RESOLU installation en multiboots de Xubuntu après Lubuntu

Bonjour.

Je souhaiterais installer Xubuntu 18.04 en multi-boot sur un ordinateur sur lequel se trouve déjà Lubuntu 18.04, mais au moment de l'installation l’installateur ne trouve pas que Lubuntu 18.04 est déjà installé et ne me propose pas d'installer Xubuntu 18.04 en multi-boot.
Il me propose d'écraser tout ce qu'il y a sur le disque dur pour y mettre Xubuntu 18.04.

Comment faire pour permettre l'installation en multi-boot de plusieurs distributions ?

L'ordinateur a un disque dur de 80 Go et mon projet est de créer 4 partitions de 20 Go pour installer 4 distributions.

Merci pour votre aide.

Re : RESOLU installation en multiboots de Xubuntu après Lubuntu

Bonjour,
Au lieu de sélectionner l'installation de Xubuntu 18.04, je te prie de sélectionner "Essayer Ubuntu..." ("Try Ubuntu..." si c'est en anglais) afin de faire une session live Xubuntu 18.04. Tu feras un Boot-Info depuis cette session live et tu donneras l'URL de ce Boot-Info dans ta réponse. Motif de ma demande : vérifier que le mode de démarrage(*) de la session live Xubuntu 18.04 est bien le même que le mode de démarrage du Lubuntu déjà installé. Si ce n'est pas le cas, ça pourrait expliquer tes difficultés.

(*) si c'est un ordi pas trop vieux, ce mode de démarrage peut être UEFI ou bien Legacy (mode Bios traditionnel)

Re : RESOLU installation en multiboots de Xubuntu après Lubuntu

Merci Malbo pour ta réponse.

J'ai constaté en installant différentes distributions (Lubuntu, Xubunt, Linux Mint Mate et Xfce) que le multi-boot n'était souvent pas proposé (distribution déjà installée non reconnue) et, quand j'avais réussi à installer Lubuntu après Xubuntu, je n'arrivais pas à lancer Xubuntu.
L'installation de différentes distributions en multi-boot m’apparaît donc comme un projet aux résultats non fiables.

J'ai donc choisi d'installer uniquement Xubuntu.

Le résultat de la commande " sudo boot-info " (sans RAID - Je ne sais pas ce que c'est) :
  - sur Xubuntu 18.10 est " http://paste.ubuntu.com/p/kBv4cHCV7W/ ".
  - sur Lubuntu 18.04 en session live est http://paste.ubuntu.com/p/3XmTjxk3xr.

A +

=================== Suggested repair
The default repair of the Boot-Repair utility would purge (in order to enable-lvm) and reinstall the grub2 of mapper/xubuntu--vg-root into the MBR of sda.
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 TOSHIBA MK8046GS) !


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

J'ai un gros doute que j'aimerais bien lever. Je te prie de passer la commande suivante depuis une session de ton Xubuntu 18.10 :

systemd-analyze time

Et donner le retour utilisable de cette commande dans ta réponse.

Re : RESOLU installation en multiboots de Xubuntu après Lubuntu

Bonjour.

Le résultat de la commande "systemd-analyze time" est :

Startup finished in 39.032s (kernel) + 1min 4.929s (userspace) = 1min 43.961s
graphical.target reached after 1min 3.397s in userspace

Bonjour,
Ce temps "kernel" est excessif. Il est dû à l'utilisation de LVM. C'est parce que tu as coché la case "Utiliser LVM pour la nouvelle installation de Ubuntu" à l'étape Type d'installation. Je te recommande de faire une nouvelle installation en écrasant la présente installation mais cette fois, tu ne cocheras pas la case "Utiliser LVM pour la nouvelle installation de Ubuntu".
