[Résolu] pas de multi boot après seconde installation ubuntu

Bonsoir,
je viens d'installer une distribution ubuntu 16.04.3 sur le disque dur sda d'un pc AMD sur le il y avait déja un système Kubuntu.
le premier Kubuntu était installé sur une partition sda2 pour la racine et le /home sur une seconde sda1.
le second  Ubuntu a été installé sur deux nouvelles partitions sda7 pour la racine et sda6 pour le /home .
au redémarrage le système redémarre sur Kubuntu sans passer par un menu Grub.

voici le résultat de boot info :
http://paste.ubuntu.com/25797304/

merci d'avance

Re : [Résolu] pas de multi boot après seconde installation ubuntu

Je vois que ton grub est en "set timeout" = 0
Je penses qu'en changeant cela en 2 tu pourras appercevoir le grub durant 2 secondes, cependant lors du bbot tu peux aussi essayer de cliquer rapidement sur la flèche vers le bas , ce qui fera apparaitre ton grub, il faut cliquer très rapidement.
À ce stade c'est ce que j'essayerais en premier...

Re : [Résolu] pas de multi boot après seconde installation ubuntu

bonsoir,
En fait je crois que dans le grub, le paramètre "set timeout" était bien égal à 10.
en tout cas dans le fichier/etc/default/grub
je me suis contenté de lancer la commande :
sudo update-grub
j'ai redémarré le PC et j'ai bien vu apparaître le menu Grub2  et démarrer le système sur ma partition sda7
Merci à Enebre de sa réponse.

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub-efi-amd64-signed of sda2, using the following options:        sda4/boot/efi,
Additional repair would be performed: unhide-bootmenu-10s    use-standard-efi-file


=================== Final advice in case of suggested repair
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le fichier sda4/efi/.../grub*.efi !


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

On peut voir dans cet extrait du Boot-Info que Kubuntu est installé en mode EFI (présence de "signed grub-efi" sur la partition sda2) alors que Ubuntu est installé en mode non-EFI (présence de grub-pc sur la partition sda7) :

Cela peut fonctionner comme ça puisque tu sembles satisfait du résultat obtenu après "sudo update-grub" dans Kubuntu mais le principe général est d'installer tous les OS d'un ordi dans le même mode. Et là il n'est pas respecté. Comme Kubuntu avait été installé en premier en mode EFI, il convenait d'installer Ubuntu dans ce même mode EFI.

Re : [Résolu] pas de multi boot après seconde installation ubuntu

Bonjour et merci à malbo pour cette précision.
En effet , je ne maîtrise pas tout (loin de la) et lorsque j'ai voulu installer Ubuntu 16.04  à côté du Kubuntu je n'ai pas vu à quel moment de l'installation , il fallait préciser mode EFI ou non EFI.
je vais essayer de refaire l'installation à partir de la clé USB live.
pour le grub , c'est un peu au petit bonheur....
merci de me donner quelques pistes sur ces deux points et faut-il lancer systématiquement la commande sudo update-grub après l'installation ?

C'est plus vicieux que ça. Pour parvenir à installer en mode EFI, il faut démarrer en session live en mode EFI et vérifier que c'est bien le cas en passant la commande suivante (source) depuis la session live : 

[ -d /sys/firmware/efi ] && echo "Session EFI" || echo "Session non-EFI"

Si le résultat de cette commande donne "Session non-EFI", ce n'est pas la peine de lancer l'installation, ça va merder comme la première fois. Par contre, si c'est "Session EFI", tu peux lancer l’installation depuis la session live grâce à l'icône de l'installateur qui doit se trouver sur le bureau.

Re : [Résolu] pas de multi boot après seconde installation ubuntu

Bonjour et merci à Malbo.

j'ai donc vérifié que j'étais bien en mode UEFI en démarrant sur ma session Live via la commande 

[ -d /sys/firmware/efi ] && echo "Session EFI" || echo "Session non-EFI"

ce qui était le cas
j'ai donc réinstallé sur ma partition sda7 pour la racine et  en précisant d'amorcer sur le disque dur sda.
au final, j'ai bien au redémarrage le menu Grub2 qui me donne le choix entre Ubuntu (sur sda7) ou Kubuntu (sur sda2)
