Why Windows 11 Installation Has Failed?

After the launch of Windows 11, many Windows users want to upgrade to Windows 11 to experience it. However, some users have received the following error message "This PC can’t run Windows 11" or "This PC doesn't currently meet Windows 11 system requirements" when trying to install Windows 11. Mostly, your Windows 11 installation failed because your computer does not support TPM 2.0 and Secure Boot.

So, what should you do if you don't have TPM 2.0 and Secure Boot? In this article, we will show you how to clean install Windows 11 without TPM 2.0 and Secure Boot.

What are TPM and Secure Boot?

TPM (Trusted Platform Module) is a security module that is normally soldered as a chip onto the motherboard. It functions as a cryptographic processor, creating hashes and storing cryptographic keys, biometric data, user data, and other data using a hardware-based approach. 

Secure Boot is one feature of the latest UEFI. The feature defines an entirely new interface between the operating system and firmware/BIOS. When enabled and fully configured, Secure Boot helps a computer resist attacks and infection from malware.

How to Clean Install Windows 11 without TPM and Secure Boot

According to the minimum requirements of installing Windows 11, the computer needs to support TPM and Secure Boot. If you are in UEFI BIOS mode, you can easily enable the two options. But if you are in Legacy Windows 11 mode, there is no way to do that. So we need to modify some registry key values on the Windows PC to clean install Windows 11 without Secure Boot and TPM 2.0. You can follow the tutorial below to bypass TPM and Secure Boot checks when Windows 11 no tpm available.

Step 1. Press win+R to open the Run interface, and type regedit to open the registry.


Step 2. In the Registry Editor window, navigate to the following directory.

Step 3. Right-click on the blank space on the right, select New, and then select Key. A new registry key will be added on the left side of the editor. Please be sure to name it LabConfig.


Step 4. Under the LabConfig key, right-click the blank space to create two DWORD (32-bit) Value options to create new DWORD value.

Step 5. Name them BypassTPMCheck and BypassSecureBootCheck respectively.
