secure Boot. Verify the result with tpm.msc, msinfo32, Windows Security, and Activision’s attestation tool. Do not switch Legacy to UEFI or clear Secure Boot keys without checking the manufacturer’s instructions first.
