Setup exactly the same as what the OP has, 2 Windows and 2 EFI System Partitions on physical disk. No VM, no VHDX then come back and prove me wrong.Sure you can have two efi partitions on same drive. Why bother though.
I tested it on a vm, and I could see both in bios, and whichever one I selected was one adjusted when I ran subsequent bcdedits.
LOL, It's easy to make a statement like this. Please show me where you get the Info/Documentation from ???You would be mistaken.

Here you go. Physical disk 1 is the system disk. Two EFI System Partitions. The first boots into Windows 11. The second boots into Windows 10. Selected from the BIOS boot manager. Anything else before I head back to the beach?
Windows 11 booting from the first EFI System Partition on disk 1:
Windows 10 booting from the second EFI System Partition on disk 1:
BIOS boot menu to pick which EFI System Partition to boot from:
![]()
Is that the sound of crickets chirping I hear in the background?
NavyLCDR:
I wonder why mine does not work. W10 boots direct from the Bios Boot Menu, but W8.1 doesn't.
I tried a single physical drive of GPT type on which only W8.1 is installed, and found the problem symptom is the same as above.
Comment or suggestion appreciated.

Suggestion - listen to all advice that says have single EFI partition with a boot menu. There is absolutely no point in having two efis on same drive. You have totally failed to say why you want two EFIs and boot via bios menus. It over complicates things, messes up partition layout, and will probably break at next major upgrade.
