Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of
sdc2,
using the following options: sdc1/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 (sdc1/efi/****/shim****.efi (**** will be updated in the final message) file) !
Cette partie indique que le démarrage s'est fait en "recovery mode" (mode de dépannage) :
============================ Architecture/Host Info ============================
CPU architecture: 64-bit
BOOT_IMAGE of the installed session in use:
/boot/vmlinuz-5.4.0-58-generic root=UUID=7f0dd8f4-9030-48ae-aece-4aec7d7d5318 ro recovery nomodeset dis_ucode_ldr
Ce sont les mentions "recovery nomodeset dis_ucode_ldr" qui permettent d'identifier le mode de dépannage.
EDIT : je te conseille de forcer l'affichage du menu Grub au démarrage en procédant comme indiqué dans le paragraphe
4. Utilisation du menu dans cet extrait :
----------------------------------------------------------------------------------------------
On peut aussi forcer l'affichage du menu Grub : pour cela, il faut
éditer le fichier /etc/default/grub
avec les droits d'administration pour faire les modifications suivantes :
GRUB_TIMEOUT_STYLE=menu (au lieu de "hidden") et
GRUB_TIMEOUT=10 (au lieu de 0) puis en faisant la mise à jour de grub par la commande "sudo update-grub".
----------------------------------------------------------------------------------------------
Je te propose ça parce que tu crains de retrouver des ennuis au prochain démarrage : cette modif te permettra de sélectionner plus facilement le mode de dépannage.
