Grub n'est pas lancé au démarrage (boot-info disponible)

Bonjour,
J'ai un ASUS G2P, sur lequel j'ai récemment remplacé le disque dur interne d'origine par un SSD de 500Go.
J'ai d'abord restauré, à partir de la dernière sauvegarde ISO, mon ancien Windows 7 Pro, qui fonctionne comme avant.
Puis je viens d'installer Ubuntu-Unity, version 16.02.2 LTS, sur une autre partition primaire, sans rencontrer de problème au cours de l'installation, sauf qu'au redémarrage, Grub n'est pas lancé, et c'est toujours Windows 7 Pro qui démarre.
(Je précise que Grub fonctionnait sur le disque dur interne d'origine, avec la version 14.04.3 d'Ubuntu, qui cohabitait avec le même Windows 7 Pro.)

J'ai trouvé dans la documentation d'Ubuntu comment produire un fichier boot-info et j'ai noté que je dois le soumettre au forum avant de lancer la réparation de Grub.
Je ne sais pas comment envoyer le fichier boot-info en question, car je ne vois pas d'option "joindre un fichier". Est-ce que je peux faire un copier/coller directement dans un message comme celui-ci ?
Merci pour le temps que vous allez consacrer à un débutant !
Bien cordialement,
Jean

Bonjour,
Il suffit de recopier le lien donné par boot-Info;
On peut aussi copier / coller le boot-Info mais en prenant soin de le mettre entre balises. Ce sont les 2 flèches bleues <>

Bonjour.

Je ne sais pas comment envoyer le fichier boot-info en question, car je ne vois pas d'option "joindre un fichier". Est-ce que je peux faire un copier/coller directement dans un message comme celui-ci ?

Pour t'éviter de refaire le boot info.
Depuis la même session live qui a servi à installer. comme tu as accès à internet en session live.
Tu navigues dans les fichiers système de ton Ubuntu où de ton Windows pour trouver un dossier  "boot-sav"

Dans Windows, il se trouve dans la racine du système.
Dans le Ubuntu installé, il se trouve dans  /var/log/boot-sav

Tu déroules boot-sav, jusqu'à trouver un fichier texte " RESULTS.txt" . C'est la copie du boot info que tu as fait.
Il n'y a qu'à en poster le contenu dans ta réponse entre les balises code (les deux  <>  bleu au dessus de la fenêtre qui te sert à poster).

@+.  Babdu89   .

J'ai découvert Ubuntu avec la 07.10.... Et alors?!...  Depuis je regarde de temps en temps si Windows marche toujours....

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to) and reinstall the grub2 of sda3 into the MBR of sda.
Additional repair would be performed: unhide-bootmenu-10s


=================== User settings
The settings chosen by the user will not act on the boot.

Re : Grub n'est pas lancé au démarrage (boot-info disponible)

Bonsoir.

En complément de ce que préconise malbo. @malbo, bonsoir.
Explication de ce qui à amené à cette situation.

Comme on voit une installation avec partition /home séparée /dev/sda5. Tu as utilisé l'installation manuelle,en passant par "Autre chose".
Tu as installé ton Ubuntu en mettant la première partie de Grub dans le secteur d'amorçage de la partition d'installation de ton Ubuntu, on voit çà ici en gras.

sda3: __________________________________________________________________________

    File system:       ext4
    Boot sector type:  Grub2 (v1.99-2.00)
    Boot sector info:  Grub2 (v2.00) is installed in the boot sector of sda3
                       and looks at sector 784101080 of the same hard drive
                       for core.img. core.img is at this location and looks
                       for (,msdos3)/boot/grub. It also embeds following
                       components:
                       
                       modules
                       -------------------------------------------------------
                       fshelp ext2 part_msdos biosdisk
                       -------------------------------------------------------
    Operating System:  Ubuntu 16.04.2 LTS
    Boot files:        /boot/grub/grub.cfg /etc/fstab
                       /boot/grub/i386-pc/core.img

Alors qu'elle devrait être installé dans le secteur d'amorçage du disque d'installation. /dev/sda

=> Windows 7/8/2012 is installed in the MBR of /dev/sda.

Lorsque tu auras fait la réparation recommandée, stp, poste le boot info qui sera indiqué en fin d'utilisation de Boot-Repair.  On devrait y voir quelque chose qui ressemble à ceci;

=> Grub2 (v2.00) is installed in the MBR of /dev/sda and looks at sector 1 of
    the same hard drive for core.img. core.img is at this location and looks
    for (,msdos3)/boot/grub. It also embeds following components:
   
    modules
    ---------------------------------------------------------------------------
    fshelp ntfs part_msdos biosdisk
    ---------------------------------------------------------------------------

Normalement, on ne verra pas de changement dans la partition /dev/sda3.

Il me semble aussi que l'on pouvait utiliser une autre solution.
Installer/utiliser "Easy-boot-bcd "dans Windows, ce qui permet en démarrant sur Windows et de choisir de lancer Windows ou Ubuntu.
malbo confirmera ou pas...

