Hey Sergey SUCCESS.! Sort of ;o). Sorry for the late reply, thank you so much for taking the time to produce a video, that was very much appreciated. It is actually frustrating as I had an opportunity to initialize the disk in macOS when I first instilled it, however I cancelled and waited till I was in Windows and initialized in Diskpart, as I am more familiar with Diskpart. I had no idea windows GPT formatting was different to Mac GPT formatting, though I should have known better as I have been...

Hello Sargey, me again ;o) Please do not feel the need to rush a reply, I have plenty of time for this project, only respond when you can. Unfortunately no success with achieving a bootable system, as advised I formatted the drive to the exact size disk1s1 200/209.7Mb, I have tried formats fat32, exfat, ntfs, and tried partitioning as primary or system, every which way I know. Toward the end of the process the Window Install app unmounts the efi partition but output still states efi not found. I...

Hi Sargey, thanks for taking the time to reply so quickly, Wow that is some translator, your information is coming across word perfect, and I have had no trouble understanding everything you have written so far. I am done for today and shall try again tomorrow. As you suggest I shall pull all unnecessary drives, which is what I usually do if installing form a flash drive, but as you have said the existing efi is part of the macOS system used to create the Windows install, so that will need to remain...

@Sergey_Gaian Hi Sargey – thanks for taking the time to reply, I don’t take help form others lightly and appreciate how busy people are, so I try to understand and do as much as I can before troubling others. I had previously attempted to do what you suggested as I read the information displayed in the Window app dialog before pulling in the iso, however I must be misunderstanding something that you, Lance and others have worked out, I initially posted on MacSounds as I could see the efi was missing...

@Sergey_Gaian Hi Sergey, thanks for reaching out on MacSoundSolutions. Both you and Lance along with OCLP are doing humanity a great service, otherwise I would have to bow out as I do not have the cash to keep feeding greedy corporate animals renewing hard/software every other year.! - Btw, fantastic tip using spacebar with OC, I would never think to do that as users are to busy choosing a system to boot. The spacebar may have invitingly solved a separate issue for me, I have issues with some keyboard...
