I would like to know how to use Gnome Boxes in order to install VM in UEFI mode ?
Indeed, whatever iso i use to create a virtual machine : arch, manjaro, endeavous os, solus etc…
They all start with Seabios, thus in BIOS (MBR) mode. There are a lot of similar issues on forums/reddit, but i cannot find any solution.
Some say i have to install edk2-ovmf, but it’s already installed.
According to this issue reported on Gnome gitlab, it should be possible out of the box
I don’t know why you expect a GPT option - GPT is the partition table structure - just continue with the default for the loader - it is what the unformatted partition is used for.
Gnome Boxes is an extremely limited solution that is built to be a “single click” solution. It is super easy to use but offers almost no flexibility.
One trick that people sometimes use is to use virt-manager to modify the VMs that are created by gnome boxes. This works because both solutions are just different front-ends for libvirtd.
I do not know either to be honest, just because i have choosen the GPT partition table (on the first screenshot) and not MBR, i thought i would see it on the last screenshot to install the bootloader on.
Seeing MBR instead is confusing to me.
