    Ix07 has Operating systems confused on what a Bootloader is. The BIOS/MBR Boot Process Mac OS Darwin used to use BootX with the PowerPC, now uses Boot.efi like Windows does. Only one bootloader can be used to get input from the user as to what OS that they wish to load up or have automatically loaded.
    I really am not. My rEFInd bootmanager can for example call Syslinux loader to load Linux in MBR mode or GRUB2 in EFI mode (on the same volume), or Windows via CSM or OSX via EFI. Once this second is bootloader is loaded it can then call another - this is called chainloading. If I feel like it I can go from rEFInd to Syslinux to Windows, back to Syslinux, back to Windows for ever and never actually boot anything.

    Your link is not relevant to UEFI although with a hybrid member you can (and I do) call a VBR based loader from EFI - I have Syslinux installed on the volume (partition) boot record not on the MBR. The only reason you would use a hybrid member is if you had a real Mac from before 2008 with their peculiar EFI 1.1 implementation which will not boot Windows on a GPT partition.

    We really need to see a screenshot of disk management to determine what is going on, rather than just blindly guessing.
    NavyLCDR, here is a diskpart and a diskmanagement screenshot.
    Win10 on the C drive, works and boots fine.
    Win10 on the D drive is not booting.
    Clover is on the E drive.
    The diskpart says that the boot section is on the C drive

    First step would be to open a Command Prompt (Admin) or Powershell (Admin) and run:

    bcdboot D:\Windows /d /addlast

    then reboot the computer.
