The new Intel UEFI-only BIOSes actually only restrict the INTERNAL disk to UEFI-only booting - they will still allow MBR-boot from external USB media (so they can boot to a DOS BIOS Flash program, for instance).
You can use SWITCH_E2B.exe first to switch in any .imgPTN file.
It is possible to UEFI-boot from an E2B drive BUT many BIOSes have bugs which means that a BIOS will always UEFI-boot from the E2B drive and will NEVER MBR-boot to the Legacy E2B menu even if you enable CSM in the BIOS Settings.
I recommend you look at http://www.easy2boot.com/add-payload-files/refind/ and eBook #3.
