I think that's a Windows limitation, but as the OP /has/ Windows, it's true for the OP. It may be even more true for the OP in view of their intention to try and create their ESP in a logical partition, rather than a primary one. But it seems to be all moot now. I'm pretty sure the OP will create a GPT scheme on their second attempt. https://superuser.com/questions/1067709/booting-with-mbr-in-uefi-no-csm-mode-at-all Cheers, David.
