Download and clean install the latest preview of Windows 11

Spread the love

Windows 11 is the next major release that Microsoft plans to start rolling out to compatible and new devices before the end of the year. As part of the development process, the company is now offering the ISO file through the Windows Insider Program, which you can use for a clean installation or in-place upgrade.

A clean installation defines the process of erasing the hard drive to start fresh with a copy of Windows 11. Usually, you would use this method to resolve system problems and improve performance and battery life. However, since the OS is not officially available, you can use the ISO file to install Windows 11 on a spare or virtual machine to try the out-of-box experience (OOBE) and get hands-on the new features and design changes to provide feedback to shape the future of Windows.

If you are already a tester, you do not need to reinstall anything since the latest release will download and install through Windows Update automatically. Also, if you will be installing a clean copy of Windows 11 on a new computer or virtual machine, you will need a (Windows 10) product key to activate the setup. Unless, of course, the device previously had a Windows 10 installation properly activated.

In this Windows 11 guide, we will walk you through the steps to download and do a clean installation of the latest preview on a (non-primary) computer.

Windows 11 prerequisites

Windows 11 has some new requirements that you want to check to ensure the new OS will install without problems.

    Quick note: The RAM has to be larger than 4GB, and the processor must be an Intel’s 8th Gen or newer or an AMD Zen 2 or newer. You can find more information on the processor compatibility in this guide. Also, the system type must be 64-bit, since the OS no longer comes in 32-bit.

  6. Confirm the hard drive is larger than 64GB.

You can also check your laptop or desktop hardware specification on the manufacturer’s support website.

In addition, you will also need to make sure that your device has a Trusted Platform Module (TPM) version 2.0, and that it’s enabled. You can complete this task with these instructions.

Furthermore, Windows 11 also requires Secure Boot to be enabled. You can use this guide to check the feature state and the steps to turn it on as necessary.

Alternatively, you can use a third-party tool known as WhyNotWin11, which can precisely tell you if your computer is compatible.

Change computer boot order

In addition, to check the hardware compatibility, you also need to make sure the laptop or desktop can start from a USB flash drive.

UEFI settings from boot

To change the boot order of your computer, use these steps:

  1. Start the computer.
  2. As soon as the computer starts booting up, press one of the function keys (F1, F2, F3, F10, or F12), Esc, or the Delete key.
  3. While in the motherboard firmware settings, open the Boot page.
  4. Set the boot order to start from the USB media with the Windows 10 installation files.

  11. Select the partition with the current installation (usually “Drive 0”), and click the Delete button.

    Quick tip: If “Drive 0” has multiple partitions, you have to select and delete each partition to allow the setup to use the entire drive for the new installation.

If the device has an empty hard drive, select it and click the Next button.

  12. Click the Yes button.
  13. Select the empty drive (Drive 0 Unallocated Space).
