Bonjour,
Un proche m’a demandé de dépanner son pc qui a le problème suivant. Le démarrage après Grub, plante et Ubuntu ne démarre pas. Démarrer le kernel 5.4.0.42 précédent permet de démarrer Ubuntu.
Sachant dépanné, je n’ai diagnostiqué aucune erreur, ni système, ni disque dur, je n’ai plus d’idée. J’ai tout de même réparé les paquets, réparé et réinstallé grub, mais aucun changement. Les paquets n'étaient pas altérés.
Lors du problème, pas d’erreur, pas de message, juste le tiret en haut à gauche qui clignote.
Pourriez-vous m'aider svp à identifier la cause ?

Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub2 of
sda1 into the MBR of sda.
Additional repair would be performed: unhide-bootmenu-10s
J'ai réparé les paquets avec ça, mais aucun paquets n'était altéré et les mises à jour sont à jour.
sudo apt update && sudo dpkg --configure -a && sudo apt install -fy && sudo apt autoclean && sudo apt autoremove --purge -y && sudo apt full-upgrade -y
J'ai réinstallé grub avec ça, mais aucun changement. Le rédémarrage à chaud fonctionne bien mais le redémarrage à froid crash parfois.
sudo os-prober
sudo update-grub
sudo grub-install /dev/sda
