A bit more precise:
“Anaconda will no longer support installing in UEFI mode on MBR-partitioned disks for X886. While the UEFI specification technically permits booting from MBR (msdos) disks, in practice this configuration is unreliable, inconsistently supported by firmware, and not tested in Fedora.”
which I think is the proper thing to do.

Thank you for the clarification! I don't super understand your clarified version either but it helps me conclude this seems unlikely to be important to me or affect my use case 😅
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.
nobody used it like that anyways
