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: __________________________________________
/target detected. Please reboot and try again from a new live session.
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your UEFI firmware boot on sda1/efi/****/shim****.efi (**** will be updated in the final message) file!
J'ai du mal à comprendre la situation. EDIT : je crois y voir plus clair : le Boot-info a été fait depuis une session-live démarrée sur le disque externe "WD My Passport 259D" de 2 To. D'habitude, on utilise une clé USB comme support d'installation (une Live USB) et là un disque dur de 2 To comme support d'installation, c'est surprenant. Ce que tu appelles ton "disque dur interne" est en réalité un SSD de 128 Go dont la référence est SanDisk SD8SN8U (cette référence est visible dans cette doc "SanDisk X400 SSD", en page 2)
Je te prie de préciser le nom complet de ton modèle d'ordi.
