Call of Duty: Modern War 4 refuses to launch its online modes unless the system’s Secure Boot and TPM 2.0 are active.
Why the Anti‑Cheat Needs Secure Boot and TPM 2.0
The RICOCHET Anti‑Cheat engine that underpins Modern War 4 relies on two hardware‑level protections: Secure Boot and the Trusted Platform Module (TPM). Secure Boot blocks unverified software from loading at startup, while TPM 2.0 provides a tamper‑resistant key store for the game. Together, they keep the game environment free of malicious code that could compromise fair play.
Check Your Current Settings Before Making Changes
Verify Secure Boot Status
- Press Windows + R and run
msinfo32. - Locate Secure Boot State in the System Summary.
- If it reads On, you’re set; otherwise, proceed to BIOS to enable it.
Confirm TPM 2.0 Readiness
- Launch Run, type
tpm.msc, and press Enter. - In the TPM Management console, check the Status field.
- When it says The TPM is ready to use, TPM 2.0 is active; “Not ready to use” indicates it needs to be switched on.
Enabling Secure Boot in the BIOS
Secure Boot can be toggled only from the motherboard firmware. Restart your PC and enter the BIOS (often by pressing Del, F2, or Esc during boot). Find the Secure Boot setting—usually under Boot or Security—and set it to Enabled. Save and exit.
Activating TPM 2.0
Confirm the System Drive Uses GPT
TPM 2.0 can be enabled only on GPT‑formatted drives. To check:
- Right‑click the Start button and open Disk Management.
- Select C:\ (or the system partition).
- Right‑click, choose Properties, then the Volumes tab.
- Verify that Partition style lists GPT; MBR will prevent TPM activation.
Enable TPM in BIOS
After confirming GPT, restart and revisit the BIOS. Look for a setting labeled Intel PTT or AMD fTPM under the Advanced or Security section. Select Enabled, save, and reboot. The TPM console should now report the device as ready.
What Happens If You Skip the Setup
Without both Secure Boot and TPM 2.0 active, Modern War 4’s client will reject the connection to the online servers, and any beta reward claims will fail. This restriction mirrors the approach taken with Black Ops 7 during its beta period.
By following these steps, you’ll satisfy the game’s anti‑cheat prerequisites and unlock full multiplayer access. If you hit any roadblocks, review the BIOS steps or consult your motherboard’s manual for model‑specific instructions.
