√ How To Load Windows 11 on Unsupported PC

I nstalling Windows 11 on an unsupported PC might seem like a daunting task, especially with Microsoft’s stringent hardware requirements. However, with tools like Rufus, even older machines can run the latest OS with a few clever bypasses. In this comprehensive 2025 guide, you’ll learn exactly how to create a bootable USB using Rufus and use it to install Windows 11 on a device that does not meet TPM, Secure Boot, or RAM requirements.

What Does “Unsupported PC” Mean?

Microsoft has set specific system requirements for Windows 11, including TPM 2.0, Secure Boot, and minimum processor benchmarks. PCs not meeting these requirements are labelled “unsupported.” While these devices can still run Windows 11, you won't receive official support or updates from Microsoft.

Why Use Rufus?

Rufus is a free, lightweight utility that allows users to create bootable USB drives easily. It includes options to bypass Windows 11 installation checks, making it the perfect tool for unsupported PCs.

Step-by-Step Guide to Load Windows 11 on an Unsupported PC

Before diving into the process, make sure you have a USB drive with at least 8GB capacity, the latest Windows 11 ISO, and a backup of your files.

Download the latest version of Rufus.
Insert your USB drive and launch Rufus.
Under “Device,” select your USB.
Under “Boot Selection,” choose the Windows 11 ISO.
Set “Partition Scheme” to GPT and “File System” to NTFS.
Click “Start.” Rufus will now offer additional options.
Tick checkboxes to disable TPM, Secure Boot, and RAM checks.
Proceed and wait for the bootable USB to be created.

Using the Bootable USB to Install Windows 11

Once your USB is ready, follow these steps:

Insert the USB into the target PC.
Reboot and enter BIOS (commonly by pressing DEL or F2).
Disable Secure Boot if enabled.
Set USB as the first boot device.
Save changes and restart.
Follow on-screen prompts to install Windows 11.
