How to create a Windows 11 ISO for installation on computers without UEFI, Secure Boot and TPM 2.0

In this post, friends, we will look at how to create an ISO image of Windows 11 for installation on computers without TPM 2.0, Secure Boot and UEFI. As you know, Microsoft, having presented the new Windows 11 in June 2021 with a light, effective, stylish interface and a lot of interesting functionality, at the same time broke off most of the user audience with a statement about the most stringent system requirements for the operating system.

To which computers will be able to correspond, released not earlier than 2017. During the installation of Windows 11, computers are checked for the presence and activity of three components – UEFI, Secure Boot and TPM 2.0. And if they are absent or inactive, the system is not installed. Fortunately, this check can be bypassed. Let’s, friends, create such an installation ISO for Windows 11 so that during the installation process there is no need to check these three components.

We will create such a Windows 11 installation ISO so that when the operating system is installed, it is not checked for the presence and activity of UEFI, Secure Boot and TPM 2.0, we will replace the installation image files of this system with files from the Windows 10 installation image. We will take the Windows 10 ISO image. and replace the system image file install.esd (install.wim) in it with the same one, but belonging to Windows 11. But first, a few important recommendations:

  • If you need a Windows 11 installation ISO to install on a virtual machine, there is no need to manipulate the image. During the installation of Windows 11 in a hypervisor environment, no system requirements checks are performed;
  • If you need a Windows 11 installation ISO for writing to a USB flash drive, you do not need to edit it, you can replace the install.esd file directly on the bootable USB flash drive. This process is described in detail in the article “How to create a bootable USB flash drive for Windows 11”, in particular, in the paragraph regarding the creation of a bootable USB flash drive for incompatible computers;
  • You may not bother with editing the Windows 11 installation image at all, if you master the method of installing the operating system that is suitable for yourself from among the alternative to the official method. Like Windows 10, Windows 11 will be regularly updated, and with each new installation you will need a fresh distribution – a fresh build of the system and with all the updates. And each time you need to rebuild the Windows 11 installation image. Using the alternative methods of installing Windows 11, you only need a fresh system image. For details on these methods, see the article “How to install Windows 11 without TPM 2.0, Secure Boot and UEFI”.

Well, if you fundamentally need a Windows 11 installation ISO for computers incompatible with this system, well, let’s start creating it.

 

↑ Download ISO Windows 10 and 11

 

We need installation images for Windows 10 and 11. Download:

  • Windows 10 installation ISO;
  • Windows 11 installation ISO.

 

↑ Image editing

 

Double-click on the Windows 10 ISO to connect it to be displayed in Explorer.

Copy the entire contents of the connected ISO.

Create a folder somewhere on the disk with any name and paste the copied content there. This will be the folder for the image being edited. 

In the created folder, go to the “sources” folder, display the data in a table, sort by size, look for the install.esd or install.wim file. We delete it.

Now, by double-clicking on the Windows 11 ISO, we connect it to display it in Explorer.

In the connected ISO, go to the “sources” folder, there we also display the data in a table, sort by size, look for the install.esd file. We copy it.

And we insert it in the folder of the edited image, respectively, also in the “sources” folder.

 

↑ Packaging in ISO

We have prepared the Windows 11 installation image files, now let’s pack it all into an ISO image. Downloading the free Dism ++ program. It’s portable, just run it. Go to its “Advanced” section, click “Create ISO”.

We fill in the necessary columns:

  • 1 – path to the folder of the edited image;
  • 2 – path and name of the Windows 11 installation image being created;
  • 3 – the label of the image being created.

We are waiting for the completion of the ISO creation process, the progress of the operation will be displayed in the Dism ++ window.

And we catch the image of the Windows 11 installation at the path we specified.

That’s it – we created an ISO image of Windows 11 for installation on computers without UEFI, Secure Boot and TPM 2.0.
