GPT convert does not work well with MBR2GPT.exe

Question

I tried converting MBR to GPT using MBR2GPT.exe on Windows Server 2019, but it ended without a success message or an error message.
I also checked the log file, but I don't see any error messages. Even after booting into WinPE, it is the same. how can i solve it?

C:\Users\Administrator>mbr2gpt /convert /disk:0 /allowfullos

MBR2GPT will now attempt to convert disk 0.
If conversion is successful the disk can only be booted in GPT mode.
These changes cannot be undone!

Hello there,

"MBR2GPT.exe" is a specific utility provided by Microsoft as part of Windows 10, starting with version 1703, which allows users to convert a disk from MBR (Master Boot Record) to GPT (GUID Partition Table) without data loss. It's used in the context of disk partitioning and booting.

If you are facing issues with "MBR2GPT.exe," it's likely related to the operation of that utility itself or how it is being used, rather than any limitation of the GPT model. To troubleshoot any issues with "MBR2GPT.exe," you may want to check Microsoft documentation, support forums, or seek assistance from relevant technical communities.

Keep in mind that advancements in language models and software may have occurred since my last update, so it's always good to verify information with more recent sources.

I used AI provided by ChatGPT to formulate part of this response. I have verified that the information is accurate before sharing it with you.
