Kubuntu EFI folder.

[claydoh]

I am having the same issue, EXCEPT on two systems I have, there are BOTH ubuntu AND kubuntu efi directories. Should I start a separate thread?

Probably.
But what do you mean by directories, orrather, where do you see this?

efibootmgr shows the boot items that the BIOS sees, not directories.

I will wager that these two boot items are actually the same exact boot entry, or boot the same thing, rather. Perhaps stale boot files from previous OS installs, maybe.

I've been currently labeling both the root and uefi partitions as boot partitions. I don't know if that is the correct thing to do.

No, only the efi partition (/bootg/efi) uses this.
