[Résolu] Allure d'une LiveUSB réalisée avec dd

Je mentionne "Résolu" dans le titre pour ne pas qu'on vienne m'aider à créer une LiveUSB. Je n'ai pas besoin d'aide.
Je précise que "réalisée avec dd" dans le titre, ça veut dire réalisée en suivant la procédure du paragraphe En ligne de commandes du chapitre 5. Création d'un live-USB depuis Ubuntu de la doc.
Ce post est créé pour servir à identifier une LiveUSB de Ubuntu créée par cette méthode . Je n'ai pas fait la vérification mais je crois qu'une liveUSB réalisée avec USB Creator donne la même allure.

1) LiveUSB contenant Ubuntu 18.04 64 bits
Extraits du Boot-Info réalisé depuis la session live :
Dans la partie "Drive/Partition Info" :

La "signature" selon moi, c'est  "4,672  ef EFI (FAT-12/16/32)"

La signature "4,864  ef EFI (FAT-12/16/32)" de cette version 16.04.2 ne ressemble à aucune des 4 autres que j'ai identifiées dans ce post.

La signature "4,672  ef EFI (FAT-12/16/32)" de cette version 16.04.3 est identique à celle de la version 18.04. Pourquoi, comment ? Ce n'est pas du tout clair pour moi.
-------------------------------------------------------------------------------------------------
EDIT : si je colle ce qui suit dans le champ de recherche de google :

"4,672  ef EFI (FAT-12/16/32)" site:forum.ubuntu-fr.org

Parmi les résultats de recherche, je trouve :
- ce post qui correspond à une session live de Ubuntu 18.04 64 bits puisqu'on peut y voir "boot-repair is executed in live-session (Ubuntu 18.04 LTS, bionic, Ubuntu, x86_64)"
- ce post qui correspond à une session live de Ubuntu 16.04.3 64 bits puisqu'on peut y voir "boot-info is executed in live-session (Ubuntu 16.04.3 LTS, xenial, Ubuntu, x86_64)"

Dans la partie "ADDITIONAL INFORMATION", on voit bien qu'il s'agit de 16.04.4 :

boot-info is executed in live-session (Ubuntu 16.04.4 LTS, xenial, Ubuntu, x86_64)

EN CONCLUSION :
Ce que je considérais comme une signature avant de me lancer dans les manips de ce post n'est pas un signature fiable. Elle ne permet pas d'identifier une version bien définie de Ubuntu. Par exemple, Ubuntu 18.04 64 bits et Ubuntu 16.04.3 64 bits ont la même signature ( "4,672  ef EFI (FAT-12/16/32)" ). Je crois que j'ai perdu mon temps.

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sda2, using the following options:        sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s    use-standard-efi-file


=================== Blockers in case of suggested repair
Please use this software in a live-session (live-CD or live-USB). This will enable this feature.


=================== Final advice in case of suggested repair
Please do not forget to make your BIOS boot on sda1/efi/.../grub*.efi file!


=================== User settings
The settings chosen by the user will not act on the boot.

- Dans la partie "ADDITIONAL INFORMATION" (voir EDIT) :

boot-info is executed in installed-session (Ubuntu 19.10, eoan, Ubuntu, x86_64)

C'est abracadabrantesque : Boot-info indique "in installed-session" alors que c'est une session live.

et plus bas (voir EDIT) :

=================== os-prober:
/dev/:The OS now in use - Ubuntu 19.10 CurrentSession:linux
/dev/sda2:Ubuntu 19.04 (19.04):Ubuntu:linux

EDIT : j'aurais bien aimé que ce genre de connerie soit une spécificité de l'utilisation de dd. Malheureusement, ce n'est pas le cas : j'ai fait une LiveUSB avec UNetbootin et je retrouve "in installed-session" dans le Boot-info ainsi que "/dev/:The OS now in use - Ubuntu 19.10 CurrentSession:linux"
