Create Windows 11 ISO Using Rufus for Older Systems
Rufus creates a bootable USB drive that bypasses Microsoft hardware checks like TPM 2.0 and Secure Boot so you can install Windows 11 on older, unsupported PCs. This free tool modifies the standard installation files during the setup process to let you bypass official system requirements.
To use this method, connect a blank USB drive with at least 8GB of space and download the official Windows 11 ISO file from Microsoft. You still need a valid product key to activate Windows once the installation finishes on your computer.
Use Rufus to create a bootable USB drive that bypasses Windows 11 hardware checks. Download the Windows 11 ISO, then open Rufus, select your USB drive, choose the ISO, and select the “Extended Windows 11 Installation” option before clicking START.
How to use 🪟 Windows 11 on older PCs
You can use Windows 11 on older PCs by using a Windows 11 ISO Rufus tool to bypass strict system checks. This lets you install the operating system on unsupported hardware by removing processor, RAM, and TPM requirements during the bootable drive creation process.
After downloading the official Windows 11 ISO, head to the link below to download the Rufus (beta) version.

Future versions might differ.

Once downloaded, open Rufus and insert the USB drive you want to use. Next, browse for and select the official Windows 11 ISO file.
Then, adjust the highlighted options in the image below to match your setup.
- Image option: Extended Windows 11 Installation (no TPM/no Secure Boot/8GB - RAM)
- Partition scheme: GPT
- Target system: UEFI (non-CSM)

With the settings configured, click START to begin creating the ISO image for unsupported PCs.
Allow the creation process to complete fully. Afterward, eject the USB drive and use it to install Windows 11.

That completes the process.

Was reading somewhere that if you don’t have the UEFI and Legacy only then on the Partition Scheme use the MBR instead, I tried it with the GPT and it didn’t work for me, so now I’m redoing it and using the MBR scheme and hopefully it will work this time, and it takes a long time for Rufus to complete the image on the USB, on my system anyhow, Dell workstation T3500 with an Intel Xeon 6580 I recently installed.
