It depends on firmware, but I expect that UEFI spec describes
requirements for ESP in the case of MBR partitions.
btw what is recommended size of efi partition?
default size is 512M
sgdisk(8)
* Boot disks for EFI-based systems require an EFI System
Partition (gdisk internal code 0xEF00) formatted as
FAT-32. I recommended making this partition 550 MiB.
(Smaller ESPs are common, but some EFIs have flaky FAT
drivers that necessitate a larger partition for reliable
operation.) Boot-related files are stored here. (Note
that GNU Parted identifies such partitions as having the
"boot flag" set.)
A week ago Jeffrey posted the following link
