============================== Boot Info Summary ===============================
=> No boot loader is installed in the MBR of /dev/mmcblk0.
=> Grub2 (v2.00) is installed in the MBR of /dev/nvme0n1 and looks at sector
1 of the same hard drive for core.img. core.img is at this location and
looks for (,msdos5)/boot/grub. It also embeds following components:

=============================== Suggested repair ===============================
The default repair of the Boot-Repair utility would reinstall the grub2 of nvme0n1p5 into the MBRs of all disks (except live-disks and removable disks without OS).
Grub-efi would not be selected by default because: no-win-efi
Additional repair would be performed: unhide-bootmenu-10s
=================== Final advice in case of suggested repair ===================
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le disque nvme0n1 (KXG50ZNV256G NVMe TOSHIBA 256GB) !
================================= User settings ================================
The settings chosen by the user will not act on the boot.

Bien qu'il y ait une partition EFI, il s'agit d'une installation en mode Legacy (non-EFI) comme on peut le voir dans cet extrait :
=============================== UEFI/Legacy mode ===============================
This installed-session is not in EFI-mode.

On peut le voir aussi dans cet extrait (présence de grub-pc alors que grub-efi est absent) :
=============================== PARTITIONS (1/3) ===============================
nvme0n1p5 : nvme0n1, not-sepboot, grubenv-ok grub2, grub-pc ,
Je ne sais pas comment la partition EFI est arrivée là-dedans mais d'après moi elle ne sert à rien dans le fonctionnement actuel.
