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.

@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.
https://www.youtube.com/watch?v=6xrAqhzvSms
Merci à tous pour vos précieux conseils, ce forum est vraiment d'un grand secours.

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

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.

Re : Partition Ubuntu écrasée par Windows 10

Bonjour,
Je relance le post pour vous confirmer que l'installation des deux dernières mises à jour de Win 10 (notamment la 1809), ont provoqué la suppression de ma partition principale Ubuntu. Redémarrage sur la ligne de commande Grub rescue et plus de partition système Ubuntu !
J'ai une config en dual boot Ubuntu 18.04 / Win 10, avec plusieurs partitions (Win 10 : C:/ D:/ Documents F:/ Ghost // Ubuntu : / (principale) /home /opt).
Depuis plusieurs années je ne rencontrais aucune difficulté particulière et le dual boot fonctionnait bien (avec partage des profils firefox et thunderbird).
Lors des  deux dernières mises à jour majeures de Win 10 ma partition principale Ubuntu, formatée en Ext4, a été effacée et remplacée par une partition de rescue Win 10 cachée, formatée en NTFS, et un espace non alloué. Par chance mes autres partitions linux, formatées en Ext3, n'ont pas été touchées.
En fait, Win 10 crée une partition de restauration sur le premier espace qu'il considère comme libre, donc pour lui du Ext4 c'est libre !
La première solution que j'ai trouvée a été de réinstaller Ubuntu en reformatant l'espace non alloué. (Avec quelques installations à refaire et de petits désagréments ! Quoi-que, repartir sur du neuf de temps en temps ...)
Je n'ai pas essayé faire reconnaître l'espace non alloué comme une partition Ext4, désolé j'aurais dû, pour voir ce que l'on pouvait récupérer dans cet espace non alloué. Si Win 10 ne fait que déplacer la partition, c'est peut-être jouable.
Pour moi, seule la partition système étant concernée, la réinstallation était la solution la plus simple, sans perte de données.
Lors de la première mise à jour qui avait viré Ubuntu, j'avais laissé la partition cachée créée par Win 10 en pensant qu'il la réutiliserait pour les mises à jour suivantes.
Peine perdue, à la deuxième mise à jour il a encore effacé ma partition Ext4, en étendant un peu sa partition de rescue.
Une sauvegarde s'impose, avant toute mise à jour majeure de Win 10 qui permet un retour en arrière, car la création d'une partition rescue réorganise les partitions existantes non reconnues par windows sans discernement.
Sauf à se séparer définitivement de windows, je ne vois pas de solution ;-(( Installer Ubuntu sur du NTFS ??
Courage à tous ceux, qui comme moi, persistent dans le dual boot.

Re : Partition Ubuntu écrasée par Windows 10

Salut,

Je pense, sans certitude, qu'il y a deux moyens de prévenir le problème :

1. Installer le démarrage avancé directement sur C (ainsi la MAN ne tentera pas de créer une nouvelle partition).
2. Étendre cette fameuse partition à 1 ou 2 Go. La MAN ne sera pas entravée par un espace insuffisant.

Ou 3. Tu utilises des disques séparés pour les deux OS.

Bonjour,
J'ai déjà rencontré ce problème : https://forum.ubuntu-fr.org/viewtopic.php?id=2010052
Je te prie de faire un Boot-Info depuis une session de ton Ubuntu installé et de donner l'URL de ce Boot-Info dans ta réponse. Je pourrai vérifier s'il s'agit bien du même problème et si c'est le cas, te suggérer des moyens d'éviter que ça recommence à la prochaine mise à niveau de Windows 10.

