Windows 11 Installation Error: "This PC Can't Run Windows 11" – TPM 2.0 and Secure Boot Issue

Issue:

While trying to upgrade or install Windows 11, you receive the following message:

“This PC can’t run Windows 11. The PC must support TPM 2.0 and Secure Boot.”

Explanation:

Windows 11 has new system requirements, including Trusted Platform Module (TPM) version 2.0 and Secure Boot enabled in BIOS/UEFI. If your hardware supports them but they are turned off, the installation will fail.

Solution

Restart your PC and enter BIOS/UEFI:

Usually by pressing DEL, F2, or F10 right after powering on your PC (check your PC/laptop brand for exact key).

Enable TPM:

Go to the Security or Advanced tab.

Look for TPM, PTT (on Intel systems), or fTPM (on AMD systems).

Enable it.

Enable Secure Boot:

Go to the Boot tab.

Find the Secure Boot option and enable it.

Make sure Boot Mode is set to UEFI (not Legacy/CSM).

Save Changes & Exit BIOS:

Press F10 or use the Save & Exit option.

Retry the Windows 11 Installation:

Boot from the USB or use the upgrade tool again.

💡 Tip: Use Microsoft’s PC Health Check Tool to verify compatibility before installing.
