Bootcamp won't partition (Win 10) iMac late-2012 Fusion Drive Mojave

Hello Loner T,


I followed your steps by steps from your answer at https://discussions.apple.com/thread/8483965?answerId=33706642022#33706642022 but Bootcamp keeps failing at partitioning my Fusion drive.


My config:

iMac Late-2012 1TB Fusion Drive

10.14.5

I used to have Bootcamp working like a charm with Win 7. Yesterday, I decided to remove the Win 7 partition (through Bootcamp with success) to start a clean install of Win 10 Pro 1903 x64. However, Bootcamp won't partition the HD again. I was able to partition it through Disk Utility but then, Windows 10 installer won't allow me (the famous GPT error).


(I made sure I don't have anything else plugged beside the keyboard, mouse and WinInstall USB2 thumb drive)


Would you or anyone else able to help me on this matter?
