Perform clean install of Windows 11 (six ways)

UPDATED 6/27/2023: On Windows 11, a clean installation refers to erasing the hard drive and applying a fresh copy of the operating system without custom settings, drivers, apps, or files. Typically, this is the recommended approach to upgrade to the latest version of Windows 11 on compatible hardware to prevent installation issues and fix existing problems.

For instance, if the computer has had the same setup for a long time, a clean install of Windows 11 can help resolve performance issues, problems shutting down, booting up, memory, and apps. Also, this installation method is the best way to upgrade from an older version (such as Windows 7 or 8.1). In addition, you can use this option to delete annoying bloatware preloaded with the default setup.

Microsoft supports multiple ways to clean install Windows 11, including using a USB flash drive to set up the operating system on an SSD (Solid-State Drive). Using the “Reset this PC” feature also possible to quickly wipe out the hard drive and reinstall the system without additional tools. Or, if the device does not start, you can use the Advanced startup options or mount the ISO file to File Explorer to commence a clean install.

In this guide, you will learn six different ways to perform a clean installation of Windows 11 22H2 or version 21H2 on your computer. However, before proceeding with these instructions, do these things before installing.

Important: This process will delete everything on your device. It’s recommended to make a full backup of your computer before proceeding. You’ve been warned. Also, these instructions are meant to help you install Windows 11 when it’s officially available, not before.

Clean install Windows 11 from USB

Using a USB flash drive is the most straightforward method to clean install Windows 11. You can create a bootable media using the Media Creation Tool, Command Prompt, Rufus, or any other third-party tool. (See also this video tutorial with the installation process from USB at the Pureinfotech YouTube channel.)

If you choose this method, you must also ensure the device can start from USB, which means you must change the BIOS or UEFI settings. The only caveat is that since most computers have different settings, you must check your manufacturer support website for more specific details.

To perform a clean install of Windows 11 from USB, use these steps:

Start the PC with the Windows 11 USB flash drive.
Press any key to continue.
Click the Next button.
Click the Install now button.
Click the I don’t have a product key option if you are doing a reinstallation. If Windows 11 was previously activated after the installation, reactivation would happen automatically.
Select the edition of “Windows 11” that your license key activates (if applicable).
Check the “I accept the license terms” option.
Click the Next button.
Select the “Custom: Install Windows only (advanced)” option.
Select each partition in the hard drive you want to install Windows 11 21H2 and click the Delete button. (Typically, the “Drive 0” is the drive that contains all the installation files.)

Warning: When you delete a partition, it also deletes all data on the drive. Also, it is not required to delete the partitions from a secondary hard drive.
Select the hard drive (Drive 0 Unallocated Space) to install Windows 11.
Click the Next button.
Select the hard drive (“Drive 0 Unallocated Space”) to install Windows 11 on an unsupported device.

The computer will automatically connect to the network if it uses an Ethernet connection. If you have a wireless connection, you must set up the connection manually (a security key may be required).
(Optional) Confirm a name for the computer.
Click the Next button. (The device will restart automatically.)
Select the “Set up for personal use” option if you are configuring Windows 11 Pro. The “Home” edition does not have this option.
Click the Next button.
Click the Sign in button.
Confirm your Microsoft account email, phone number, or Skype identification to create an account.
Click the Next button.
Confirm your Microsoft account password.
Click the Next button.

Clean install Windows 11 using Reset this PC local image

The recovery settings offer another method to start fresh with a clean copy of Windows 11. Unlike the Media Creation Tool, bootable flash drive, and ISO file options, you can only use this method to reinstall Windows 11 on a computer already running the same operating system.

If you plan to upgrade a computer running Windows 10, Windows 8.1, or Windows 7, you will have to use one of the previous alternative methods.

