Most EFIs, including Apples, include their own boot managers however, these built-in boot managers are usually very primitive. I do not think you read the question before reading my answer.Ī boot manager presents a menu or some other user interface tool to enable you to select which OS to boot. The steps given in the answer start where the OP left off in the posted question. There is no limit to the number of EFI partitions you can have.Īn example, of a second EFI partition, can be found at this answer. However, I have a feeling that putting the icon where you specified just makes it the default icon because putting the icon in the root of the Ubuntu partition didnt work. The Mac icon appears for Mac HD and the Ubuntu one for the other partition. Therefore, Ubuntu 18 and later users should be able to skip steps 5 and 6. The process of making the Ubuntu appear on the Startup Manager is a fairly trivial.
