Mise à jour Ubuntu 24.04.1 LTS plus d'affichage du boot loader
Bonjour,
J'ai fait hier la mise à jour Ubuntu de la 22.04 vers la 24.04.1 LTS
Le processus s'est passé correctement, mais maintenant je ne vois plus le boot loader grub au démarrage.
J'ai essayé de le réinstaller avec la commande:
sudo grub-mkconfig -o /boot/grub/grub.cfg
La commande se déroule sans erreur et voit le linux et le Windows 7, la date du fichier grub.cfg se met à jour, mais toujours pas de boot loader au démarrage.
Si quelqu'un à une idée sur ce problème je suis preneur.
Merci d'avance,
Modération : Si j'ai bien compris il ne s'agit pas d'une mise à jour mais d'une migration. Donc déplacé dans la section adéquate.

Ça aurait été bien qu’on puisse faire le même constat que toi grâce au retour de la commande.
Bref, donne s’il te plaît les retours de :
cat /etc/default/grub
cat /boot/grub/grub.cfg

Re : Mise à jour Ubuntu 24.04.1 LTS plus d'affichage du boot loader
C’est bien ce que je supposais, Windows n’est pas présent dans le menu car il n’y a pas de détection d’autres OS lors de sa construction.
Donne le retour de :
