Bonjour.
@geole.
La machine en UEFI est un Dell LatitudeE4310.
Je peux paramétrer le Bios pour qu'elle démarre par défaut en Bios_Legacy, ou en UEFI.
Dans tous les cas çà démarre sur l'USB si un périphérique USB bootable est branché.
Elle est paramétrée pour démarrer par défaut en Bios_Legacy, vu que les install sur le SSD interne sont en Bios_Legacy.
Au démarrage, avec la touche F12, j'accède à un menu qui permet de choisir un mode de démarrage temporaire autre que par défaut.
Comme j'ai testé des installations sur clé USB (UEFI/Bios_Legacy) de tests, table de partition GPT. Dans le mode de démarrage en UEFI, il y a proposé; "Ubuntu" entrée qui correspond à la clé de tests depuis çà céation et son premier démarrage en UEFI.
Si elle est branché çà démarre en UEFI, sinon, çà renvoie en Bios_Legacy pour démarrer sur le SSD interne.
Si je branche d'autres clé USB capables de démarrer en mode UEFI, en plus de "Ubuntu", il y a une entrée pour le périphérique USB clé branchée. Donc je ne peux pas confondre avec l'entrée de la clé de tests " Ubuntu".
Lorsque je branche la clé Ventoy, elle est proposée dans le mode de démarrage Bios_Legacy uniquement.
Lorsque je branche une clé usb boutant sur l'UEFI, elle est proposée dans le mode UEFI.
Les clés MultiSystem démarrant sur les deux modes, elles sont proposées au démarrage dans les deux modes.
La clé de tests qui démarre dans les deux modes est proposée aussi au démarrage dans le mode Bios_Legacy.
Donc c'est ce qui me permet de confirmer qu'il y a un souci de démarrage en mode UEFI avec la clé Ventoy.
Comme toi, je soupçonne le format de la partition boot-efi en FAT16 de cette clé. Ma machine ne pouvant certainement pas démarrer dessus en UEFI.
Peut-être qu'en créant une partition boot-efi (boot-esp) en FAT32, et en y copiant dedans le contenu de la partition boot-esp FAT16, çà va marcher?.
Je vais faire un boot-info avec cette clé branchée pour voir le contenu de tout çà...
Boot-info fait machine démarrée en Bios_Legacy;

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub2 of
sda2 into the MBRs of all disks (except live-disks and removable disks without OS).
Grub-efi would not be selected by default because: legacy-win no-win-efi
Additional repair would be performed: unhide-bootmenu-10s
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your BIOS boot on sda (ATA LDLC) disk!
Je vais refaire la même chose, machine démarrée en session live UEFI (clé MultiSystem) .
La partition /dev/sdb1 est le MultiSystem.

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub2 of
sda2 into the MBRs of all disks (except live-disks and removable disks without OS).
Grub-efi would not be selected by default because: legacy-win no-win-efi
Additional repair would be performed: unhide-bootmenu-10s
Confirmation request before suggested repair: __________________________________
LegacyWindows detected. The boot of your PC is in EFI mode. You may want to retry after changing it to BIOS-compatibility/CSM/Legacy mode.
Are you sure you want to continue anyway?
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your BIOS boot on sda (ATA LDLC) disk!
Please set your BIOS in Legacy mode in order to start your Ubuntu 20.04 LTS, then type command [sudo update-grub] in order to add the Windows entry to your GRUB menu.