Remarque.
C'est la première foi que je vois une installation où Windows est installé dans une partition étendue, et qui fonctionne, çà contredit ce que l'on a souvent vu et lu dans le forum. Windows devant être installé dans une partition principale...

Re : Grub n'est pas lancé au démarrage (boot-info disponible)

@Babdu89 : merci pour ce complément. Je n'avais même pas vu le coup de Grub installé dans le secteur de boot de la partition racine (*).
Par contre Windows n'est pas installé dans une partition étendue : sda2 est une partition primaire.

(*) quand la "Réparation recommandée" aura été faite, je guiderai jeancesaravon pour mettre à jour Grub suivant ce tuto.

Re : Grub n'est pas lancé au démarrage (boot-info disponible)

Bonjour et merci Hemger, Babdu89 et Malbo !

Apres le boot-repair, Grub est sur sda, avec encore la recommandation de le transferer de sda3 vers sda... voir le boot-info ci-dessous.
Au redemarrage, apparait l'invite grub> en "mode minimal".
Pour pouvoir vous ecrire, j'ai  lance l'option Try Ubuntu du DVD, sans les accents !

Je peux aussi tout reinstaller (Windows depuis mon ISO, Ubuntu depuis le DVD) : merci de me dire alors comment eviter de mal installer Grub.
Voici le boot-info, en vous souhaitant bonne lecture.
Bien cordialement,
Jean

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to fix packages fix executable) and reinstall the grub2 of sda3 into the MBR of sda.
Additional repair would be performed: unhide-bootmenu-10s


=================== User settings
The settings chosen by the user will not act on the boot.

Re : Grub n'est pas lancé au démarrage (boot-info disponible)

J'ai du mal à comprendre pourquoi ça merde mais à présent, tu n'as même plus de fichier sda3/boot/grub/grub.cfg (le fichier de configuration de grub) alors que tu l'avais dans le Boot-Info du post #4. Au lieu d'avancer, ça régresse. Sans ce fichier grub.cfg, c'est normal que tu aies un "Minimal BASH-like" au démarrage puisque le chargeur d'amorçage qui se trouve dans le MBR du disque dur a la consigne d'aller fouiller dans le grub.cfg sensé se trouver dans la partition racine pour proposer le menu Grub.

EDIT : il y a une chose que j'aimerais bien savoir : est-ce que tu peux aller sur internet quand tu es en session live ?

Re : Grub n'est pas lancé au démarrage (boot-info disponible)

Bonjour.

EDIT : il y a une chose que j'aimerais bien savoir : est-ce que tu peux aller sur internet quand tu es en session live ?

Pour pouvoir vous ecrire, j'ai  lance l'option Try Ubuntu du DVD, sans les accents !

Je regarde le dernier boot-info.

Tu as fais un boot info après la réparation avec Boot-Repair. Donc on ne voit pas ce qu'a fait la réparation.

Stp comme expliqué au post#3.
Veux tu bien allé dans le dossier boot-sav
Dans Windows, il est dans la racine de la partition système Windows.
Dans Ubuntu installé, il est dans;  /var/log/boot-sav/log/  dans le dossier "date,heure boot-repairxx" 
Il me semble que tu devrais avoir deux dossiers "date,heure boot-info xx" et un dossier "date,heure boot-repairxx"

Je pense que c'est celui de la réparation recommandée, nous poster le contenu du fichier " RESULTS.txt" que l'on puisse voir ce qu'a fait la réparation recommandée.

Merci.

J'ai découvert Ubuntu avec la 07.10.... Et alors?!...  Depuis je regarde de temps en temps si Windows marche toujours....

Re : Grub n'est pas lancé au démarrage (boot-info disponible)

Bonsoir aux trois !

Mon erreur d'installation a été d'imposer à Ubuntu une partition que j'avais créée moi-même. J'ai donc tout recommencé en évitant ce piège :

J'ai donc réinstallé Windows depuis mon ISO, puis supprimé toutes les autres partitions avec GParted, enfin laissé Ubuntu s'installer où il voulait.
Ubuntu a créé une partition avec TOUT l'espace non alloué (360Go), partition qu'avec GParted j'ai ramenée à 100Go, puis j'ai rapproché l'espace de Swap autant que possible, enfin créé une partition de 260Go pour mes données, accessibles depuis les deux OS.

Quand j'ai vu le dernier message de Babdu89, je n'avais déjà plus accès aux données qu'il voulait consulter, et j'en suis vraiment désolé.
J'ai fait un 3ème boot-info, qui ne signale plus d'erreur. Il suggère juste de rapprocher les fichiers de démarrage de Linux du début du disque, sur une petite partition de boot séparée. Mais comme mon BIOS détecte ces fichiers, je n'ai rien fait !

Merci aux trois de m'avoir permis de comprendre mon erreur, et par là d'y remédier.
Bien cordialement,
Jean
