Probable écrasement d'Ubuntu par Windows 10
Bonjour à tous,
Je me tâtais désespérément à ouvrir un sujet pour évoquer mon cas, puis finalement je me lance :-)
Comme évoqué ici, j'avais un dual boot Ubuntu/Windows7 et mon ordi a probablement fait l'upgrade vers W10 pendant sa veille (la nuit). Je m'en suis rendu compte le matin devant l'écran noir de l'ordi.
J'ai du reboot. Désormais, j'ai simplement le premier écran au démarrage, qui boucle 3 fois puis passe sur le BIOS. (pas de grub rescue).
Pour comprendre ce qu'il se passait, j'ai installé Ubuntu sur une clé USB, puis j'ai démarré la version d'essai sur l'ordinateur.
Par la suite : le disque dur où se situaient les OS est un SSD de 256Go et est identifié comme étant le sda dans le système. sdb correspond à un HDD avec simplement des données dessus et sdc est la clé USB sur laquelle Ubuntu est lancé.
J'ai lancé Gparted. Il affiche le warning suivant puis voit le disque sda mais aucune partition. J'ai simplement un unallocated 238,47GiB.
Warning :
The driver descriptor says the physical block size is 2048 bytes, but Linux says it is 256 bytes.La commande fdisk ne m'indique pas grand chose de nouveau (?) :

=================== Suggested repair
The default repair of the Boot-Repair utility would not act on the MBR.
The boot flag would be placed on sdc2.
Additional repair would be performed: repair-filesystems
=================== User settings
The settings chosen by the user will not act on the boot.Puis j'ai lancé testdisk. Il ne détecte aucune partition et ne répare pas automatiquement ma table de partitions. J'ai par conséquent simplement le disque sda qui est détecté, sur lequel il n'existe plus de table de partition. Le quick search et le deep search ne donnent rien. On m'a conseillé d'y aller à tâtons en créant manuellement une table de partition et en montant le volume...
Si vos lanternes pouvaient m'éclairer un peu ce serait super, je me sens un peu démuni.
Merci par avance,
Bien à vous,

Re : Probable écrasement d'Ubuntu par Windows 10
Salut,
Le mbr du disque /dev/sda est pourri, ce qui est étonnant c'est que l'installation initiale de ce pc semble avoir été en mode uefi donc ce disque devrait héberger une table de partitions GPT qui est localisée en dehors de ce mbr.
Ce qui me fait penser cela c'est que le disque /dev/sdb abrite une table de partitions GPT, Boot-info est lancé en mode UEFI.
===> le mbr de protection de la table de partitions GPT (table de partitions MSDOS ne comportant habituellement qu'une partition primaire étendue sur tout le disque) ne joue plus son rôle.
Comment as-tu lancé testdisk?
As-tu choisi dans le menu sélection de la table de partitions EFI/GPT?
Autre piste utiliser l'outil de partitionnempent GPT gdisk.
sudo gdisk /dev/sdaCelui-ci devrait pouvoir dire d'entrée si le disque héberge une table de partitions GPT et te proposer de recréer un mbr de protection GPT.
Donne-nous les retours de ces commandes, pour quitter gdisk sans maj de la table de partitions taper q comme quit.

Re : Probable écrasement d'Ubuntu par Windows 10
Je vois que gpart a été utilisé, je ne connais pas cet outil, d'après sa page man, il faut prendre ses résultats avec précaution suivant ces deux extraits:
It should be stressed that gpart does a very heuristic job, never believe its output without any plausability checks. It can be easily right in its guesswork but it
can also be terribly wrong. You have been warned.et
BUGS
gpart is beta software, so expect buggy behaviour.Dernière modification par maxire (Le 13/07/2016, à 09:40)

Re : Probable écrasement d'Ubuntu par Windows 10
Bonjour,
tout d'abord merci pour vos réponses.

J'ai essayé ces deux options :
[Intel ] Intel/PC partition
[EFI GPT] EFI GPT partition map (Mac i386, some x86_64...)Sur chacune j'ai ensuite fait
Analyse > Quick Search > Deeper searchJ'ai essayé de changer la geometry de mon disque en modifiant le Sector size de 512 à 2048 bits, puis relancé la quick et la deeper search, sans résultat. J'ai ensuite réinitialisé le sector size à sa valeur initiale 512.
Résultat de la commande gdisk
sudo gdisk /dev/sda

C'est malheureusement effectivement le cas. Les documents sur Windows ont été globalement préservés car j'avais une sauvegarde mensuelle faite sur le 2ème disque (/dev/sdb). Pour le reste sous linux, j'ai quelques sauvegardes mais peu sont récentes et beaucoup de choses importantes sont perdues. Merci pour l"outil, j'essaierai cela en dernier recours

Re : Probable écrasement d'Ubuntu par Windows 10
Comme tu as bien analysé le disque avec testdisk en prenant l'option EFI/GPT et que Gdisk ne trouve pas de table de partitions GPT, je crains que c'est fichu pour une réparation via Gdisk ou testdisk.
Je n'ose pas proposer d'appliquer la proposition de Gdisk de convertir la table mbr (erronée?) en table GPT.
Cependant tu peux toujours examiner ce que Gdisk propose comme conversion et ne pas la valider.
Combien de partitions le disque /dev/sda comportait-il?

De mémoire j'avais une partition Windows puis une Linux sur / et un swap (boot-repair et gpart m'en suggère quatre mais je ne vois pas quoi. Je ne me souviens pas avoir séparer mon /home ou mon /boot de / ... après dans le doute...).
Pour Gdisk, je ne sais pas vraiment si je dois foncer ou pas. Par défaut il passe en GPT, mais ne trouve ensuite pas de partitions, la vérification de disque ne trouve aucune erreur et m'indique 238Go de libre. Et après je n'ose m'aventurer sans expertise.
Y'a t'il des outils pour tenter de récupérer des fichiers dans la masse ? Genre photorec ?

Re : Probable écrasement d'Ubuntu par Windows 10
Bon, maintenant je suis comme Malbo, si gdisk ne propose rien de viable, je pense que le mieux est de se rapprocher d'un spécialiste.
Photorec est un outil puissant à condition de bien le dominer avec ses multiples options.

Re : Probable écrasement d'Ubuntu par Windows 10
Bonjour.
Pourtant photorec que tu as installé en même temps que testdisk me semble 10 fois plus simple à utiliser. La difficulté est de mettre des noms de fichiers "parlant" et de disposer d'un espace de disque important sur un autre support.
