Its the startup bios that supports boot mode. once they move from legacy to
UEFI your older mbr drives will not boot.

I'd guess that, even with UEFI replacing legacy BIOS, bootable USB sticks
with MBR partitioning will still be bootable, subject to the underlyimg OS
being otherwise compatible with the hardware.
