Dernier message de la page précédente :

Pourtant il est installé déjà, mais on ne peut pas le réinstaller, probablement la cause de tes soucis.

Que donne le retour de cette commande

Code : Tout sélectionner

sudo ls -la /boot/efi/EFI/

J'anticipe ta prochaine question :

drwxr-xr-x 3 root root 4096 Mar  1 21:25 .

Bien joué pour l'anticipation
tout m'a l'air en ordre, alors tu vas maintenant me faire ça, on va oublier le paquet grub-efi-amd64-signed qui nous emm*****

Code : Tout sélectionner

sudo apt install grub-efi grub-efi-amd64 grub-efi-amd64-bin secureboot-db

Et ensuite on tentera une simulation pour virer un paquet voir ce que ça donne.
Et si rien ne va, vu que t'es sur ta live usb de mint, on pourra utiliser boot-repair (même si je n'apprécie pas ce logiciel)

le paquet grub-efi-amd64-signed est cassé à mon avis, donc on va tenter un truc, pas sur que la commande passe (à mon avis il y aura une erreur)

Code : Tout sélectionner

sudo dpkg --configure grub-efi-amd64-signed

Donne moi bien le retour du terminal en cas d'erreur.

il est coriace celui-là, alors on va tenter quelque chose.
Là on fait de la simulation, donc copie colle bien mes commandes, sinon ça va virer à la catastrophe....

Tu me donnes le retour de cette commande

Code : Tout sélectionner

sudo apt autoremove --purge -s grub*

Le retour du terminal va être un peu long, c'est normal.
