Impossible de récupérer l'ancienne partition après un Dual Boot

Bonsoir,

Je poste ce message car j'ai un léger problème suite à un dual boot Ubuntu/Windows. J'avais fait l'installation d'Ubuntu en dual boot avec Windows de manière standarde, mais après quelques jours j'en voulais plus car il était trop lent, et j'ai donc formaté la partition crée pour l'installation d'Ubuntu afin de récupérer l'espace et le re-donner à Windows par la suite. Sauf que impossible de redonner l'espace, Ubuntu est bien désintallé, mais quand j'accède à la partition via le menu du boot ça m'enmène sur Grub, et c'est donc pour savoir si il y a moyen de virer Grub de la partition pour pouvoir redonner l'espace à Windows.

Merci beaucoup !

Tu racontes mal les histoires ou c'est moi qui ne comprends rien. Ma question : est-ce que tu parviens à démarrer sur Windows actuellement ?

Oui désolé pour le manque d'explication je suis un peu novice hmm
Oui j'arrive parfaitement à démarrer Windows, sauf qu'après formatage de la partition Ubuntu, quand j'accède au menu dual boot et que je la sélectionne, ça me met sur Grub. Sauf que j'aimerais "virer" ce Grub pour pouvoir redonner cette partition à Windows car ça m'est impossible jusqu'ici, sinon j'aurai 160Go de HDD dans le vide quoi hmm

Merci pour ce complément d'info.
Quelle est la version de Ubuntu que tu as installée (16.04, 18.04, autre) ?

Je te prie de démarrer sur une LiveUSB de Ubuntu 18.04.1 64 bits (ma recette pour la faire depuis Windows ici) et de sélectionner "Essayer Ubuntu..." ("Try Ubuntu..." si c'est en anglais) afin de faire une session live. Tu feras un Boot-Info depuis la session live et tu donneras l'URL de ce Boot-Info dans ta réponse.

Je vois la mention "Microsoft LDM" concernant le disque dur de 1 To, ce qui signifie un partitionnement dynamique (on parle de LDM ici). Je ne suis pas à l'aise avec ça. Je te conseillerais de déconnecter physiquement ce disque dur afin de vérifier que ton Windows peut toujours démarrer sans ce disque dur. Si c'est le cas, tu devrais pouvoir le reconnecter et trouver le moyen de le reformater depuis Windows afin de pouvoir t'en servir.
Si ton Windows a besoin de ce disque dur pour fonctionner, moi je ne sais pas te conseiller pour sortir de cette mélasse.

Re : Impossible de récupérer l'ancienne partition après un Dual Boot

Donc si j'arrive à démarrer Windows correctement sans le HDD, je devrais le formater complétement si j'ai bien compris ? smile

Re : Impossible de récupérer l'ancienne partition après un Dual Boot

Je vais compléter : non seulement il faut arriver à démarrer sur Windows mais je te prie de vérifier depuis ta session Windows que tu as bien accès à toutes tes données (tes documents). Il faut être sûr qu'il n'y a pas de données précieuses pour toi qui resteraient stockées dans le disque dur puisqu'il faudra le formater. Si c'est bien le cas et que toutes tes données précieuses sont bien là, tu pourras reconnecter le disque dur et le formater (tout ce qui était dessus sera effacé). Concrètement, il faudra créer sur ce disque dur un partitionnement de base (au lieu du partitionnement dynamique). Tu demanderas pour cela de l'aide chez Windows.
