posted on April 10, 2025

Reinstalling Windows 11 from a USB might sound like rocket science, but it’s quite straightforward once you know the steps. First, you need to create a bootable USB drive with the Windows 11 installation files. Then, plug it into your PC and restart your computer. You’ll need to access the boot menu to prioritize the USB drive. Follow the on-screen instructions to reinstall Windows 11. It’s a handy skill to have, especially if your system is acting up or you want a fresh start.

How to Reinstall Windows 11 from USB

This guide will walk you through reinstalling Windows 11 using a USB drive. By the end of these steps, your computer will have a fresh installation of Windows 11.

Step 1: Create a Bootable USB Drive

Get a USB drive with at least 8GB of space and download the Windows 11 installation files onto it.

You’ll need a tool like the Windows Media Creation Tool to make your USB drive bootable. Just follow the prompts to download and save the Windows 11 files onto the drive.

Step 2: Insert the USB Drive

Plug the bootable USB into your computer’s USB port.

Make sure your computer is completely powered off before you plug in the USB. It needs to be in a USB 3.0 port, if possible, for faster installation.

Step 3: Restart Your Computer

Turn on your computer and immediately press the key to enter the boot menu (commonly F12, F2, or DEL).

The key to access the boot menu varies by manufacturer, so a quick Google search with your PC’s model should help if you’re unsure.

Step 4: Select USB Drive from Boot Menu

Use the arrow keys to select the USB drive from the list of boot options and press Enter.

This action tells your computer to boot from the USB drive, not your hard drive, so the installation process can begin.

Step 5: Follow Installation Instructions

Once the Windows setup screen appears, follow the on-screen instructions to complete the installation of Windows 11.

You’ll be prompted to choose your language, time, and keyboard preferences first. Then, select "Install Now" and follow the remaining instructions.

After completing these steps, your computer will restart, and you’ll be greeted by the Windows 11 setup screen. You’ll have a new, clean installation of Windows 11, ready for setup and customization.
