Grub2 Icons

Hello,

this is my first post in this forum :)

I'm really a newbie of the OpenSUSE distro.

Currently on my laptop I have installed and configured these OS: OpenSUSE (13.1) (the default OS :D), Ubuntu 14.04, Windows 8.
I noticed that at the boot, grub show me the Windows ICON to the left of the menu string, I'd like to ask you how can I add the other icons for the other OS?
I tried to search inside the forum and I found this link: https://forums.opensuse.org/showthre...tros-boot-menu
But it's seems that it is not applicable to my case since I'm using UEFI boot.
I installed on my gnome desktop the grub-customizer but it doesn't have any option to enable the icon visualization.

Thank you in advance for the help!
Bye
