How to Fix the “This pc can’t run Windows 11” Error


This pc can’t run Windows 11 problem may result from two crucial security settings being disabled if you have attempted downloading Windows 11 or employing the Microsoft PC Health Check app after getting that warning. They are known as Secure Boot with TPM 2.0. These two options are now necessary for Windows 11-powered machines.

Despite this, you may still set up Windows 11 on your device. This article will provide you several ways to fix this pc can’t run windows 11 and enable Windows 11 on your computer.

Several Kinds of This PC Cannot Run Windows 11 

The error notice that reads “ this pc can’t run Windows 11” frequently includes the cause of the malfunction. The following are some potential causes you could observe the problem with the interface:

  • TPM 2.0 is necessary to operate Windows 11.
  • A system disk of 64GB or more is required.
  • Windows 11 does not support the CPU.
  • Secure Boot must work on the computer.
  • PC must be TPM 2.0 compatible.
  • The Basic Hardware Parameters for Windows 11 Are Not Satisfied by Your PC

Knowing the cause will make it simple for you to fix the problem. Your machine needs to run UEFI using Secure Boot and have TPM 1.2 or 2.0 enabled for the latest version of Windows 11 to work with it.

If you downloaded Windows 10 using the conventional boot mode, Windows 11 would not recognize the necessary functionality since it needs a UEFI Secure Boot capable PC. Due to inadequate system demands, this can result in an error message and you then need to fix this pc can’t run windows 11.

Notably, the manufacturer’s Windows 11 system specifications are relatively inexpensive, and the majority of contemporary PCs ought to be able to run it right out of the box. There are some improvements from Windows 10, though.

The systems needed to set up and execute Windows 11 are as follows:

  • 1GHz, 64-bit
  • 4GB of RAM,
  • 64 GB of space
  • Firmware for the system – UEFI and Secure Boot compatible
  • TPM 1.2/2.0: Trusted Platform Module.

Suppose you have a computer that meets the requirements for running Windows 11 but still receives this issue while installing the Personal Computer Health Checkup program. In that case, you may resolve it by adjusting your BIOS/UEFI configuration.

If you switch the Boot Type for a previous Windows 10 setup from Legacy to UEFI, you can get the No Boot Item Found issue. Still, by switching the Boot Mode between UEFI to Legacy once more in the BIOS settings, you may quickly boot into your current version of Windows 10.

Then, without changing or erasing any of the data stored on the disk, employ the MBR2GTP utility to switch your drive/disk configuration from the Master Boot Record (MBR) to the GUID Partition Table (GPT). You may read more about MBR2GRP use here.

After converting the disk, you may switch from Legacy to UEFI boot modes without seeing the No Boot Device Available warning. To avoid future problems, configure Windows 11 (or even Windows 10) in the UEFI version if you want to perform a fresh installation of the operating system.

After activating Secure Boot:

  1. Check if the bootable device appears within the Boot Manager.
  2. If not, make sure Rufus has prepared it using the UEFI standard.
  3. If not, make another bootable disc with UEFI (CMS) as the target system.


Windows machines with older BIOS firmware will be unable to launch Windows 11 on them. However, you can quickly fix this pc can’t run windows 11 issue by making a few changes to your BIOS setup software to activate UEFI bios mode to turn on Secure Boot with TPM 2.0.
