Boot impossible après mise à jour Windows (ACER Aspire XC-780)

Bonjour,
J'utilise Ubuntu 18 en dual-boot avec Windows10 sur un PC ACER Aspire XC-780 depuis quelque temps déjà, et j'en étais satisfait jusque là.

Mais après une grosse mise à jour de Windows, voici ce qui m'est arrivé :
Comme c'est déjà arrivé par le passé, au moment de précédentes grosses mises à jour Windows, le PC ne bootait plus que sur Windows. Il y avait une petite manip à faire via la fenêtre de commande de Windows pour résoudre le problème, en mode admin de Windows :

bcdedit /set {bootmgr} path \EFI\ubuntu\shimx64.efi

Mais cette fois, impossible de booter le PC : au démarrage j'ai le message :

Reboot and Select Proper Boot Device
or Insert Boot Media in selected device and press a key

En rebootant et en affichant le menu de boot, il ne propose effectivement que le Windows Boot Manager, que j'ai bien peur d'avoir fait planter avec ma manip bcdedit du dessus qui marchait bien jusqu'alors, car au lieu de lancer Windows il m'affiche le message ci-dessus...
En insérant une clé USB bootable sur Ubuntu je peux booter dessus, mais ce n'est que provisoire...

J'ai bien peur d'avoir fait une fausse manip, mais j'aimerais utiliser vos lumières pour retrouver un dual-boot "propre"

Ci-dessous mon URL Boot info (obtenue à partir de la session bootée sur clé USB, car sinon impossible d'obtenir quoi que ce soit...)

Merci d'avance de votre aide
Cordialement,
ML

Bonjour,

En passant par le bios toujours la même erreur? Secure Boot activé ou désactivé?

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sda6, using the following options:        sda1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot use-standard-efi-file


=================== Advice in case of suggested repair
Veuillez désactiver SecureBoot dans le BIOS. Puis réessayez.Voulez-vous continuer ?


=================== 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 !

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.

Re : Boot impossible après mise à jour Windows (ACER Aspire XC-780)

Bonsoir.
Si windows ne peut plus booter, il faut que tu lances le support d'installation de windows pour réparer....
Je pense que la cause fut une faute de frappe dans cette  expression    "  \EFI\ubuntu\shimx64.efi   "
car le fichier existe bien

sda1: __________________________________________________________________________
    File system:       vfat

Bonjour,

En passant par le bios toujours la même erreur? Secure Boot activé ou désactivé?

Ben le truc c'est que j'arrive pas non plus à ouvrir le BIOS, il me renvoie sur le meme message d'erreur (reboot and select...), je peux seulement accéder au menu de boot

Bon j'ai carrément sauté le pas, j'ai réinstallé Ubuntu seul sans Windows et ça marche bien tongue tongue
