I had to create an EFI partition to install ubuntu 18.04. Now I want to create another boot on the same HD with 18.04 again. Do I need to create another EFI partition?

system-installation uefi

    No, you only need one EFI partition. My dual-boot system shares the one partition between Windows and Ubuntu.

    You can see it here with all the goofy Windows partitions. (My / partition is on a different physical drive)

  2. You need only one EFI partition for a computer in general.

    No matter how many OS you have.

    You may need multiple EFI partitions only in some special cases when you swap disks, change boot device in UEFI, etc.
