Switching your BIOS mode from Legacy to UEFI for Windows 11 isn’t as tough as it sounds. First, make sure your computer supports UEFI, then change the BIOS settings, and finally convert your Windows installation to the new mode. If done right, you’ll enjoy faster boot times and enhanced security.
Step-by-Step Tutorial: How to Change BIOS Mode from Legacy to UEFI for Windows 11
Switching BIOS modes requires changing settings in the BIOS menu and converting your drive. The following steps will guide you through this process.
Step 1: Back Up Your Data
Make sure to back up your important files before starting.
If anything goes wrong, having a backup ensures you don’t lose valuable data. Use an external drive or cloud storage.
Step 2: Check UEFI Compatibility
Verify if your computer supports UEFI.
Access your BIOS settings and look for the UEFI option. If it’s there, you’re good to go. If not, you might need a BIOS update or a new motherboard.
Step 3: Enter BIOS Setup
Restart your computer and enter BIOS setup by pressing a specific key like F2, DEL, or ESC during startup.
Each manufacturer has different keys, so you might have to look it up. Once in, navigate to the boot settings.
Step 4: Change Boot Mode to UEFI
Find the option to switch from Legacy to UEFI mode and select it.
Save your changes and exit. Your computer will restart, now in UEFI mode.
Step 5: Convert MBR to GPT
Use the built-in MBR2GPT tool in Windows 11.
Open Command Prompt as an administrator and type mbr2gpt /convert /allowfullos. This will convert your drive from MBR to GPT, making it UEFI-compatible.
After completing these steps, your computer should boot in UEFI mode. You’ll notice faster boot times and improved security features.
