MBR2GPT will now attempt to convert the default book disk.
If conversion is successful the disk can only be booted in GPT mode.
These changes cannot be undone!

/validate
- Validates that the selected disk can be converted
without performing the actual conversion.
/convert
- Validates that the selected disk can be converted
and performs the actual conversion.
/disk:<diskNumber>
- Specifies the disk number of the disk to be processed.
If not specified, the system disk is processed.
/logs:<logDirectory>
- Specifies the directory for logging. By default logs
are created in the %windir% directory.
/map:<source>=<destination>
- Specifies the GPT partition type to be used for a
given MBR partition type not recognized by Windows.
Multiple /map switches are allowed.
/allowFullOS
- Allows the tool to be used from the full Windows
environment. By default, this tool can only be used
from the Windows Preinstallation Environment.
My understanding is that mbr2gpt can only be converted during installing windows, Windows Preinstallation Environment.
Which bring me back to the requirement to enable UEFI on BIOS afterward.
Read on aforum that w11 MCT will only install on GPT mode and done.
But on Windows support there is a warning about having to enable uefi on BIOS too, wondering that it only apply to W 10 as by default it install on MBR.
