before you do anything, make a bootable clone. at some time in the future you'll be glad you did.
second--make sure you have a working USB boot stick. if you are successful installing windows, it will mess with the /Clover/Boot folder in the EFI partition on your HD/SSD. you will need to boot Mac OS using the USB stick so you can get into the /Clover/Boot/Microsoft folder and make one change. if you get that far I'll tell you what to do.
then:
before trying to set up dual boot, I would give Bootcamp a try.
since forever, up until the last couple of versions of windows 10, it had been fairly easy to dual boot on the same hard drive.
what I did many times:
formatted a HD using Disk Utility, creating a partition for Mac and a partition, formatted MS-DOS, for windows.
install Mac OS and get it running to your liking. make a working backup.
then use the windows installer (created on a USB with Rufus, or nowadays, with MS's installer creation tool).
in the windows installer when you get to the "where to install" screen, the installer will say you can't install windows on the partition you created for windows because it is MS-DOS. (old versions of disk utility let you create a partition as free space and windows was quite happy installing there.). delete the partition, which will change the partition to "unallocated space", highlight the Unformatted Space partition, and then click Format at the bottom of the window and you're good to go.
the problem I've had for the last couple of windows 10 versions is that the windows 10 installer won't proceed because it says the disk was created in MBR style rather than GPT. of course that isn't the case, but windows won't proceed.
I needed to make this work on my hacked laptop which only has one HD. it took me a couple of days, using GPartEd, windows disk management window, and more patience than I normally have, to figure out how to get it done. I didn't document the process, and there is no way I can recreate it for you.
so give it a try if bootcamp doesn't meet your needs, but be prepared for a battle with the windows installer.
Did you try this? if not, I can try and assist
