Using MBR2GPT to Enable UEFI Mode and Secure Boot

Transitioning your system to UEFI mode is essential to enable Secure Boot, a key requirement for Windows 11. While certain registry keys can bypass other Windows 11 prerequisites, Secure Boot must be enabled through UEFI. This article provides a step-by-step guide to using MBR2GPT to convert your disk from MBR to GPT, enabling UEFI mode and Secure Boot.

Introduction

Secure Boot is a crucial security feature required for Windows 11. To enable Secure Boot, your BIOS must support UEFI. Ensure you can activate this option before proceeding with the conversion process.

Procedure

1. Disable BitLocker (if enabled):
   • Open the BitLocker Management settings and turn off BitLocker for your drive.
2. Enter Windows Recovery Environment (WinRE):
   • Start your Windows system.
   • Press and hold the Shift key and click on Restart from the Start menu. This will boot your system into WinRE.
3. From WinRE:
   • Click on Troubleshoot > Advanced Options > Command Prompt.
4. Run MBR2GPT Command:
   • In the Command Prompt window, type the following command to validate your disk:cmdCopier le codembr2gpt.exe /validate
   • If validation is successful, convert the disk by typing:cmdCopier le codembr2gpt.exe /convert
5. Enable UEFI and Secure Boot in BIOS:
   • Restart your computer and enter the BIOS setup (usually by pressing a key like F2, F10, Del, or Esc during startup).
   • Navigate to the Boot settings.
   • Enable UEFI mode.
   • Enable Secure Boot.
