🔄 How to Switch from Legacy BIOS to UEFI in Windows 10/11
Want to enable Secure Boot but your BIOS is set to Legacy? Here’s how to safely convert your system from Legacy BIOS to UEFI without reinstalling Windows:
🛑 Before You Begin
• Back up your files just in case
• Make sure your PC supports UEFI (most systems from 2012 or later do)
✅ Step-by-Step Instructions
1. Check Your BIOS Mode and Disk Type
• Press Windows + R, type msinfo32, and press Enter
• Look for BIOS Mode — if it says Legacy, continue
• Open Disk Management by right-clicking the Start button
• Right-click your system disk (usually Disk 0), select Properties, then go to the Volumes tab
• Check Partition Style — if it says MBR, you're ready to convert
2. Convert MBR to GPT (No Data Loss)
• Open Command Prompt as Administrator
• Run this command to validate:
mbr2gpt /validate /allowFullOS
• If validation is successful, run this to convert:
mbr2gpt /convert /allowFullOS
• You should see a message like:
"Before the new system can boot properly, you need to switch the firmware to boot to UEFI mode"
3. Reboot and Switch to UEFI in BIOS
• Hold the Shift key and click Restart from the Start menu power options
• On the blue screen, go to Troubleshoot
• Select Advanced Options
• Choose UEFI Firmware Settings, then click Restart
• Once in BIOS, look for Boot Mode
• Change it from Legacy to UEFI
• Save and exit (usually by pressing the F10 key)
4. Confirm the Change
• Once back in Windows, open msinfo32 again
• BIOS Mode should now show UEFI
Still can't enable Secure Boot?
Check your BIOS for a setting called CSM and disable it first.
