Part 2. How to Install Windows 11 25H2 on Unsupported Hardware

One of the most reliable ways to install Windows 11 version 25H2 on unsupported hardware is by creating a bootable USB using a modified Windows 11 25H2 ISO file. This method lets you skip hardware checks that usually block installation on older PCs.

Method: Create Bootable Media with Modified ISO (Rufus or DISM)

• Download the Official Windows 11 25H2 ISO. Select Windows 11 from the drop-down menu under the “Download Windows 11 Disk Image (ISO) for x64 devices” section, and click “Confirm” . Then, choose the language and download it.

  

• Next, you should download Rufus with the latest version. Launch it, and select “USB flash drive” under the “Device” section; and click “Select” choosing “Windows 11 25H2 ISO”, then click “Open”.

  

• Choose “Standard Windows 11 Installation” under the Image option, set Partition scheme to GPT, and select UEFI (non-CSM) under the target system. Enter a clear name for your bootable USB in the Volume label.

• Next steps are crucial for upgrading Windows 11 version 25H2. File system and Cluster size keep default settings. Here are the options that should be checked:

  • Quick format
  • Create extended label and icon files
  • Remove requirement for 4GB+ RAM, Secure Boot and TPM 2.0
  • Remove requirement for an online Microsoft account
  • Disable BitLocker automatic device encryption
  

  These can help you bypass Windows 11 25h2 requirements. Once the process is complete, the tool will create a bootable USB drive with the Windows 11 version 25H2 installation files, ready for use on unsupported hardware.

• After that, you just boot from the modified USB and launch setup.exe to upgrade.
