Windows 10: mbr2gpt.exe not working

I have been having a problem with my new PC, being that I can't connect to the Internet via the Ethernet port on the motherboard. After talking to tech support, I've realized that I need to convert my drive, with a System, Windows (C), and Recovery partition, to the GPT format to get my Ethernet issue fixed. However, attempting to run "mbr2gpt.exe /convert /disk:0 /allowFullOS" with BitLocker disabled gives me the error, "Cannot find room for the EFI system partition" even with 2 GB of unallocated space on the drive, which I'd assume is enough. How should I fix this issue?

MBR2GPT

I also think so.

Windows upgrade 1903 automatically created a 450 mb recovery partition which I had to delete as mbr2gpt don't work with more than 3 primary partition.

So, do I need to create a recovery partition now to get mbr2gpt work?

I have already tried what you told. It says something like "can't enable win re service "

 

MBR2GPT not working

I ran mbr2gpt from elevated command prompt:
PHP Code: C:\WINDOWS\system32>mbr2gpt /allowfullos /validate /disk:0
MBR2GPT: Attempting to validate disk 0
MBR2GPT: Retrieving layout of disk
MBR2GPT: Validating layout, disk sector size is: 512 bytes
Cannot find OS partition(s) for disk 0

C:\WINDOWS\system32>mbr2gpt /allowfullos /validate /disk:1
MBR2GPT: Attempting to validate disk 1
MBR2GPT: Retrieving layout of disk
MBR2GPT: Validating layout, disk sector size is: 512 bytes
Disk layout validation failed for disk 1

 

mbr2gpt

Your computer is already booting in UEFI mode which means the drive is probably already in GPT format. What makes you think it isn't?

What does diskpart, list disk show?
