It shouldn’t, you probably have a modern setup. Super high level is that: UEFI is like a mini os on the mainboard, replacing the old bios chips that were very limited, including on partitions on disks: max 2 physical (whereby the 2nd was used to embed “soft” partitions), and any boot code was confined to cramped spaces, below certain amounts of blocks and cylinders etc, hence the peculiar /boot partition. UEFI had to support this of course, but it’s at best like wearing clothes that you accidentally washed at the highest temperature: bleak, way too tight in uncomfortable places and prone to tearing.
