=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sda4, using the following options: sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s fix-windows-boot use-standard-efi-file restore-efi-backups
=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le fichier sda1/efi/.../grub*.efi !
Vous souhaiterez peut-être aussi installer Refind. (https://help.ubuntu.com/community/ubuntupreciseon2011imac)
Si votre ordinateur redémarre directement sur Windows, essayez de changer l'ordre de démarrage dans votre BIOS.
Si votre BIOS ne permet pas de changer l'ordre de démarrage, changez l'entrée de démarrage par défaut de l'amorceur Windows.
Par exemple, vous pouvez démarrer Windows, puis saisir la commande suivante dans une invite de commande en mode administrateur :
bcdedit /set {bootmgr} path \EFI\...\grub*.efi
=================== User settings
The settings chosen by the user will not act on the boot.
On constate que le problème est bien uniquement un problème de démarrage. Le responsable de cette cagade, c'est le fabricant HP qui verrouille le démarrage du "Bios" Je ne sais pas trop ce qu'il faudrait faire...
EDIT : on va quand même tenter quelque chose : depuis une session de ton Ubuntu démarré en passant par la LiveUSB Super Grub2 Disk, tu passeras la commande suivante :
sudo grub-install
Tu donneras le retour complet (*) de cette commande. Puis tu passeras cette autre commande :
sudo efibootmgr -v
Et tu donneras également le retour complet (*) de cette commande.
(*) la définition du retour complet est donnée par cqfd93 dans ce post :
