Windows 10: Cannot find room for the EFI system partition

Hello, Microsoft forum people.Recently I've been trying to update from legacy bios to UEFI using mbr2gpt command. However non of my attempt actually succeeded. I kept getting an "Cannot find room for the EFI system partition" error over and over again. I tried all the internet solutions I could find, nevertheless nothing helped, which leads me to believe that I have a special case for instance, my boot drive is not disk 0 but disk 2, however I can be wrong as I'm not a poweruser and have very little experience if any.I've linked screenshots of my setuperr.log and disk management sadly, the

MBR2GPT fails with error - Cannot find room for the EFI system partition.

Have you tried running MBT2EFI while in Windows? Normally, the System EFI partition will be placed after the OS partition. If the utility cannot shrink the C partition, it may not be able to add that partition. You do only have 58 GB free in C so I can
see why it might have problems.

It also has to add an MSR partition which is probably 16 MB so there may not be enough room in the 101 MB partition, but just guessing.

 

Move EFI partition

its to enable win 10 to update to its anniversary edition.. it cant do this due to lack of C drive space i have had a quick try with the trial version of easus.. it didnt seem to be able to do what i want..

i am assuming i cant just delete the efi partition but maybe i could.. as yet i havnt even figured out how to get into the bios of the thing.. maybe that should be my next step.. *Smile

diskpart could probably do it but figuring out how (it aint that user friendly) might be difficult without step by step instructions..
