I will try to hit F12 next time I boot... I want to SEE this:)

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


where in the world is ubuntu ( not Carmen san Diego:-0)
