Au demarrage Default boot device Missing or boot failed

Bonjour à tous,
J'utilise Ubuntu depuis plus de 10 ans !
J'ai un Acer Aspire ES 15
Suite au passage à Ubuntu 22.04, au démarrage j'ai "Default Boot Device Missing or Boot Failed" qui s'affiche

1/ J'ai réussi à Booter sur ma clé Usb Ubuntu
2/ J'ai fait un boot-repair, voici le rapport, sous la discussion
3/ J'aurai besoin d'aide pour aplliquer la réparation suggérée. J'ai cherché sur les tutos mais ne trouve pas !
Un grand merci par avance

Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would reinstall the grub-efi of
sda2,
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 Ubuntu 22.04.2 LTS entry (sdc1/efi/****/grub****.efi (**** will be updated in the final message) file) !

Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would reinstall the grub-efi of
sda2,
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 Ubuntu 22.04.2 LTS entry (sdc1/efi/****/grub****.efi (**** will be updated in the final message) file) !

Le modèle est-il mentionné dans la liste_portables_acer

Re : Au demarrage Default boot device Missing or boot failed

Bonjour
Pourquoi la partition de boot SDA1 en fat32 avec drapeau ESP a-t-elle disparu?

Il faut la recréer avec gparted et lancer la réparation recommandée.
