Partition Ubuntu écrasée par Windows 10

Bonjour à tous,
J'utilise Ubuntu 18.04 en dual boot avec Windows 10 et je n'utilise Windows 10 QUE pour y faire les mises à jour, c'est à dire grosso modo une fois par trimestre. Le weekend dernier, j'ai donc voulu mettre à jour Win 10 et comme cela prenait un temps qui me semblait long, très long, j'ai attendu seulement la fin de la mise à jour d'un seul programme et j'ai éteint mon ordi.
Il se trouve que maintenant, au démarrage, je n'ai plus accès à ma session Ubuntu, je démarre sur Win 10 et ma partition Ubuntu est non seulement inaccessible, mais elle a disparu.
Lors de l'installation de 18.04, j'avais attribué les 2/3 du DD à Ubuntu, le reste étant pour Windows.
Or, quand je regarde aujourd'hui les propriétés du DD sous Win 10, Windows a écrasé Ubuntu et occupe désormais les 850 Go restants.
Je ne suis pas fin connaisseur du sujet, mais il me semble que pour supprimer Ubuntu, une mise à jour de Win 10 ne suffit pas et qu'il faut d'autres interventions manuelles pour enlever la partition Ubuntu.
Comment cela peut-il arriver ? J'ai attrapé une cochonnerie sous Win 10 qui semé la pagaille sur mon DD ?
ET surtout, est-il possible de retrouver ma session Ubuntu ? (Que n'ai JAMAIS voulu supprimer bien sûr) Ou bien faut-il réinstaller 18.04 ?
Merci de vos conseils,
MARC

Bonjour

Surprenant en effet.
Vous pourriez depuis Windows, Installer Minitool partition Wizard (qui correspond à Gparted) pour vérifier l'état de votre disque.
Windows (depuis : Ce PC - Gérer - Disques -) ne voit pas les partitions Linux mais ce n'est pas pour autant qu'elles ont disparu.
Vous pourriez retrouver Grub en effectuant un "Boot repair disk". depuis un DVD

Bonjour,
Je ne crois pas qu'une mise à jour ou même une mise à niveau de Win10 puisse faire ça (occuper des Go pris à Ubuntu). Je pense que ce que tu vois dans les "propriétés du DD sous Win 10", n'est pas la réalité. Pour savoir vraiment ce qui se passe, je te prie de démarrer ton ordi sur un support Live de Ubuntu 18.04 (ou 18.04.1) afin de faire une session live (choix "Essayer Ubuntu"). Tu feras un Boot-Info depuis la session live et tu donneras l'URL de ce Boot-Info dans ta réponse.

Re : Partition Ubuntu écrasée par Windows 10

@Malbo :
Bonjour et merci pour les conseils. J'ai effectivement démarré l'ordi sur le support 18.04 et j'ai retrouvé ma session Ubuntu.
Mais pas d'accès pour "Essayer Ubuntu", j'arrive directement sur le GRUB, comme si j'allumais mon PC et avais le choix du système d'exploitation.
J'ai redémarré pour voir si j'avais à nouveau ce menu au démarrage, mais j'arrive directement sur Windows. En clair, je n'ai accès à ma session Ubuntu que par le support DVD.
Comment retrouver le menu au démarrage où j'ai le choix entre Ubuntu et Windows ?

=================== 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.

D'après ce que je vois là-dedans, ton ordi serait un HP. Peux-tu donner le nom du modèle ?

Re : Partition Ubuntu écrasée par Windows 10

Je n'arrive pas à trouver confirmation de ça pour ton modèle mais en général, il suffit de presser la touche F9 au démarrage de l'ordi pour faire apparaitre le Boot Menu dans lequel tu trouveras une entrée "ubuntu". Cela te permettra de démarrer sur le menu Grub. Il y a peut-être un moyen d'obtenir le démarrage par défaut sur le menu Grub mais essaie déjà ce que je te propose (avec la touche F9)

Re : Partition Ubuntu écrasée par Windows 10

En fait, c’est bien la mise à jour de Windows 10 qui a entraîné la disparition du GRUB.
Je ne pouvais utiliser Ubuntu qu’avec le CD au démarrage, et à ce moment-là, je retrouvais ma session.
En continuant à chercher une solution, j’ai finalement trouvé un tuto sur YouTube qui explique comment retrouver le GRUB (en ligne de commande).
Ce que j’ai fait et le GRUB est revenu au démarrage, comme avant, en me proposant le choix de l’OS à utiliser.
Pour vérifier, j’ai redémarré l’ordi et tout était redevenu normal.
Je pense ne pas être le seul à subir ces petits désagréments, alors, je mets le lien vers ce tuto, qui est très bien fait pour expliquer la manipulation.

Merci à tous pour vos précieux conseils, ce forum est vraiment d'un grand secours.

Re : Partition Ubuntu écrasée par Windows 10

Bonsoir,
Le tuto VulgaNux dont tu as donné le lien contient plusieurs méthodes. As-tu réussi en utilisant la première méthode proposée dans ce tuto (celle qui propose de presser la touche F9 au démarrage pour parvenir à démarrer sur Ubuntu ) ?

Re : Partition Ubuntu écrasée par Windows 10

Oui, j'ai utilisé la première méthode, celle qui correspondait trait pour trait à mon problème.
J'avais pris soin de visualiser la vidéo avant de commencer toutes les manipulations.

Re : Partition Ubuntu écrasée par Windows 10

Merci pour cette précision. La méthode qui a réussi pour toi est très proche de celle présentée dans le paragraphe 7. Dépannage du dual-boot avec Windows 8 ou Windows 10 de la doc UEFI
La commande "sudo grub-install /dev/sda" proposée dans le tuto VulgaNux ne sert à rien. Seule la commande "sudo grub-install" est nécessaire et suffisante.
