Réorganisation partitions et multiboot [RÉSOLU]

Bonsoir,

Sur mon disque dur numéro 2, j'ai 2 versions de ubuntu. La 14.04 LTS et la 16.04 LTS en multiboot.
Ayant transféré vers la 16.04 les fichiers dont j'avais besoin, je souhaite supprimer la 14.04 pour faire profiter de tout l'espace sur le disque dur la version 16.04.
Une image de Gparted :
395645Capturedcran20180103190409.png
J'ai pensé à supprimer /dev/sdb1 et /dev/sbd2 et le swap. Ensuite agrandir et décaler vers la gauche /dev/sdb5 et /dev/sdb6 et remettre 16 GO de swap à la fin. Disons 150 GO pour la racine et 350 GO pour le /home. J'utiliserai uns clé USB live "Boot repair disk" contenant Gparted et l'utilitaire pour remettre d'aplomb le GRUB. Mon disque dur numéro 1 ayant windows xp et le numéro 3 windows 7.
Est-ce la bonne méthode ? et une bonne idée ?

Merci pour vos réponses.
Et bonne année wink

Re : Réorganisation partitions et multiboot [RÉSOLU]

Bonjour et bonne année,
Cette opération que tu veux faire est risquée. Aussi, je te recommande de sauvegarder sur un DD externe les documents précieux que tu peux avoir sur ce disque dont tu veux réaménager le partitionnement. Cela étant fait, moi je te recommanderais une installation toute neuve de Ubuntu 16.04 en écrasant le partitionnement actuel. Le mieux étant la création d'une nouvelle table de partitions MSDOS pour partir sur du tout neuf et tout propre.

Re : Réorganisation partitions et multiboot [RÉSOLU]

Installer et passer du temps à tout reconfigurer c'est justement ce que je cherche à éviter.
Il m'est venu une autre idée. Ayant lu des témoignages indiquant que Gparted pouvait mettre de longues heures à déplacer une partition, cela m'a un peu refroidi.
Sachant que je sauvegarde toutes les partitions de mon disque dur vers un DD externe avec un livecd Clonezilla, ne serait-il pas plus simple de virer toutes les partitions, d'en recréer 2  (plus grandes) + le swap et de restaurer la root el le home ? quitte à demander à Clonezilla de s'occuper de la nouvelle taille ? D'après la doc, il sait le faire.

Bonjour,
C'est peut-être possible avec Clonezilla mais je ne l'ai jamais fait et je ne saurais pas t'aider si tu as des ennuis dans cette opération.

Re : Réorganisation partitions et multiboot [RÉSOLU]

Voici ce que j'ai fait avec Gparted :
- Supprimé sdb1, sdb2 et le swap
- Copié et collé à gauche sdb5 et sdb6 dans l'espace ainsi libéré et non alloué
- Supprimé sdb5 et sdb6 dans la partition étendue
- Supprimé la partition étendue sdb4
- Redimensionné, agrandi, sdb5 (/) et sdb6 (home)
- Remis le swap à la fin
Le DD fait 500 GO et je voulais que Xubuntu 16.04 l'occupe seul.
Appliqué et le tout en terminé en 30 minutes. 10 GO et 33 GO de données effectives à déplacer. On est loin des 10 heures que j'avais lu dans un forum...
J'ai ensuite utilisé Boot Repair Disk pour qu'il me remette le Grub. Toutefois, il a fait du zèle et est allé se mettre aussi dans le premier disque dédié à Windows.

Le problème est que le démarrage est plus long, entre 1 et 2 minutes. J'ai lu que ça pouvait être causé par un bug connu du Grub.

Ce serait utile que tu fasses un Boot-Info depuis une session de ton Ubuntu installé en suivant les indications du paragraphe 1.1 Cas où au moins un ubuntu installé sur disque est opérationnel. Tu donneras l'URL de ce Boot-Info dans ta réponse. Je pourrai vérifier s'il n'y a pas une petite vacherie (du genre UUID qui ne va pas) susceptible de créer ce temps de démarrage long.

A la louche, je dirais qu'avant il mettait une petite minute mais pas plus.

User choice: Est-ce que sdb (ATA WDC WD5000AAKX-0) est un disque amovible ? no




=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub2 of sdb1 into the MBRs of all disks (except live-disks and removable disks without OS).
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le disque sdb (ATA WDC WD5000AAKX-0) !

Les fichiers de démarrage de [Ubuntu 16.04.3 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)


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

Je pense que la lenteur au démarrage est due à l'UUID de la partition swap qui est faux dans le fstab.
Il faut éditer le fichier /etc/fstab avec pouvoir administrateur (*) et modifier la ligne suivante : 

UUID=35628cb2-058a-4d5a-91be-e92f5bb499b2 none            swap    sw              0       0

pour qu'elle devienne : 

UUID=149ffeb9-17ff-47c6-93cd-13da45713ab5 none            swap    sw              0       0

Après ça, au prochain démarrage, le temps de démarrage aura diminué de très exactement 90 secondes. Ce délai correspond à la temporisation adoptée par cette daube de systemd quand il n'arrive pas à monter une partition.

(*) je détaille la procédure (c'est à faire depuis une session du Ubuntu installé) :
1) installer gksu en vue d'utiliser gksudo : https://forum.ubuntu-fr.org/viewtopic.p … #p19459481
2) ouvrir le fichier fstab dans gedit avec pouvoir administrateur en collant ça dans le terminal : 

gksudo gedit /etc/fstab

Re : Réorganisation partitions et multiboot [RÉSOLU]

Hé bien merci Malbo. Avec ce changement de valeur UUID, le démarrage est plus rapide maintenant.
Je mets en résolu.
