Yes I did install the system with uefi boot and yes I see the *(asterisk) with the selected and saved boot option.
If you read my last post I showed output of what the /boot/efi/EFI directory looks like, I have attached two screenshots where you can see I'm using uefi and the asterisk on the selected boot option.
Code:
##CUSTOM##
# Uncomment to make GRUB boot from saved selection
GRUB_DEFAULT=saved
# Uncomment to make GRUB remember the last selection. This requires
# setting 'GRUB_DEFAULT=saved' above.
GRUB_SAVEDEFAULT=true
Lastly here's a
link to the grub configuration on the system.
The article just explains what uefi is and where the uefi files are located on different operating systems, you don't have to know much about uefi to use it. I first installed Windows, then afterwards I installed Ubuntu, during installation the uefi part is done by the installer. As in my earlier post that looks like this under Ubuntu.
The main efi directory.
Code:
tux@ubuntu:~$ lsb_release -r
Release: 21.04
tux@ubuntu:~$ sudo ls /boot/efi/EFI

During the installation of Ubuntu when installing grub it detects there is another OS present and installs the efi directory and files for Windows for you. If were to install another Linux distribution along side Windows and Ubuntu it would then automatically place the uefi files in another sub-directory of /boot/efi/EFI
