Why Deepin installition is different

[Yousi]

Why when I install any Linux distribution in uefi
I create to it efi partition with type fat32 mounted by /efi/boot to make it boot while in deepin installition I create efi partition with type is efi without mounting
So if I want to dual boot deepin with another Linux distribution and also windows what should I do as I read that creating more than one efi partition on the same hard can cause problems
