Impossible de retourner sur W10 après avoir installé un Dual Boot

Salut !

Ayant eu envie de tester Ubuntu, je me suis lancé dans l'installation d'Ubuntu 18.04 LTS en Dual Boot avec mon Windows 10 d'origine.
Cependant, ayant eu envie, il y a quelques heures, de retourner sur W10, je redémarre mon pc tranquillement, j'arrive sur le grub, je clique sur Windows, et là, ça me lance l'assistance de réparation Windows.
Je me dis que ce n'est pas très grave, cependant, quand je tente de réparer, ça me dit que c'est impossible.
Je tente de réinitialiser sans suppression des fichiers personnels, impossible.
Je tente de réinitialiser complètement, impossible.
Plus rien ne fonctionne hmm
J'ai passé quelques heures à chercher peut-être LA réponse qui sera la solution à mon problème, à bidouiller avec la console de réparation Windows etc.., mais rien ne fonctionne.
J'ai fait un boot-info, je vous donne le lien :
http://paste.ubuntu.com/p/HcwyNjNCZy/

En espérant que vous saurez m'aider.
Cordialement

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sdb5, using the following options:        sdb1/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s    use-standard-efi-file


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le fichier sdb1/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.

Ubuntu démarre t'il toujours?
As tu des données à récupérer sur Windows10?
C'est comme si le début de la partition sdb3 avait été écrasé (enfin si la MFT (master file table) se trouve bien en début de partition)

Peux tu expliquer comment tu as installé ubuntu étape par étape? (paramètres bios changés, partitions rétrécies, ....)

Re : Impossible de retourner sur W10 après avoir installé un Dual Boot

Bonjour,
Ce serait utile que tu donnes le nom complet du modèle de ton ordi et son fabricant.

Re : Impossible de retourner sur W10 après avoir installé un Dual Boot

Salut,

Perso, la seule chose que je voie, c'est ce tout petit espace vide de 1 Mo entre deux partitions, mais c'est quelque chose de fréquent :

/dev/sdb3               567,296   199,414,239   198,846,944 Data partition (Windows/Linux)
/dev/sdb5           199,415,808   248,430,591    49,014,784 Data partition (Linux)

Pour le reste, toute l'installation semble normale. Il faudrait savoir comment Windows "voit les choses" : et pour cela, il faut passer par l'assistance de réparation de Windows, invite de commandes et donner le retour de :

diskpart
list disk
list vol
sel disk 0
list part
sel disk 1
list part
exit

Bonjour
Par quelle méthode avais-tu rétrécis la partition C: de windows10?


Pour naziel, le boot-info indique
boot-info is executed in installed-session (Ubuntu 18.04.3 LTS, bionic, Ubuntu, x86_64)
