Reinstalling Windows 11 from boot is pretty straightforward. First, make sure your data is backed up because this process will wipe your system clean. Youโll need a USB drive with at least 8GB of space, which will be used to create a bootable Windows 11 installation media. Once thatโs ready, youโll restart your computer, boot from the USB, and follow the on-screen instructions to reinstall Windows 11. By the end, your system will be as good as new, ready for you to set it up and start fresh.
How to Reinstall Windows 11 from Boot
Reinstalling Windows 11 from boot essentially gives your computer a fresh start with a clean version of Windows. This can resolve major issues or simply help declutter your system. Letโs walk through the steps.
Step 1: Backup Your Data
Before you begin, itโs crucial to save your important files elsewhere.
Whether itโs through an external hard drive, cloud service, or another computer, make sure all your documents, pictures, and other essential files are backed up. This step ensures you donโt lose anything important during the reinstall process.
Step 2: Create a Bootable USB
Use a blank USB drive with at least 8GB of storage and Microsoftโs Media Creation Tool to make bootable installation media.
Download the Media Creation Tool from Microsoftโs website, and follow the instructions to create a Windows 11 bootable USB. This tool will download the necessary Windows 11 files and prepare your USB drive for installation.
Step 3: Change Boot Order
Restart your computer and enter the BIOS or UEFI firmware settings to set the USB as the primary boot device.
Every computer is a bit different, but usually pressing F2, F12, Delete, or Escape during startup takes you to the BIOS/UEFI settings. From there, navigate to the boot menu and prioritize the USB drive.
Step 4: Start the Installation Process
Insert your bootable USB and restart your computer to start the Windows 11 installation process.
When the computer boots from the USB, it will launch the Windows Setup. Youโll need to select your language, time, and keyboard preferences before clicking โNextโ and then โInstall Now.โ
Step 5: Follow On-Screen Instructions
Complete the installation by following the prompts, including entering your product key if required.
The setup will guide you through the process, including selecting the drive where Windows will be installed. If youโre doing a fresh install, you might need to delete existing partitions, which is usually an option labeled as โCustom: Install Windows only.โ
Once youโve completed all these steps, Windows 11 will begin installing onto your computer. This can take some time, but when finished, youโll go through the initial setup, such as creating a user account and connecting to Wi-Fi. Your computer will feel brand new and ready for a fresh start.
