Partition ubuntu et data disparu aprés migration forcée de windows 10
Bonsoir ou plutôt bonne nuit,
J'ai eu la bonne surprise au redémarrage de ma machine de me voir contraint d'installer la dernière version de Microsoft (w10).
Après que windows est fini de faire la mise à niveau, je me retrouve dans le grub rescue avec l'impossibilité de retrouver la partition linux ou le grub était installé.
ls (hd0, msdosX)/
unknow filesystem.Je reboot donc sur un live USB Boot-repair, je lance le réparage du boot (réparation recommandée).
Depuis impossible de retrouver ma partition de données en NTFS ni mes partions Ubuntu, je n'ai aucun grub d'installé et le mbr boot automatiquement sur Windows ....

=================== Suggested repair
The default repair of the Boot-Repair utility would restore the [(generic mbr)] MBR in sda, and make it boot on sda1.
Additional repair would be performed: unhide-bootmenu-10s fix-windows-boot
=================== User settings
The settings chosen by the user will not act on the boot.Je précise que :
/dev/sda1 est la prtition ou le Boot-repair a installé le boot windows
/dev/sda2 est la partition de l'OS windows
/dev/sda4 est ma partition de données normalement formatée en NTFS de 300 GO (gparted me retourne une erreur "Unable to detect file system!".
/dev/sda3 est ma partiion étendue
-> /dev/sda5 est ma partion / ubuntu (probablement)
-> /dev/sda6 est ma partiton /home ubuntu (probablement)
Bref, impossible d'accéder a ma partition de données et impossible d'installer un grub puisqu'aucune ma partition linux n'est plus reconnue .... Que dois-je faire pour restaurer mes partitions ?
J'ai trouvé un début de réponse ici >> http://askubuntu.com/questions/665445/u … -partition
Mais j'avoue que je suis un peu dépassé par les réponses fournies et que je n'y comprends pas grand chose.
Votre aide me serait d'un grand secours,
Merci .

Re : Partition ubuntu et data disparu aprés migration forcée de windows 10
Salut mewyn
Je pense que tu devrais plutôt réinstaller le GRUB avec BootRepair en session LiveCD 
De cette manière, le GRUB détectera ta partition Windows et celle de Linux alors que le MBR se cantonne à ne détecter que la partition Windows.
La réponse du lien que tu as posté va dans le même sens.

Re : Partition ubuntu et data disparu aprés migration forcée de windows 10
Salut Li@nel,
J'ai mis à jour mon post en y ajoutant des informations supplémentaires. Boot-repair ne me propose pas de réinstaller le GRUB (étant donner qu'il ne trouve de partition Linux), il me propose seulement de restaurer le mbr pour me permettre de booter sur Windows ..

Re : Partition ubuntu et data disparu aprés migration forcée de windows 10
Je suis au bord de la panique.
J'ai tout essayé et impossible de récupérer ma partition /dev/sda4 NTFS (ou il y' mes données) ainsi que mes partitions ubuntu....
Voici les manipulations que j'ai faites :
- j'ai essayé de recréer la table de partition avec sfdisk mais il a fait n'importe quoi, il a trouvé une partition logique /dev/sda5 en dehors de la partition étendue /dev/sda4 (et en dehors du dd).
- toujours avec sfdisk, j'ai finalement supprimé /dev/sda5 de la table, je me retrouve avec la table de partition suivante :
sudo fdisk -l /dev/sda
Disk /dev/sda: 477 GiB, 512110190592 bytes, 1000215216 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes
Disklabel type: dos
Disk identifier: 0x8858596d
Device Boot Start End Sectors Size Id Type
/dev/sda1 * 2048 718847 716800 350M 7 HPFS/NTFS/exFAT
/dev/sda2 718848 208764927 208046080 99.2G 7 HPFS/NTFS/exFAT
/dev/sda3 826302464 1000214527 173912064 83G 5 Extended
/dev/sda4 208764928 826302463 617537536 294.5G 7 HPFS/NTFS/exFATJe précise que j'ai l'erreur suivante quand je tente de monter /dev/sda4 qui était une partition formatée en NTFS:
Unable to detect file system! Possible reasons are:
- The file system is damaged
- The file system is unknown to GParted
- There is no file system available (unformatted)
- The device entry /dev/sda4 is missingDernière modification par mewyn (Le 21/05/2016, à 22:36)
