The standard is for EFI to look for that partition on all disks, even hard disks. If there are a few broken systems that do otherwise, they could use other methods, but keeping things mostly standardized seems like the best way to go. It&#x27;s how Windows does it, it&#x27;s how FreeBSD does it, it&#x27;s how OpenBSD does it, etc. Mucking around with it doing otherwise is just asking for problems.
