UEFI Build Test
WytWun:
Came across this blog post which may help some people understand how UEFI differs from BIOS/MBR.
Jerry:
"Speaking at UEFI Plugfest, a hardware interoperability testing event held by the Unified Extensible Firmware Interface (UEFI) Forum earlier this month, Intel announced that by 2020 it was going to phase out the last remaining relics of the PC BIOS by 2020, marking the full transition to UEFI firmware."
The Gods have spoken.

I got a couple new Acer laptops recently. Neither has CSM/legacy bios. First grub, then systemd. Now this. The seventh seal has been broken. Darkness everywhere.

Ikr!

I would like to hear from folks who can test this install with both UEFI & Secure Boot enabled on any machine (no VM tests please).

I can certainly try to give this a test on the Kangaroo...
- Been meaning to upgrade the boys to 4.2 might as well do a second :)

I'm pleased to be able to feedback that I've just finished installing the UEFI-enabled version on my desktop which has a 2013 Gigabyte MB and UEFI/BIOS firmware (Model Name is H61M USB3V). It took ages but solely because the UEFI interface was so uninformative about what it required and how different sections linked. Several times I was left with a system that was stuck at the POST stage and very often connected disks were reported as empty ports. Eventually it made some sort of sense and I was able to deploy the UEFI Linux Lite ISO with confidence and success.
I have 2 bootable disks and 1 other data disk in the case. On 1 disk I have installed Wxxxx10 on (and booted to it eventually before installing LL) and on another - SSD - I have installed Linux Lite. I had to use the 'Something Else' option to configure the disk to achieve this but other than that there were no difficulties.
My settings were Operating System Windows 8 (yes, even for Linux Lite) with CSM enabled and SecureBoot set to Standard Mode. I am blown away that your UEFI ISO coped with all these settings - and without a hitch.
Interestingly, although the UEFI setup I eventually used deploys CSM and SecureBoot the UEFI ISO also worked if I did not have SecureBoot deployed but then it installed a MBR type of disk partition rather than GPT, making it impossible, with this firmware at least, to dual-boot with Windows without messing about with UEFI settings, not an arrangement I looked for.
The only complication I have just now is that I seem to have lost the ability to boot to the W10 disk, dropping out to Grub Rescue. I am hopeful that Boot Repair will deal with this but if not I shall have to try to edit manually some EFI partition entries - fingers crossed.
So, really there were no LL-related issues for this installation and the upgrade to 4.8 went very smoothly too.
I can understand Jerry's antipathy to UEFI - my firmware interface is horrible to use - but it's only a matter of time before the Legacy option disappears from UEFI (scheduled for next year I think I read) and the need for a UEFI-based installation will become ever more pressing, so I hope the LL team will feel able to bite the bullet and develop new versions, building on the success of the 4.2 ISO.
