The full error message reads:

This PC can’t run Windows 11—While this PC doesn’t meet the system requirements to run Windows 11, you’ll keep getting Windows 10 updates.

You may also see the following error:

  • This PC must support TMP 1.2/2.0.
  • This PC must support Secure Boot.

If you encounter a similar error and want to know if you need to upgrade to new hardware to install Windows 11, this is the article you need.

What Are the System Requirements to Install Windows 11?

Interestingly, the official system requirements for Windows 11 are not the strictest, and most modern systems should support this immediately. However, Windows 10 has some upgrades.

The following are the system requirements for installing and running Windows 11:

  • 1GHz 64-bit processor
  • 4GB of RAM
  • 64 GB of storage space
  • System firmware that supports UEFI, Secure Boot capable
  • Trusted Platform Module (TPM) 1.2/2.0.

If you now meet the hardware specifications and the PC can still run Windows 11 errors when using the PC health check application, you can solve this problem by adjusting some settings in the BIOS / UEFI settings.

This error can also occur when installing Windows 11 using a bootable drive or installation files from the installed ISO.

What Is UEFI Boot Mode?

UEFI (Unified Extensible Firmware Interface) is an alternative to BIOS (Basic Input Output System) boot method. For traditional boot, the system uses the BIOS firmware to boot.

Generally, it is recommended to install Windows in the newer UEFI mode because this mode has more security features, such as secure boot, compared to the traditional BIOS mode.

What Causes the “PC Can’t Run Windows 11 Error?”

This error occurs when you run the PC health check application to check whether your PC supports Windows 11, or when you try to install Windows 11 from a bootable flash drive or use the installation file from the installed ISO.

For Windows 11 to be compatible with your computer, it must support UEFI and secure boot, and TPM 1.2 or 2.0 must be enabled.

Since Windows 11 requires a system compatible with UEFI secure boot, if you install Windows 10 through the traditional boot mode, the installer cannot recognize the required functions.

This solves the error that this PC cannot install Windows 11 because the system requirements are not met. Even if your PC supports Secure Boot and TMP 2.0, you may still need to enable them to fix errors manually.

If you are using the traditional boot mode, you must set the boot mode to UEFI in the BIOS settings to activate the secure boot function (it may also activate TMP 1.2 / 2.0).

How to Fix the “This PC Can’t Run Windows 11 Error?”

To fix this error, you should set the boot mode to UEFI and enable secure boot, and then make sure that TPM 1.2 / 2.0 is enabled on your computer. Note that the label name may vary from manufacturer to manufacturer, but the description should be roughly transferred to the hardware.

1. Enable Secure Boot in Windows 10

Follow these steps to enable Secure Boot compatibility in Windows 10.

  1. Close all the open Windows and save your work. Then shut down your PC.
  2. Restart your system and start pressing F2 to enter BIOS setup. Different laptop and PC manufacturers may use other function keys such as F12, F10, F8, or Esc key to enter BIOS.
  3. In the BIOS setup utility, use the arrow keys to open the Boot tab. Highlight Boot Mode and check if it is set to Legacy.
  4. To change the Boot Mode, press Enter while the Boot Mode is highlighted.
  5. Choose UEFI from the options. Use the Up and Down arrow keys to select UEFI, and hit Enter to select the option.
  6. Next, open the Security tab.
  7. Highlight the Secure Boot option using the arrow keys and hit Enter.
  8. Choose Enabled to enable Secure Boot on your PC.

After activating secure boot and UEFI in boot mode, make sure that TPM 1.2 / 2.0 is also activated for your PC. So do not close the BIOS setup menu.

2. Enable TMP 1.2/2.0 to fix the “This PC Can’t Install Windows 11 Error”

TMP 1.2/2.0 feature is accessible from the BIOS setup as well. Here’s how to do it.

  1. In BIOS/UEFI, open the Security tab.
  2. Scroll down and highlight the Trusted Platform Technology option, and hit Enter. On Intel laptops, you may see the Intel Platform Trust Technology option instead.
  3. Choose Enabled and press Enter to apply your selection.
  4. Save the changes and exit.

That’s it. You have successfully activated Safe Boot Compatibility and TMP 2.0 under Windows 10. Restart your PC, run the PC Health Check Tool, or install Windows 11 to see if the error is resolved.

No Boot Device Found Error After Changing Boot Mode from Legacy to UEFI

When changing the boot mode of an existing Windows 10 installation from an older version to UEFI, a “boot device not found” error may appear. However, there is nothing to worry about.

By changing the boot mode from UEFI back to traditional in the BIOS settings, you can easily boot to an existing Windows 10 installation.

Next, use the MBR2GTP tool to convert your installation drive/disk from Master Boot Record (MBR) to GUID Partition Table (GPT) without changing or deleting any data on the disk. More information about using MBR2GRP can be found here.

After converting the drive, you can change the boot mode from Legacy to UEFI without the No Boot Device Found error.

Or, if you plan to install Windows 11 cleanly, make sure to install Windows 11 (or Windows 10) in UEFI mode to avoid problems in the future.

If the bootable drive does not appear in the boot manager after enabling secure boot, make sure to format it with the UEFI system in Rufus. If not, please create a bootable drive again and set the target system to UEFI (CMS).

Now You Know How to Install Windows 11 Without Error

Windows computers with old BIOS firmware enabled cannot install Windows 11. Fortunately, you can easily fix the error by adjusting the BIOS setup utility to enable UEFI firmware mode to enable secure boot and TPM 2.0.
