Windows 11 is quite comprehensive with support for older programs dating back to the early days of the OS. However, it can be buggy sometimes leading to issues and background conflicts that can not be solved with a simple uninstall or restart. In most cases, a reset of your Windows OS can help you deal with such issues but sometimes even that goes in vain when you’re dealing with driver conflicts and other complicated issues.

Thankfully you have the option to format your entire drive and start from scratch. A fresh install of Windows 11 will help keep bugs at bay and allow you to set up Windows 11 as intended for your use. Here’s how you can format and clean install Windows 11 using a USB.

Note: Formatting your boot drive or partition will delete all the data contained on it. It is recommended that you back up all your important data from your boot partition or drive before proceeding with the guide below.

How to format Windows 11 using a USB

You can format Windows 11 and perform a clean install using the steps below. We will start by creating the Windows 11 USB using your preferred method and then boot from the same.

This will allow us to format your primary partition. Once the primary partition has been formatted accordingly we can clean install Windows 11 on the same. Let’s get started.

Note: We recommend you keep your product key handy and source it beforehand as it will be needed during this guide.

Step 1: Create a USB

You can create your Windows 11 USB using either Microsoft’s Media Creation Tool or a third-party tool ie: Rufus. We recommend you use Rufus for a traditional Windows install experience. It will also help you modify the USB as intended to bypass Windows 11 restrictions.

You can use the Media Creation Tool if you wish to go the official way and enjoy the entire OOBE offered by Windows 11. Follow either of the methods below based on your current preferences and requirements.

Method 1: Using Media Creation Tool

  • Media Creation Tool | Download Link

Download and launch the Media Creation Tool on your PC using the link above. Once launched, plug in your desired USB and click Accept.

Note: Ensure that your USB drive is empty or does not contain any important data as it will be formatted during this process. 

Your language and Windows edition will be automatically determined based on your current installation. If you wish to change the same, uncheck the box for Use the recommended options for this PC.

Now choose your desired language and Windows 11 edition.

Click Next.

Click and select USB flash drive.

Click Next.

Ensure your USB drive is listed on the next page. Click and select the same.

Click Next once you’re done.

Media Creation Tool will now download the necessary files required for Windows 11 and set up your PC as intended.

Once done, you will be shown the final screen with the message Your USB flash drive is ready. Click Finish.

And that’s it! You will now have created your Windows 11 installation USB using the Media Creation Tool. 

Method 2: Using Rufus

You can also create a Windows 11 USB using Rufus. Rufus is a long-standing third-party tool that has been used to create boot media for various Operating Systems over the years. Here’s how you can create a Windows 11 USB drive using the same.

Start by downloading Rufus to your PC using the link above. Once downloaded, click the link for Windows 11 ISO. Under Download Windows 11 Disk Image (ISO) click the drop-down menu. Select Windows 11 (multi-edition ISO).

Click Download.

Click the next drop-down menu and select your desired language.

Click Confirm once you’re done.

Click 64-bit Download.

A download for the ISO will now be initiated. Save the ISO to your local storage as usual. Once the ISO has been downloaded, plug in the desired USB you wish to use for this process into your PC. Double click and launch Rufus once done.

Click the drop-down menu for Device and select your USB drive.

Note: We recommend you backup data from your USB drive at this point. Any data on your drive will be lost once it is formatted during the Windows 11 USB creation process.

Click SELECT.

Now choose the Windows 11 ISO we downloaded earlier.

Ensure Image option has been set to Standard Windows 11 Installation (TPM 2.0 + Secure Boot).

Set your Partition scheme as GPT.

Ensure Target system has been set to UEFI.

Note: If you’re installing Windows 11 on older hardware by bypassing restrictions then you might have to change this option based on your PC. 

Click START.

Rufus will now start creating your USB. This can take some time, you can grab a cup of coffee meanwhile. Once the process finishes, click Close.

And that’s it! You will now have created your Windows 11 USB using Rufus.

Step 2: Boot from the USB

Note: We recommend you identify your boot drive before booting with your USB. You can do this by noting down the free space on your boot drive and corroborating the same when formatting the drive.

We can now boot from the Windows 11 USB. This will allow us to format our boot drive as needed and then clean install Windows 11. You will need to access your BIOS menu for this process. This will allow us to change our boot device and boot from the USB. You can also use the boot menu instead to manually select and boot from the Windows 11 USB.

Use this comprehensive guide from us to find out the correct key to access your BIOS menu based on your OEM. 

If you’re looking to use the boot menu instead, you can use the Esc key on most PCs to access the same. Once you’re in the boot menu, select your USB and press Enter on your keyboard to boot from the same.

If you’re accessing your BIOS menu then find an option to select your Boot Device. You can find this menu under one of the following names on your PC.

  • Boot menu
  • Boot devices
  • Boot priority
  • Boot device priority
  • Boot Options

Once found, set the USB we created as the first device you wish to boot. Now save your changes and exit the BIOS menu. 

Your PC will now restart and you should now boot from the USB. You can now use the next guide to format your boot drive and clean install Windows 11 on your PC.

Step 3: Format and clean install Windows 11

You should now be greeted by the Windows setup now that you have booted from the USB. Follow the steps below to help you format and clean install Windows 11 on your PC.

Click the first drop-down menu and select your desired Windows 11 language. 

Now click the drop-down menu for Time and currency format and select your preferred region. 

Finally, click the drop-down menu for the Keyboard or input method and select your desired input method or region based on your preferences. 

Once you’re done, click Next.

Now click Install Now.

Enter your Windows 11 product key in the given text box.

If your PC did not ship with a product key and instead uses an OEM Windows installation, then click I don’t have a product key.

Click Next if you have used your product key. 

Click and select the Windows 11 edition relevant to you. 

Click Next.

Now accept the license agreement by checking the box for the same.

Click Next.

Click and select Custom: Install Windows only (advanced).

You will now be shown a list of all the partitions currently available on your PC. Follow one of the sub-sections below depending on the partition you wish to format. 

Format only your boot partition

Formatting your boot partition is a simple procedure. We will simply format the primary partition containing the Windows OS. This will allow your Recovery and System partitions to remain intact which will allow you to access your OEM files as intended.

This is the recommended solution for pre-built systems and laptops which have a custom recovery drive setup based on their model. Follow the steps below to help you along with the process. 

Click and select your primary partition from the list on your screen. You can check the Type column and then click and select your primary partition accordingly.

Note: If you have multiple drives on your system, then ensure you select the Primary partition for your boot drive. You can identify your boot disk by looking for System and Recovery partitions. The disk with these partitions is likely your boot disk unless you have multiple operating systems installed on your drives.

Click Delete at the bottom.

You can also delete your system and recovery partition if you wish to start from scratch and do not have custom data in your Recovery partition. Select the desired partitions and click Delete for them as well.

Now click and select the Unallocated Space on your drive.
