A correctly-written PC BIOS does not even look at (or for) a partition
table of any sort when booting.  That's been the case for a
quarter-century.   A system that does not boot without the active bit
set is buggy, not new vs. old.

In a PC architecture the boot code in the MBR is the first thing that
care about the partition table and active bits.