Re : Partition Ubuntu écrasée par Windows 10

Bonjour, malbo,
Merci pour l'intérêt que tu portes à mes petits soucis.
Voici le lien du boot-info lancé depuis ma session ubuntu : http://paste.ubuntu.com/p/fg5spxnG4n/.
Je suis preneur de toute solution qui me permettrait de garder les choses en l'état lors de la prochaine mise à jour de windows.
Avant ta réponse, j'envisageais d'augmenter la taille de la partition sda3 (rescue mise à jour) après avoir réduit la sda2 (système win 10) avec le gestionnaire de disques de windows, sans toucher à la partition étendue sda 4 qui contient tout ce qui à de l'importance pour moi.
Il serait peu-être bon de pouvoir la repasser en "hidden" car je l'avais montée pour voir son contenu et je ne sais pas trop si win 10 l'utilisera en l'état pour sa prochaine mise à jour.
La supprimer en laissant un espace non alloué serait peut-être aussi une solution pour permettre à la mise à jour de windows de la recréer.
A l'origine ma distribution ubuntu était sur la partition sda3, mais le fait qu'elle soit passée sur la sda10 dans la partition étendue ne pose pas de problème. Et puis déjà trois partitions principales, sauf a supprimer la sda1 (rescue de l'ordi) que je garde un peu par nostalgie, sans trop savoir à quoi ça me servirait de restaurer en win 7 d'origine.
Le message sur le boot sector des sda5 et sda8 semble sans conséquences sur le fonctionnement.
Merci encore.

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub2 of sda10 into the MBRs of all disks (except live-disks and removable disks without OS).
Grub-efi would not be selected by default because: no-win-efi
Additional repair would be performed: unhide-bootmenu-10s


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le disque sda (ATA ST31000528AS) !

Les fichiers de démarrage de [L'OS actuellement utilisé - Ubuntu 18.04.2 LTS] sont loin du début du disque. Votre BIOS pourrait ne pas les détecter. Vous voudrez peut-être re-essayer après avoir créé une partition /boot (EXT4, >200MB, en début de disque). Cela peut être réalisé via des outils tels que gParted. Puis sélectionnez cette partition via l'option [Partition /boot séparée :] de [Boot-Repair]. (http://doc.ubuntu-fr.org/tutoriel/partition_boot)


=================== User settings
The settings chosen by the user will not act on the boot.

Le malaise est visible dans cet extrait :

=================== parted -lm:

BYT;
/dev/sda:1000GB:scsi:512:512:msdos:ATA ST31000528AS:;
1:1049kB:26.8GB:26.8GB:fat32::hidden, lba;
2:26.8GB:209GB:183GB:ntfs::boot;
3:209GB:210GB:966MB:ntfs::;
4:210GB:1000GB:790GB:::lba;
10:210GB:289GB:78.6GB:ext4::;
5:289GB:446GB:157GB:ntfs::;
6:446GB:525GB:78.6GB:ext3::;
7:525GB:577GB:52.4GB:ext3::;
8:577GB:990GB:412GB:ntfs::;
9:990GB:1000GB:10.5GB:linux-swap(v1)::;

On y voit que la partition 10 (c'est la partition racine de ton Ubuntu) n'est pas numérotée dans l'ordre du disque. En conséquence, lors d'une prochaine mise à niveau de Windows, s'il y a la moindre modifcation par Windows de la table de partition, Windows considère que la partition 10 ne peut pas se trouver avant la partition 5, donc il la supprime carrément. Il doit y avoir une possibilité d'éviter cela en renumérotant les partitions dans l'ordre du disque mais je ne maitrise pas la chose.
EDIT : j'ai trouvé cette discussion sur le sujet : https://forum.ubuntu-fr.org/viewtopic.php?id=2017407
Cela ne me semble pas limpide.

EDIT : tu peux suivre le paragraphe 3.2.5 Réparer l'ordre des numéros de partitions puis le paragraphe 3.2.6 Sauvegarder les changements de la doc FDISK. Si tu décides de te lancer dans cette tentative, je te recommande de faire auparavant une sauvegarde sur disque dur externe de tous les doc précieux que tu peux avoir dans ce disque dur. En effet, quand on touche au partitionnement, un accident est vite arrivé.

