What Should I Do If Windows 11 Installation Has Failed?

Many users are faced with the problem of “Windows 11 installation has failed on your computer” when installing the system. The reason is that the computer does not fulfill the minimum system requirements for installing Windows 11.

The Minimum System Requirements for Windows 11 Are as Follows:

  • Processor: 1 gigahertz (GHz) or faster with 2 or more cores on a compatible 64-bit processor or System on a Chip (SoC)
  • RAM: 4 gigabyte (GB)
  • Storage: 64 GB or larger storage device
  • System firmware: UEFI, Secure Boot capable
  • TPM: Trusted Platform Module (TPM) version 2.0
  • Graphics card: Compatible with DirectX 12 or later with WDDM 2.0 driver
  • Display: High definition (720p) display that is greater than 9” diagonally, 8 bits per color channel
  • Internet connection and Microsoft accounts: Windows 11 Home edition requires internet connectivity and a Microsoft account to complete device setup on first use.

You may see the following installation failure prompts if the above configuration is not met:

  • This PC doesn’t meet the system requirements to run Windows 11.
  • The processor isn’t supported for Windows 11.
  • TPM2.0 is a requirement for running Windows 11.
  • PC must support Secure Boot.
  • The system disk needs to be 64GB or larger.                       

    Installation Failure Prompts

     

If all of the above requirements are met but Windows 11 installation has failed, the most likely cause is that “TPM2.0” and “Secure Boot” are not available in the BIOS. The steps below will tell you how to enable “TPM2.0” and “Secure Boot,” as well as how to install Windows 11 without using “TPM2.0” or “Secure Boot.”

Method 1: Solve Windows 11 Has Failed to Start by Enabling TPM 2.0 and Secure Boot

Part 1: Solve Windows 11 Installation Has Failed by Enabling TPM2.0

What is TPM2.0? A TPM is a computer chip that offers a system with hardware-based security functionalities. The hardware limitation is that it requires CPU and BIOS/UEFI firmware support. The CPU used to install Windows 11 must fall within Microsoft’s permitted range. The following are the Intel CPU and AMD CPU support ranges given by Microsoft:

  • 8th Generation Intel Core Processors and Newer Products
  • AMD Ryzen Processor
  • Ryzen 3000 Series and Newer Products

The PC health check will also show “can’t run Windows 11” even if earlier models support and enable TPM 2.0. The following methods can be used to determine whether the system has a TPM chip and whether it is enabled.

How to Check the TPM2.0 of our Computer

1. Press “Win” and “R” together to open the interface, then type “tpm.msc” and click “OK”.

Open The Interface

2. The TPM management window on the local computer will open. If the “Status” is “The TPM is ready for use”, it means that the TPM is enabled. You can verify the TPM version for the TPM manufacturer information in the lower right corner.

Tpm Status

3. If the TPM version is compatible but disabled (the computer will prompt “Compatible TPM can’t be found”), then turn it on in the BIOS.

Compatible Tpm Can’t Be Found

How to Enable TPM2.0 in BIOS Settings

1. To quickly access the Windows Advanced Options menu, we will press the Shift key while clicking Restart to enter the boot page, and select “Troubleshoot”.

Troubleshoot

2. Select “Advanced Options”

Advanced Options

3. Select “UEFI Firmware Settings” to enter the BIOS settings.

4. The name in the BIOS setting will be different, because the motherboard of the computer is different. TPM or PTT have the same function, just open it directly. For some computers, the TPM will be located in the advanced options and the name is Trusted Platform Module. Follow the steps in the diagram to turn on TPM.

Part 2: Solve Windows 11 Installation Has Failed by Enabling Secure Boot

What is Secure Boot, and how does it work? It’s a security standard that ensures PCs are only booted with software trusted by OEM (Original Equipment Manufacturer. It prevents malware from launching when you boot your computer. Only drivers with Microsoft certifications will be loaded if this option is selected.

Windows 11 requires Secure Boot to be enabled on the system to run the latest version. Fortunately, Secure Boot has extensive system support. Your PC may support it, but it just isn't enabled. Booting into the BIOS and checking whether the BIOS security settings can enable Secure Boot on your system is the quickest approach to validate Secure Boot support on your PC.

How to Enable Secure Boot in BIOS settings?

1. Restart and press Del to enter the BIOS system (keys are different depending on the computer host), click the “Boot” bar, and select “Secure Boot”.

Select Secure Boot

2. We can see that Secure Boot is disabled, and we select “Key Management”.

3. Select “Install default Secure Boot keys” to enable secure boot.

4. Returning to the previous column, we can see that Secure Boot has been enabled.

Method 2: Solve Windows 11 Has Failed to Start by Bypassing the “Secure Boot” and “TPM 2.0” Requirements

Installing Windows 11 has the problem that it requires “Secure Boot” and “TPM 2.0” to be enabled on the computer, if you are in “UEFI BIOS mode”, enabling these two options is a very simple process. However, in “Legacy BIOS mode”, this is not possible at all. So, we can bypass the Secure Boot and TPM 2.0 check during Windows 11 installation by modifying some registry keys values on the Windows PC.

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

 

Regedit

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

System Setup

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

Abconfig

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

Create New Dword Value

5. Name them “BypassTPMCheck” and “BypassSecureBootCheck” respectively.

Bypass Tpm Secure Boot

6. Then double-click the two “DWORD” and edit their “Value Data” field to “1” respectively.

Value Data

7. When finished, close the registry editor window and restart the computer to make the new registry key take effect. Finally, try to run the Windows 11 setup by installing the Windows 11 ISO on the Windows PC. It will bypass TPM 2.0 and Secure Boot check and allow you to install Windows 11.
