Ubuntu non détecté lors du démarrage

Cracramon

Bonjour,
J'ai partionné aujourd'hui mon PC portable (une première) et j'ai tenté d'installer ubuntu avec une clef USB (une première aussi).
Tout se passait bien, jusqu'au moment fatidique, où une fois installé, mon PC ne me propose jamais (même dans le BIOS) de lancer Ubuntu.
J'ai voulu réinstallé, mais là j'ai eu la confirmation que Ubuntu avait bel et bien installé.

J'ai tenté de trouver des réponses dans la FAQ, mais mon niveau informatique n'étant pas très avancé, je dois avouer être un peu perdu.

Je vous joins le pastebin de boot repair, en espérant que vous saurez m'aiguiller.

Un tout grand merci à vous,
Cracramon.

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub2 of sda5 into the MBR of sda.
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot


=================== Final advice in case of suggested repair


Les fichiers de démarrage de [Ubuntu 18.04.3 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.

Bonsoir,
Je suis arrivé à lancer Ubuntu en dualboot, simplement en acceptant la réparation préparée par Boot-Repair.

Etant dans une filière liée à l'informatique (Bio-informatique avec un background de biologie) j'aimerais quand même avoir quelques précisions quant à l'erreur.

(Aussi, je comprends pas pourquoi j'ai deux partitions qui sont reliées à windows et qui lancent windows)

Merci.

Watts

Bonjour,

Tu as commis une erreur en installant le chargeur d'armorçage grub, qui doit se trouver en début de disque dans le MBR. Avant la réparation, tu avais encore le mbr type windows, qui ne lance pas Ubuntu. La réparation recommandée a mis grub dans le MBR, qui peut ainsi lancer Ubuntu

Bonjour,
j'ai trouvé également un loup dans cet extrait :

"blkid" output: ________________________________________________________________

Device           UUID                                   TYPE       LABEL

/dev/loop0                                              squashfs   
/dev/sda1        7E1C2F0A1C2EBD51                       ntfs       Réservé au système
/dev/sda2        30CC5277CC5236F6                       ntfs       Win 10
/dev/sda3        10C4B10FC4B0F7D4                       ntfs       linux

On y voit que le partitionnement a été fait avec la gestion des disques de Windows. C'est là que tu as créé une partition au format NTFS à laquelle tu as décidé de donner le nom "linux" (c'est /dev/sda3). Il ne fallait pas faire ça : on ne crée pas une partition destinée à Linux depuis la gestion des disques de Windows. Il fallait seulement laisser un espace non partitionné destiné à Linux. Résultat : cette partition étant dans un format NTFS - donc un format Windows - elle n'a pas été utilisée par l'installateur de Ubuntu. A l'issue de l'installation, tu te retrouves avec cette partition inutilisée.