Re : Partition Ubuntu écrasée par Windows 10

Bonsoir, malbo,
Merci pour ton analyse.
J'avais bien constaté l'incohérence de la table de partition avec ubuntu sur la sda10, mais cela ne gênait pas son fonctionnement.
Et cette table de partition résultant de la réinstallation d'ubuntu je l'avais laissée.
Depuis, l'erreur c'est un peu réparée par hasard ou par accident ;-)
En effet, voulant masquer la partition de rescue win 10, j'ai utilisé l'utilitaire windows MiniTool Partition Wizad et le simple fait de masquer la partition lui a fait reconstruire une nouvelle table reconnue par windows.
Au démarrage de linux, la table ayant changé je me suis retrouvé sur le grub rescue. Un peu logique.
J'ai alors fait un boot repair "standard" après avoir lancé ubuntu sur une live USB.
Réparation impeccable et ma table de partition semble revenue à la normale, sans perte de données. Elle est visible là : http://paste.ubuntu.com/p/d2r7VnRQ5Q/
Pour faire un peu de place pour la partition de rescue win 10 j'ai lancé Disques pour réduire la partition principale windows que j'avais préalablement défragmentée sous windows.
Petite sueur froide quand après la modification Disques n'affichait plus toutes les partitions, alors qu'elles étaient fonctionnelles. Après redémarrage Disques reconnaissait à nouveau toutes les partitions avec un espace non alloué entre ma partition principale win 10 et sa partition de rescue.
Pas très confiant pour étendre la partition de rescue avec Disques, j'ai préféré utiliser Gparted déjà utilisé il y a longtemps et pas de problème.
Ma table de partition semble correcte ; la win rescue fait maintenant plus de 3GO et elle est bien passée en "hidden".
Je n'ai plus qu'à attendre la mise à jour win 10 de mai et croiser les doigts lorsque elle passera.
Encore merci.
JR

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub2 of sda5 into the MBR of sda.
Grub-efi would not be selected by default because: no-win-efi
Additional repair would be performed: unhide-bootmenu-10s


=================== Final advice in case of suggested repair


Les fichiers de démarrage de [L'OS actuellement utilisé - Ubuntu 18.04.2 LTS] sont loin du début du disque. Votre BIOS pourrait ne pas les détecter. Vous voudrez peut-être re-essayer après avoir créé une partition /boot (EXT4, >200MB, en début de disque). Cela peut être réalisé via des outils tels que gParted. Puis sélectionnez cette partition via l'option [Partition /boot séparée :] de [Boot-Repair]. (http://doc.ubuntu-fr.org/tutoriel/partition_boot)


=================== User settings
The settings chosen by the user will not act on the boot.

On peut y voir que la numérotation des partitions est dans l'ordre du disque :

BYT;
/dev/sda:1000GB:scsi:512:512:msdos:ATA ST31000528AS:;
1:1049kB:26.8GB:26.8GB:fat32::hidden, lba;
2:26.8GB:207GB:180GB:ntfs::boot;
3:207GB:210GB:3507MB:ntfs::hidden;
4:210GB:1000GB:790GB:::lba;
5:210GB:289GB:78.6GB:ext4::;
6:289GB:446GB:157GB:ntfs::;
7:446GB:525GB:78.6GB:ext3::;
8:525GB:577GB:52.4GB:ext3::;
9:577GB:990GB:412GB:ntfs::;
10:990GB:1000GB:10.5GB:linux-swap(v1)::;

Tu n'auras plus le problème de disparition de la partition racine lors de la prochaine mise à niveau de Windows 10
Par contre, je crains que tu aies un problème avec la partition 3 que tu as tripotée (tu l'as mise en "hidden"). A mon avis, il faudrait supprimer cette partition 3 (*) pour laisser l'espace non partitionné à la place. Lors de la prochaine mise à niveau de Windows 10, cette partition sera recréée automatiquement par le système de mise à niveau.

(*) pour la supprimer, je pense que le mieux est d'utiliser Gparted depuis une session live de Ubuntu. Motif : Gparted va supprimer cette partition sans renuméroter toutes les autres partitions.

Re : Partition Ubuntu écrasée par Windows 10

Bonjour,

Est-ce que je vais avoir le problème avec l'ordre de mes partitions - je suis en double boot avec Windows 10 ?

@jfbenat : la suppression de partition ne concerne que les installations faites sur partitions MSDOS. Toi tu as une table de partitions GPT donc tu n'auras pas ce problème.
