Impossible de booter après nouvelle installation

Bonjour,
Cela fait presque une semaine que j’essaie de booter ma nouvelle installation. J’ai réinstallé Debian 12 pour avoir une installation propre.
Je pense avoir tout essayé sur le bios MSI de ma carte mère: UEFI, UEFI + legacy
Je vois le choix Debian, Debian recovery, UEFI commandes mais ensuite il n’y a aucun signal sur l’écran.
J’ai fait un diagnostic boot-repair
Merci pour toute aide à la solution

Le menu de GRUB.

Suite à quoi ?
Qu’entends-tu exactement par « aucun signal sur l’écran » ?

Bonjour Pascal,
Le processeur trottine 1 à 2 secondes puis s’arrête et l’écran devient noir dans le silence et affiche no signal.
Merci

Comment ça, « le processeur trottine » ? Un processeur, ça ne se voit pas et ça ne « trottine » pas. Merci d’être précis dans les descriptions.

ça travaille deux secondes puis ça s’arrête.

GRUB reste affiché pendant 2 s ?

Ça affiche les choix, Debian, Debian recovery, UEFI commandes puis rien sur l’écran, une fois le choix fait, juste un bruit. Ça boote brièvement sur quelque chose qui ne peut poursuivre sur le système.

Qu’est-ce qui « travaille », comment vois-tu que « ça travaille » ? Voyant d’activité ou bruit du disque dur ?
Il faut être plus précis, on n’est pas devant ton écran !

Tu as pourtant écrit que le menu de GRUB s’affichait. Normalement il doit s’afficher pendant un compte à rebours de 5 seconde, puis sans appui sur le clavier pendant ce temps GRUB lance l’entrée de menu sélectionnée par défaut. En cas d’appui sur le clavier, le compte à rebours s’interrompt ; la touche « Entrée » lance immédiatement l’entrée de menu sélectionnée ou affiche les entrées du sous-menu s’il s’agit d’un sous-menu (Advanced options), les touches fléchées haut et bas changent l’entrée de menu sélectionnée. La touche « e » ouvre l’éditeur permettant de modifier l’entrée de menu sélectionnée.
Est-ce que tout cela fonctionne ? Est-ce que le problème se produit uniquement après le lancement de l’entrée de menu sélectionnée ou avant ?

Ça se produit après, plus rien n’est envoyé sur l’écran, quel que soit ce que je choisis.

Il n’y a vraiment rien qui s’affiche même transitoirement en démarrant en mode recovery ?
Avec le noyau 6.1.0-22 ? Ce noyau est le même que celui de l’installateur qui s’est bien lancé.
En ajoutant « nomodeset » à la ligne de commande du noyau ?

Non rien l’écran rescanne les connexions pour trouver la bonne à la carte graphique puis affiche no data.
