J'ai réussi à redémarrer (je ne sais pas trop comment).
J'ai refait un 'boot-info'. Voici le résultat :
boot-info-4ppa125 [20201012_1813]

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
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on the L'OS actuellement utilisé - Ubuntu 20.04.1 LTS CurrentSession entry (sda1/efi/****/shim****.efi (**** will be updated in the final message) file) !
Dans le recovery mode, il y a la possibilité de faire "grub – Mettre à jour le chargeur d'amorçage GRUB" (voir image ici :
https://cjoint.com/c/JJmqzyWsKBv). Est-ce que c'est quelque chose que je devrais essayer ?
Merci beaucoup pour votre aide ! 🙂
