[Résolu] Disque dur invisible au boot, mais présent sous ubuntu live

Bonjour à tous,

Moi c'est Luc, étudiant en cinéma qui est passé à Linux depuis quelques années (mais en utilisateur lambda qui a toujours du mal à piger le terminal), je viens vous déranger un peu car j'ai un problème très ennuyeux.

J'ai installé depuis peu un Ubuntu 14.04 LTS en dual boot sur la machine d'une amie (un ASUS ROG G551JW-DM138H), en cohabitation avec un Windows 10 (qui était initialement un Windows 8 mais que son frère a "upgradé").

Problème, hier, Ubuntu était lancé, la session a "freezé" alors que mon amie surfait sur le net, elle l'a éteinte en appuyant 5 secondes sur le bouton d'allumage, et depuis, l'ordinateur ne veut plus démarrer. Lorsqu'on l'allume, il passe sur le BIOS. Après avoir cherché un peu, visiblement, le BIOS ne reconnaît plus le disque principal, qui donc ne se lance pas (pas d'écran pour choisir entre Ubuntu et Win 10, on passe directement au BIOS).
Lorsque je branche une clef USB sur laquelle se trouve une image Ubuntu faite avec Lili USB creator, l'ordinateur la reconnaît, je peux démarrer en live session. Étrangement, lorsque je suis en live session, j'arrive à accéder aux données du disque dur, donc il n'est pas HS, il ne veut simplement pas booter. J'ai donc tenté un boot-repair qui m'a donné ces résultats et m'a dit de redémarrer. Mais ça ne marche toujours pas.

J'avoue être désemparé, mes connaissances en informatique étant bien trop sommaires pour me sortir de ce pétrin.

Sauriez-vous où se trouve le problème ? Comment je peux le réparer ?

En vous remerciant par avance,
Luc

Re : [Résolu] Disque dur invisible au boot, mais présent sous ubuntu live

Ah oui en effet, au temps pour moi, le disque dur est bien mort. Les deux NTFS ne sont que deux partitions d'un second disque pour les données. J'ai confondu le /home qui était présent sur le disque avec celui qui est mis en place par la live session.

Merci beaucoup, et désolé de ne pas avoir vu ça de suite ! ^^'
