[Résolu] pb de grub à l'installation ubuntu en double boot de win2K

jmfdescourvieres · Le 19/01/2018, à 12:19

Impossible d'avoir la fenetre grub multi boot après installation d'un 2 ieme OS.
Il sagit d'un PC Dell optiplex 320 (processeur Intel Pentium CPU 2.8 Ghz, multicore. rénové avec un disque dur 80 giga et 2 giga de ram.
J'ai installé une version windows 2OOO en sda1, afin de pouvoir utiliser un fichier excel avec macro pour la gestion de mes comptes, et en sda7 ubuntu 16.
Lors du boot la fenètre grub n'apparait pas, et le systeme boote directement sur ubuntu.
Le boot repair 32 bits ne me répare le grub. Il me propose bien d'intervenir mais je n'arrive pas à prendre la main.

J'ai lancé un boot info. voir https:// paste.ubuntu.com/26415573

merci pour votre aide à venir

Le Boot-Info a été fait depuis une session live d'une version obsolète de Boot-Repair-Disk comme on peut voir dans cet extrait :

boot-repair is executed in live-session (Boot-Repair-Disk 32bit 24avr2013, raring, Ubuntu, i686)

Je te recommande de ne plus utiliser cet outil obsolète. Tu vas démarrer en session Live sur ton support d'installation de Ubuntu 16.04.1 et depuis cette session live, tu vas faire un Boot-Info en suivant les indications du paragraphe 1.2 Cas où aucun ubuntu installé sur disque n'est opérationnel. Tu donneras l'URL de ce Boot-Info dans ta réponse.

merci pour cette 1ére réponse.
Voilà l'URL du nouvel boot info réalisé comme demandé ci-dessus: https:// paste.ubuntu.com/26416588
merci pour la suite

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub2 of sda7 into the MBRs of all disks (except live-disks and removable disks without OS).
Grub-efi would not be selected by default because: no-win-efi
Additional repair would be performed: unhide-bootmenu-10s


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le disque sda (ATA HDT722516DLA380) !

Les fichiers de démarrage de [Ubuntu 16.04.1 LTS] sont loin du début du disque. Votre BIOS pourrait ne pas les détecter. Vous voudrez peut-être re-essayer après avoir créé une partition /boot (EXT4, >200MB, en début de disque). Cela peut être réalisé via des outils tels que gParted. Puis sélectionnez cette partition via l'option [Partition /boot séparée :] de [Boot-Repair]. (http://doc.ubuntu-fr.org/tutoriel/partition_boot)


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

On y voit cet extrait qui montre ce qui va se passer si tu fais la réparation recommandée de Boot-Repair :

C'est bien ce qu'il convient de faire pour réparer ton démarrage aussi je te suggère de faire cette Réparation Standard de Boot-repair depuis la session Live de Ubuntu 16.04.1

jmfdescourvieres · Le 20/01/2018, à 11:52

Je viens de faire la réparation standard (à partir du live ubuntu, installer boot repair et boot-info puis lancer boot-repair), ça ne marche toujours pas. Quand je reboote, ça lance directement ubuntu (qui est en sda7).
Dans le boot-info que vous m'avez renvoyé (ci-dessus) il y a en fin une suggestion (en français):

mais je n'ose pas la faire, car je ne sais comment créé une partition /boot en début de disque, sans casser windows qui doit bien etre sur la première partition? Cette partition boot peut-elle être en sda3???
A noter que je peux très bien tout repartitionner et réinstaller... mais où mettre cette partition /boot.
Merci
Je vous redonne le nouveau boot-info, après avoir réalisé le boot-repair: http://paste.ubuntu.com/26421852/

=================== Recommended repair
The default repair of the Boot-Repair utility will reinstall the grub2 of sda7 into the MBRs of all disks (except live-disks and removable disks without OS).
Grub-efi will not be selected by default because: no-win-efi
Additional repair will be performed: unhide-bootmenu-10s



Reinstall the GRUB of sda7 into MBRs of all disks (except live-disks and removable disks without OS)

Le démarrage de l'ordinateur a été correctement réparé.

Vous pouvez maintenant redémarrer votre ordinateur.
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le disque sda (ATA HDT722516DLA380) !

Les fichiers de démarrage de [Ubuntu 16.04.1 LTS] sont loin du début du disque. Votre BIOS pourrait ne pas les détecter. Vous voudrez peut-être re-essayer après avoir créé une partition /boot (EXT4, >200MB, en début de disque). Cela peut être réalisé via des outils tels que gParted. Puis sélectionnez cette partition via l'option [Partition /boot séparée :] de [Réparateur de démarrage]. (http://doc.ubuntu-fr.org/tutoriel/partition_boot)

Je t'ai fait faire cette "Réparation standard" de Boot-Repair pour rien. J'avais lu trop vite ton post #1 et je n'avais pas compris que ton problème, c'est que le menu Grub est invisible.
Je te suggère la manip suivante :
1) installer gksu en vue d'utiliser gksudo : http://forum.ubuntu-fr.org/viewtopic.ph … #p19459481
2) appliquer l'astuce de Ccile suivant la procédure détaillée de ce post : http://forum.ubuntu-fr.org/viewtopic.ph … #p11447371

ok grand merci
ça marche..
Je vais pouvoir poursuivre: mettre une 3ieme install debian moins gourmande car le PC rame...

Merci
