How to Install Windows 11 on Unsupported hardware

Download the latest version of Rufus from here. You can pick the portable version if you want a one-click experience.
Head over to the official website for Windows 11 ISO download.
Under the Download Windows 11 Disk Image (ISO) section, click on Select Download, and select Windows 11. Click on the blue Download button.
This will prompt you to select the language for your ISO. Under the Select the product language section, click on Choose one. Pick your preferred language from the dropdown, and click on Confirm. The download will begin.

Once the ISO download is complete, connect the USB driv to your computer, and start Rufus.

Rufus will automatically detect the USB drive, but in case it doesn’t, or if you see a different drive selected, click on the dropdown menu under the Device label, and select your USB drive.

Click on the SELECT button under the Boot Selection label, to the right. Navigate to the downloaded Windows 11 ISO file, and select it. Rufus will populate the rest of the settings, which you have to change according to your system of choice.

Under the Image Options label, select Extended Windows 11 in installation (no TPM / no Secure Boot). This setting exists to ensure you can install Windows 11 without TPM checking halting the process.

Depending upon your BIOS Mode as determined earlier, under the Partition Scheme label, select MBR, if you have a BIOS system or GPT, if if you have a UEFI system. You should see the Target System label reflect your BIOS Mode as you switch the Partition Scheme.

If you have a rather old 64-bit system you’re attempting this on, check the Add fixes for old BIOSes option. Your final Rufus screen should look something like this.

Click on Start to create the bootable USB. It will take some time to write the files to the USB drive. You will see a confirmation when the process is complete.
