How to fix or bypass "This PC Can't run Windows 11" from bootable USB disk

Copper Contributor

Hi community folks,

 

I am new to Windows and want to test out Windows 11 on my spare PC before making a real switch to it.   I made a Windows 11 bootable USB and the installation wizard loads up successfully at the beginning. However, the error screen pops up saying This PC Can't Windows 11. And there is no way to proceed with the installation as this PC does not meet the minimum system requirements to install this version of Windows 11.

 

The Windows 11 ISO is downloaded from Microsoft. And it is the latest version 23H2. My PC specs:

 

  • Intel i5-7400
  • 8 GB RAM
  • 256 SSD

 

Is there any way to fix or bypass This PC can't Windows 11 error so we can use Windows 11 on my unsupported PC?

 

Thanks

Windows 11 requires at least 8 Gen i5 CPU for installation according to Microsoft official statement:

Your CPU is i5 7 Gen. This is the reason why Windows 11 can't run on your PC. Do you have any plan to upgrade the PC?

Based on the information you've given, it seems your computer is not compatible with Windows 11. The error message "This PC can't run Windows 11" generally indicates that the hardware specs of your computer fails to meet one or more of the essential criteria for Windows 11, such as TPM 2.0, Secure Boot, or the necessary CPU support. A good first step is to verify the settings in your BIOS, making sure Secure Boot is on and TPM 2.0 is both present and active.

 

En effective workaround to fix "This PC can't run Windows 11" error is to modify the registry and remove the restrictions for Windows 11. This can be done by enabling the "Bypass Windows 11's TPM, Secure Boot and CPU" option in WinBootMate. Below is the tutorial and screenshot:

Also, ensure that all external drives and peripherals are disconnected. Proceed to update or reset the BIOS or UEFI firmware to the latest version. During this process, make sure to enable UEFI (if available), disable CSM or Legacy BIOS, and set Windows Boot Manager as the primary boot option. It may be necessary to temporarily turn off Secure Boot and Fast Boot until the installation is complete.  Remember to save these changes before exiting.

 

If these steps don't resolve the issue, consider transferring the hard drive to a different PC for the installation, ensuring it's the only drive connected. Windows 11 is notably flexible when it comes to adapting to new hardware and doesn't typically require an adaptive restore. If the system boots, it will automatically replace all necessary drivers, which may require multiple restarts. Another option is to apply a system image of the same version to the existing SSD or hard drive.

Windows 11 has specific hardware requirements, including a compatible processor, a certain amount of RAM, and a supported motherboard. If your spare PC does not meet these requirements, you will not be able to install Windows 11 on it.

However, if you still want to test Windows 11 on your spare PC, there are a few alternative options you can consider:

Modify the Windows 11 ISO: You can modify the Windows 11 ISO file by editing the configuration files and removing the minimum hardware requirement checks. This method is not recommended unless you have a good understanding of how to modify the ISO file, as it can result in damage to your system.

Use a third-party patch: There are several third-party patches available that claim to remove the minimum system requirements check and allow you to install Windows 11 on unsupported hardware. However, these patches come with potential risks such as malware and instability issues, so be sure to download from a trusted source and take a backup of your system before installing.
If you are receiving the "This PC Can't run Windows 11" error message when trying to install Windows 11 from a bootable USB disk, it means that your computer does not meet the minimum system requirements to run the operating system.

Here are some steps you can take to try to fix or bypass this error:

Make sure your computer meets the minimum system requirements for Windows 11. Check the Microsoft website for the system requirements and compare them to your computer specifications.

Check for BIOS updates. Some older computer models may need a BIOS update to support the new TPM 2.0 and secure boot technologies that are required by Windows 11.

Enable TPM and Secure Boot in your computer's BIOS settings. These security features are required for Windows 11 installation. Look for these settings in your computer's BIOS and make sure they are enabled.

Try modifying the Installation files. Some experienced Windows users have reported success bypassing the minimum system requirements by modifying specific installation files. However, this requires advanced technical knowledge, and it is not recommended as it can lead to system instability or other issues.

If none of these steps work, you may need to upgrade your computer's hardware to meet the minimum system requirements to run Windows 11.

"This PC Can't run Windows 11" error message will show up when Windows 11 identifies a computer that does not meet its basic system specifications. This statement doesn't imply the computer is completely incapable of Windows 11. Yet, the absence of even a single necessary element can prompt this alert and stop the installation of Windows 11. Notably, unsupported CPU in your case as well TPM and secure boot are the primary culprits behind this error. These are security protocols that can be activated either through Windows settings or your BIOS (UEFI) setup. 

One of the most effective tricks to fix "This PC can't run Windows 11" is to edit the registry during Windows 11 installation. Open Registry editor and add a new entry (AllowUpgradesWithUnsupportedTPMOrCPU) and set the value to 1.
Keep in mind, modifying your registry comes with risks, as the Windows registry holds essential low-level configurations that could lead to problems if changed improperly. Therefore, it's advisable to back up your registry or establish a restore point prior to proceeding with this approach. This allows you to revert any changes made by mistake.

 

@Lurtoonans Thank you for your informative post. One question I have is where in the registry do you add the new entry?  Thank you
