UEFI Boot Manager for 5.1
« on: May 17, 2022, 01:07:15 am »
Is AN going to provide a UEFI capable boot manager with the upcoming 5.1 release?  While one of my ArcaOS/Linux computers will continue using GRUB 2, I have another computer where I would like to boot into two different GUID ArcaOS system partitions.

Yes, it is the plan. Can always use other boot managers such as rEFIND.

Being on the testteam of Arca Noae for ArcaOS 5.1. and seen Alex Taylor his presentation off ArcOS 5.1. I can say the following.
You can install ArcaOS on an MBR disk layout with UEFI boot. But this is approach has a lot technicall drawbacks. MBR I consider dead with all the limitations. It has GPT support and any dual boot with Windows 10/11 will require GPT support because WIndows 10, when installed on system booted in UEFI mode, Windows will only accept GPT disc layout.  If you have a current installation with Windows 10/7 with an MBR disc layout that can remain in that way.

With the arrival of GPT support a lot of old problems are wiped out for OS/2 users finally. And one of them is that you can basically use any disc editor on hard drive or any boot manager. And a bootmanager on UEFI is nothing special. Its  a menu that tells which OS you want to start. This means that old issue's with bootmanager no longer apply. No more primary partition needed and Airboot is also gone.

On a GPT hard drive you have a so called ESP partition. Every partition has its on so called GUID ID, which means that each partition has its own type. The ESP partition is a special type and ArcaOS or Windows puts its EFI file on this partition.  And via a UEFI bootmanager you select simply which EFI file gets loaded.  The AN bootmanager is called AN launcher.

Hi

I have a related doubt here. From what I understand on GPT partitioned HDD, AiR-BOOT will no longer work. AiR-BOOT is only for MBR, right? or did I get it wrong?

You are correct. Air Boot does not work with GPT. It is one of the things that needs to be replaced by a different boot manager.

AIRBoot also depends on the BIOS (CSM) to be present on an MBR boot with UEFI airboot will also not work. I am also not certain how well MBR/UEFI boot is supported by other operating systems.
