Back Up Your Data: A Crucial First Step
Before you proceed with formatting your C drive, it’s absolutely essential to back up all your important data. This includes:
- Documents: Your personal files, photos, videos, and other documents.
- Applications: If you have any essential software that’s not pre-installed with Windows, create a backup of its installation files.
- Settings: Back up your system settings, including your Wi-Fi passwords and personal preferences.
You can use various methods for data backup:
- External Hard Drive: A reliable and convenient option for large amounts of data.
- Cloud Storage: Services like Google Drive, OneDrive, and Dropbox allow you to store your files online.
- USB Flash Drive: Suitable for smaller files and backups.
Creating a Bootable USB Drive: Your Installation Key
To reinstall Windows 11, you’ll need a bootable USB drive containing the installation files. Here’s how to create one:
1. Download the Windows 11 ISO: Visit Microsoft‘s official website and download the Windows 11 ISO file.
2. Use a USB Drive Formatting Tool: Tools like Rufus or the Media Creation Tool (provided by Microsoft) can help you format your USB drive and create a bootable installation medium.
3. Format the USB Drive: Select your USB drive and choose the appropriate formatting options.
4. Select the Windows 11 ISO: Choose the downloaded ISO file as the source for the installation.
5. Create the Bootable Drive: Start the process and wait for the bootable USB drive to be created.
Accessing the BIOS and Boot Menu: Setting the Stage
Once your bootable USB drive is ready, you need to access the BIOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface) of your computer. This is where you’ll tell your computer to boot from the USB drive instead of the hard drive.
1. Restart Your Computer: Turn off your computer and restart it.
2. Press the BIOS/UEFI Key: Immediately after restarting, press the designated key to enter the BIOS/UEFI setup. The key varies depending on your computer’s manufacturer (usually F2, F10, Del, or Esc).
3. Navigate to the Boot Menu: Use the arrow keys to navigate to the Boot menu within the BIOS/UEFI settings.
4. Select the USB Drive: Choose the USB drive you created as the boot priority.
5. Save and Exit: Save the changes and exit the BIOS/UEFI setup.

1. Language and Keyboard Selection: Choose your preferred language and keyboard layout.
