Cannot find room for the EFI system partition.

C:\WINDOWS\system32>MBR2GPT.EXE /convert /allowfullos



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!

Cannot find room for the EFI system partition when trying to do mbr2gpt

I've been trying to convert my system partition from mbr to gpt but every time I do try it gives this error:

Cannot find room for the EFI system partition.

MBR2GPT: Conversion failed

No tutorials in YouTube match my problem so I am asking here. I was also wondering if the paragon partition manager is a safe way to convert my partition from mbr to gpt.

 

How do find room for EFI system partition?

I've been trying to convert my Legacy bios to UEFI, to access secure boot and update to windows 11. I've been trying with to convert my disk using the mbr2gpt method, but I keep getting Can not find room for the EFI system partition. I've tried shrinking my C: and have 5gb of unallocated space, yet it is not working.
