Reinstaller GRUB 2

Bonsoir,

hier soir j'ai eu un problème, mon ubuntu à complètement freeze, et j'ai du couper l'alimentation de mon ordi pour faire quelque chose. En redémarrant, j'ai boot sur GRUB Rescue, j'ai pas cherché à comprendre j'ai de suite lancé une session live ubuntu pour utiliser boot-repair. J'ai fais l'option recommandé, mais maintenant je boot automatiquement sur windows 10.
Si quelqu'un peut m'aider ça serait sympa.

Voila le fichier généré par boot-repair, merci d'avance !

Re : Reinstaller GRUB 2

Salut,

Ta partition étendue a visiblement subi des dégâts :

sda2: __________________________________________________________________________
    File system:       Extended Partition
    Boot sector type:  Unknown
 
sda5: __________________________________________________________________________
    Mounting failed:   mount: unknown filesystem type ''

Essaie de voir si Testdisk est capable de la récupérer. Sinon, il faudra probablement réinstaller, après avoir vérifié l'état du disque avec un rapport smart.

On peux utiliser Testdisk depuis une session live ubuntu ?

Re : Reinstaller GRUB 2

Bonsoir
Dans ton boot-info, j'ai vu cela

/dev/sda1    *          2,048   312,571,903   312,569,856   7 NTFS / exFAT / HPFS
/dev/sda5         312,573,952   616,763,391   304,189,440  83 Linux

Dans l'image que tu as fournie
il me semble que la première partitionb est vue comma ayant une taille de  312569856
et la seconde de 304189440

Tu as donc le choix classique de
A) Sauver tes données et de réinstaller
   Pour cela tu descends d'une ligne pour te positionner sur la partition LINUX puis faire P
  Tu devrais voir apparaitre le répertoire /home
B) Ce qui me semble préférable, Réécrire la table de partition  rebooter et refaire boot-repair
  Malheureusement, Tu n'as pas listé ce qui avait été découvert Juste avant, au moment de la proposition write.
  Je pense que c'était uniquement tes trois partitions.
