So, most common size guideline for EFI System Partition is between 100 MB to 550 MB. One of the reason behind this is it is difficult to resize later as it is the first partition on the drive. EFI partition may contain languages, fonts, BIOS firmware, other firmware related stuffs.
Can UEFI boot MBR?
UEFI enables better use of bigger hard drives. Though UEFI supports the traditional master boot record (MBR) method of hard drive partitioning, it doesn’t stop there. It’s also capable of working with the GUID Partition Table (GPT), which is free of the limitations the MBR places on the number and size of partitions.
