UEFI Build requests - suggested help

[m654321]

(1)  While I understand that LL isn't now adapted for UEFI and I understand that I can (I assume) switch to Legacy mode,
      what I don't understand is what that will affect.
(2) What does UEFI do that BIOS doesn't (and vice versa)?
    (Yes.  I've done a search and don't see anything that I can easily understand.)

I'm really glad you asked these questions, as the whole area of UEFI is hazy for me (& many others too)  :-\
This is despite having personally set-up a tutorial for a UEFI dual-boot for LL2.x / Windows OS - the core of it is based largely on Nehal J Wani's work with my own detailed comments and observations added: https://www.linuxliteos.com/forums/tutor...y-enabled/

I'll share some of my "UEFI experiences" with you (below) - LOL, it sounds like alien encounters - that I had while experimenting with setups on a UEFI laptop, an Asus G750JS - see setup[1] in footnote below.

I was only able to install distros in Legacy/CSM mode (UEFI & Secure Boot disabled), if I used an HDD, where the use of a DOS (MBR) formatted disk is implicit.  Installation on an SSD in Legacy/CSM mode (again MBR format implicit) didn't work as, each time I tried this, I'd get a red notification about a "wrong signature key" or something of that sort. It seemed that when I used an SSD for an install, the laptop expected a GPT format not an MBR one.  Consequently, I can only run SSDs on the Asus G750 for UEFI set-ups only. I don't know if this SSD behaviour is typical of other UEFI computers, as I wasn't able to find any mention of it on the internet ...


Of course, I didn't want to go back to using HDDs after having tasted the performance boost with SSDs, so I changed to a UEFI supported distro in setup[1] - I'm now using Manjaro 17 on this laptop, though it is with much regret I'm unable to use LL on it. Like quite a few LL users on the forum, I'd warmly welcome an official UEFI release of LL, so that it could be used on newer computers. However, it's unclear whether Jerry is able to continue with the UEFI project, owing to the obvious constraints of time & energy involved in that ...
