The only intention to open this topic is try to solve questions of new users of Grub4dos for UEFI, and give them certain guidance (as far as possible) as so far there is not any official guide for it.
IMHO the official topic GRUB4DOS for UEFI created by our felow a1ve to let all us know about this new tool is now very long and it is becoming hard to read, as at the begining the firts tests we ran were unsucessful and the program has being modified a lot from the first version, so then the info on the very first post is not the current info anymore, and this is a recurrent phenomenon on that topic, caused for changes on new versions of the tool.
In no way this is a dissimulated intent to bypass the moderator of this forum section, in fact I publicly recognize my actions related to this topic were wrong. How I can request a moderator to keep order if I don't comply myself keeping the order in first place? So I already talk with Wonko by Private Messenger about this, and we both are agree there are no hard feelings about this subject.
I think this tool is now more mature and future changes will not be so drastic, so it seems to be the right time to start this topic.
On following posts it is very possible I will quote or add links to other relevant info from the topic GRUB4DOS for UEFI that are still valid and a good reference.
A good start is read following guides from liuzhaoyzz:
But I stronly suggest DO NOT intent make use of hot keys, colored menus or change default screen resolution, for now just avoid that on your menus, as there has being many changes in those features since the guides were created.

I invite all the forum members with solid knowledge about this subject to join me in this topic to try to solve questions or doubts of new users of this tool.
But I kindly ask all users to avoid posting about other procedures that require to additionally make a full installation of a complete Linux distro as this is not the idea of this topic.
If you are interestet in that procedure our fellow Gerolf described it in detail, in several post about it, starting here, and please ask him all your questions related to such procedure as so far I do not have any experience in that procedure and never used Devian before.
By the way it was good when Gerolf demonstrated I was wrong when I said G4E could not be chainloaded from the grub.cfg of Devian because the secure boot chain was going to be broken, which showed me his approach works fine, and it is also a viable alternative.
EDIT: Our fellow wimb tested the previous approach and it did not work.
From this post:
I have installed openSUSE Tumbleweed on GPT partition and can boot openSUSE Linux in UEFI Secure mode.
However, chainload of UEFI Grub4dos (Grub4EFI) fails in UEFI Secure mode with the message: bad shim signature
So indeed the secure boot chain is broken as expected already by alacran
