Shrink your APFS container by the amount you want to dedicate to Win10. Create a partition in that space format FAT with Mac disk utility. At the Win10 install screen select this partition and delete it. Select this free space, click on create new partition and format NTFS. Install Win10 to this partition.
I can't get any of the above methods to work. I tried it on a new drive using the command line commands (albeit it didn't recognise some of the syntax so I had to lose specifying the file system in the create primary partition line, and I had to lose the format and label properties when creating the EFI drive but otherwise it all worked). However, when it came to actually installing windows on the newly formatted primary partition, I got the error message from the Win 10 installer that it was a GPT partition. I have tried installing Windows 10 on the Samsung 960 Evo that I used to have Windows installed on (but inadvisably wiped lol) and now I just can't get it to work. I also tried my Samsung 850 Evo and that didn't work either. I tried either installing into unallocated space or a correctly created set of partitions created by the win installer itself, using either my licence key, or without a licence key, and none has worked. I tried using the install DVD as well as a USB installer (created by Microsoft's exe), and neither were successful. There doesn't seem to be any difference in performance between the DVD and USB, if I create a DVD from the genuine Windows 10 iso. When it comes to actually booting up the installer, I've tried with and without CSM Support enabled, no difference in the end failure to install Windows. It also seems the BIOS doesn't boot up the UEFI part of the installer DVD unless I set the installer at boot order no.1 in the BIOS, if I just select the DVD and save and exit it doesn't load it up. I can start the DVD from Clover but not the USB installer, that has to be done from the BIOS boot order. The only thing left to try I think is to give up on UEFI and try formatting a dedicated drive to MBR and trying to install Win 10 on that.
