You will need to use BC Assistant to remove the current EFI installation first.
Reset SMC and NVRAM.
Once removed, use a USB2 (not USB3) Flash drive, create Create+Download+Install and follow prompts.
Your Mac is a preUEFI Mac.
If you are on Mojave, you will need to first use Create+Download.
Use Disk Utility to create a FAT32 partition of the size you want Windows to be.
You will need to use GPT Fdisk to create a hybrid MBR manually.
You can now connect the USB2 , and select the Windows (not EFI) icon and try to install Windows.

Post any errors at any point and stop.
