The DE MBR to GPT tool (
MdeMbr2GptTool.exe) works on Microsoft Windows 10 (version 1703) Creators Update and later (64-bit only). The tool works with the Microsoft
MBR2GPT.EXE tool, to convert a software-encrypted DE drive, from
Master Boot Record (MBR) to the
GUID Partition Table (GPT) partition style, without the need to decrypt the disk. For more information about Microsoft
MBR2GPT.EXE, see
https://docs.microsoft.com/en-us/windows/deployment/mbr-to-gpt

Comments |
| MdeMbr2GptTool.exe |
McAfee MBR to GPT conversion executable. |
| MdeMbr2Gpt.bat |
Batch file to in initiate the conversion. |
| MfeEEBoot32.efi |
32-bit UEFI boot file. |
| MfeEEBoot64.efi |
64-bit UEFI boot file. |
| HWDefaultProductDetections.xml |
Hardware Compatibility XML file. |
IMPORTANT:
- The tool must be run from an administrator command prompt.
- The MdeMbr2GptTool.exe looks for the Hardware Compatibility XML file called HwDefaultProductDetections.xml in the same directory. But, a specific file can be provided with the command-line switch -HWCompatXml using the convert command.
Example: MdeMbr2GptTool convert -HwCompatXml c:\Tools\HWCompat.xml
IMPORTANT: To obtain the latest Hardware Compatibility XML file, see KB81900.
- The tool allows conversion of any Windows 10 (version 1703) Creators Update and later from MBR to GPT that is encrypted using DE software encryption. To view supported versions of Windows 10, see KB85784.
- The tool only supports 64-bit platforms.
- The tool does not support conversion of Opal encrypted systems
- Once the Microsoft tool MBR2GPT.EXE has been run, any subsequent failure prevents the system from booting. There is no easy way to recover, even using the DE recovery tool DETech. On any critical system, taking a sector by sector backup, is highly recommended.
- The tool only works from the Windows desktop from the system being converted (no WinPE support).
- The tool only works on active encrypted systems.
