How to Fix Call of Duty "Failed Attestation Status"
Complexity: Intermediate | Time: 15 min
If you receive a "Failed Attestation Status" error when launching a ranked playlist in Call of Duty®, your PC is not meeting the security requirements required by the Ricochet Anti-Cheat system.
Recent updates to Microsoft's Secure Boot certificates mean that some older systems require additional configuration before Call of Duty can verify your hardware.
This issue most commonly affects systems using:
• Intel 11th Generation processors and older
• AMD Ryzen 5000 Series processors and older
In many cases, updating your BIOS and refreshing your Secure Boot keys will resolve the issue.
Why Am I Receiving This Error?
You may see a Failed Attestation Status error if:
• Your BIOS is out of date
• Secure Boot is disabled
• TPM 2.0 is disabled
• Your Secure Boot certificates are outdated
• Windows is installed in Legacy (CSM) mode instead of UEFI
• Your system drive uses the older MBR partition format instead of GPT
Before You Begin
Important: If BitLocker is enabled on your Windows drive, back up your BitLocker Recovery Key before making any BIOS changes. Updating your BIOS or changing Secure Boot settings may trigger BitLocker recovery on your next boot.
Recommended Troubleshooting Order
1. Update Your Motherboard BIOS
Installing the latest BIOS ensures your motherboard contains Microsoft's latest Secure Boot certificates and firmware fixes. Check out our guides to help you get started: BIOS Main Update Page and follow your motherboard manufacturer's BIOS update instructions.
2. Reset Secure Boot Keys
After updating your BIOS, reset the Secure Boot factory keys.
This refreshes the digital certificates used by Microsoft and allows Ricochet to verify your system correctly.
3. Confirm TPM 2.0 Is Enabled
Ensure your motherboard security processor is enabled.
Depending on your platform this will be:
• Intel PTT
• AMD fTPM
4. Confirm Secure Boot Is Enabled
Secure Boot must be enabled after resetting the factory keys.
5. Confirm Windows Is Using UEFI Boot Mode
Legacy (CSM) boot is not supported by Ricochet. If your motherboard is using CSM, change it to UEFI mode.
6. Check Your Windows Drive Format
Secure Boot requires Windows to be installed on a GPT partition.
If your system drive is still using MBR, you'll need to convert it to GPT or perform a clean Windows installation.
7. Run the Call of Duty Attestation Wizard
Once you've completed the steps above, download and run the official Call of Duty Attestation Wizard.
The tool will scan your system and identify any remaining issues preventing compliance.
Understanding Common Attestation Errors
If the Attestation Wizard reports any issues, the following explanations may help.
Authorization Key Failed
The wizard does not have permission to access your TPM.
Run the wizard as Administrator, then generate the authorization key when prompted.
TPM 2.0 Not Enabled
Your motherboard's Trusted Platform Module is disabled.
Enable Intel PTT or AMD fTPM within the BIOS.
Secure Boot Not Enabled
Secure Boot is currently disabled.
Enable Secure Boot within your BIOS after restoring the default Secure Boot keys.
BIOS Boot Mode Not Set to UEFI
Windows is currently booting using Legacy (CSM) mode.
Disable CSM and configure your motherboard to boot using UEFI.
Boot Partition Not Set to GPT
Your Windows installation is using the older MBR partition style.
Microsoft recommends GPT for Secure Boot compatibility.
While Windows includes an MBR-to-GPT conversion tool, we recommend performing a clean Windows installation whenever possible to avoid potential boot issues.
TCG Event Log Failed
Windows is missing required security event logs.
Install all available Windows Updates, restart your PC, and run the scan again.
BIOS Firmware Update Required
Your motherboard firmware is too old to support the latest Secure Boot certificates.
Update your BIOS using the latest stable version available from your motherboard manufacturer.
Important Notes
• Do not interrupt a BIOS update once it has started.
• Always use the latest stable BIOS version unless instructed otherwise.
• Updating your BIOS does not normally erase your files, but incorrect settings may prevent Windows from booting until corrected.
• BIOS menus differ between ASUS, MSI, GIGABYTE, and ASRock motherboards.
