Dualboot w8 / ubuntu GRUB KAPUT s.o.s

Bonjour.

Suite à une manipulation foireuse (je débute sous ubuntu)

Je viens de foutre en l'air mon dual boot w8 / debian 7 kde.

Ducoup, me servant de mon ordi pour gagner ma croûte, je me retrouve dans une situation très inconfortable. Je rédige ce message sur un smart phone éclairé à la lumière blafarde d'un prompt qui affiche froidement :

"error: invalid arch independant ELF magic.
Entering rescue mode...
grub rescue>  _"

Le tout surmonté par un bug graphique imposant.

Si je boot sur Debian, la même chose se produit, sans bug graphique.

La commande "set" renvoie :

"Prefix=(hd1,gpt4) /boot/grub
root=hd1,gpt4"

Je me suis donc empressé de graver une image de boot repair, puis de l'exécuter.
Un prompt m'indique que je suis en legacy, et qu'il se pourrait que je veuille passer en EFI (si j'ai bien tout saisis). N'y voyant aucune injonction, j'ai foncé.

Un message m'indique que l'opération est un échec, et me génère ce rapport.
http://paste.ubuntu.com/6419941

Amis éclairés, je m'en remet humblement à vous.

0n y voit que c'est bien un dual-boot avec Debian. Ubuntu, je connais mais là, avec Debian, c'est inconnu pour moi . Tu devrais poster dans cette discussion : http://forum.ubuntu-fr.org/viewtopic.php?pid=4726141
en donnant le lien vers la présente discussion afin de demander de l'aide. En effet, c'est le concepteur de Boot-repair qui a créé la discussion précisément pour cela. Il se pourrait qu'il mette un peu de temps à répondre mais il devrait répondre ici dans la discussion que tu as créée.

Re : Dualboot w8 / ubuntu GRUB KAPUT s.o.s

Bonsoir,
J'ai vu que tu as posté comme je t'avais suggéré pour demander de l'aide : http://forum.ubuntu-fr.org/viewtopic.ph … #p15215181
Comme l'aide tarde à venir, je te suggère d'envoyer directement un mail à YannUbuntu (ici) en lui demandant d'intervenir dans la présente discussion (donne bien le lien vers la présente discussion)