To clean install Windows 11 with the local recovery image, use these steps:

Open Settings on Windows 11.
Click on System.
Click on Recovery on the right side.
Under the “Recovery options” section, click the Reset PC button in the “Reset this PC” setting.
Click the Remove everything option to perform a fresh install of Windows 11.
Click the Local reinstall option.
(Optional) Click the Change settings option.
Configure the reinstallation options:
- Clean data: If this option is set to No (recommended), then the setup will only delete files, apps, and settings quickly. If the option is set to Yes, the setup will securely clean the drive before installing the operating system, but it will take longer.
- Delete files from all drives: Only the installation drive will be erased if the option is set to No (recommended). Otherwise, if this option is set to Yes, all the drives on the device will be deleted.
- Download Windows: If this option is set to No (recommended), the local image will be used for installation. The “Cloud download” option will be activated if the option is set to Yes.
Click the Confirm button.
Click the Next button.
Click the Reset button.
Select the hard drive (“Drive 0 Unallocated Space”) to install Windows 11 on an unsupported device.
Click the Next button.

Once you complete the steps, the recovery feature will continue with the reinstallation using the locally available image of Windows 11. This process will restore the original settings if you have a computer from HP, Dell, Acer, or another brand. This means the manufacturer included factory settings, drivers, applications, and tools in the custom image.

If you don’t want to reinstall the custom manufacturer image, use the “Cloud Download” option (see steps below).

Clean install Windows 11 using Reset this PC Cloud download

The Reset this PC feature also includes the “Cloud Download” option, which allows you to reset a computer with a clean installation, removing apps, files, and settings similar to the local image option. The only difference is that the feature will download the installation files from the Microsoft server.

The option is available to reinstall Windows 11 when the local image is not working or you do not want to use the same installation settings provided by the manufacturer. If you select the “Cloud download” option, the feature will download the same version already installed on the computer, which means you cannot use this method to upgrade to a newer version. Also, if the device used a custom image from the manufacturer, the new installation won’t include the custom settings, drivers, or tools.

To reinstall Windows 11 with the “Cloud Download” option, use these steps:

Open Settings.
Click on System.
Click on Recovery on the right side.
Under the “Recovery options” section, click the Reset PC button in the “Reset this PC” setting.
Click the Remove everything option to perform a fresh install of Windows 11.
Click the Cloud reinstall option.
(Optional) Click the Change settings option.
Configure the reinstallation options:
- Clean data: If this option is set to No (recommended), then the setup will only delete files, apps, and settings quickly. If the option is set to Yes, the setup will securely clean the drive before installing the operating system, but it will take longer.
- Delete files from all drives: Only the installation drive will be erased if the option is No (recommended). Otherwise, if this option is set to Yes, all the drives on the device will be deleted.
- Download Windows: If this option is set to Yes (recommended), the “Cloud download” option will be used for installation. If the option is set to No, the local image option will be used for the installation.
Click the Confirm button.
Click the Next button.
Click the Reset button.
Select the hard drive (“Drive 0 Unallocated Space”) to install Windows 11 on an unsupported device.
Click the Next button.
Select your region setting after the installation on the first page of the out-of-the-box experience (OOBE).
Click the Yes button.
Select your keyboard layout setting.

Click the Next button.
Click the Decline button to skip the Microsoft 365 setup.
Click the “Skip for now” button to skip the Game Pass subscription promotion.

After you complete the steps, the feature will reset the computer by erasing and reinstalling a fresh copy of Windows 11 downloaded from the cloud.

Clean install Windows 11 from WinRE

If the computer does not boot, the Windows Recovery Environment (WinRE or Windows RE) includes the same options with the “Reset this PC” feature.

You can only use this option to reinstall the same version of the OS already installed on the computer. If you want to upgrade to the latest version, use the USB flash drive, Media Creation Tool, or ISO file options.

To clean install Windows 11 from WinRE, use these steps:

Start device.
Immediately after the Power-On Self-Test (POST), press the Power button again to shut down.
Repeat steps 1 and 2 twice, and in the third restart, the operating system should enter the Windows Recovery Environment (Windows RE).
