How to Reinstall Windows 11
Reinstalling Windows 11 involves a straightforward process that will restore your computer to its prime. Follow these steps, and soon you’ll be operating on a fresh, clean system.
Step 1: Backup Your Data
Before you begin, make sure to back up all important files and data.
This ensures that you won’t lose any crucial documents, photos, or other files during the reinstallation process. Use an external hard drive or a cloud storage service like Google Drive or OneDrive to safely store your files.
Step 2: Create a Windows 11 Installation Media
Create a bootable USB drive using the Windows 11 Installation Media tool.
Go to the official Microsoft website and download the Media Creation Tool. Follow the on-screen instructions to create a bootable USB drive with at least 8 GB of space. Make sure to label it clearly for easy identification.
Step 3: Boot from the USB Drive
Insert the USB drive into your computer and restart it to boot from the USB.
You might need to enter the BIOS setup to change the boot order. Look for an option like "Boot from USB" and select it. This will start the Windows installation process.
Step 4: Reinstall Windows 11
Follow the on-screen instructions to reinstall Windows 11.
Choose the "Custom: Install Windows only (advanced)" option for a fresh installation. This will wipe your current Windows installation but keep other partitions intact.
Step 5: Restore Your Files
Once Windows 11 is reinstalled, restore your backed-up files.
Connect your backup device or login to your cloud storage to retrieve all your important files. Ensure everything is back where it belongs, and check that all software you need is reinstalled.
After completing the reinstallation, your computer will be running like new again. Windows 11 will boot up, leading you through initial setup options like region, keyboard layout, and connecting to Wi-Fi. You’ll enjoy faster performance and a clutter-free system.
