ok, so UEFI loads grub which loads grub.cfg which knows about the different kernels ?
Essentially, yes. UEFI has its own list, which normally isn't displayed and is only available with the F12 key. It identifies different boot loaders (such as the PXE loader, the Windows boot loader, grub2, etc).
I will try to hit F12 next time I boot... I want to SEE this:)
I just mounted my ubuntu "/" partition and.... /boot/efi was... empty. I'm pretty sure it was there when I booted ubuntu.. oh wait... /boot/efi is a separate partition.. but it is already mounted, and it is fedora, not ubuntu... arg....
Yeah, you will typically have just one system partition. In your case, it has different directories for the Fedora and Ubuntu shim and grubx64.efi, and grub.cfg.
that's what is confusing.. I remember under ubuntu there was a /boot/efi/EFI/ubuntu folder.. /boot/efi is a separate partion, I get that, I created it:)
but now I don't see the ubuntu folder, but the fedora folder.. do these folders get created/and/or/mounted differently for each OS??
ls -l /boot/efi/EFI total 16 drwx------ 2 root root 2048 May 21 14:59 BOOT drwx------ 3 root root 2048 Aug 27 06:40 fedora -rwx------ 1 root root 11391 Aug 23 09:02 fedora.new
