Partition boot remplie sur Debian 13
Ma partition boot s'est remplie. Une mise à jour avec un nouveau noyau n'a pas pu se faire correctement et quand j'essaye de démarrer, je me retrouve dans “grub rescue”…
J'ai booté sur une clé usb que j'avais sous la main (fedora workstation live).
À partir de là, je peux avoir un terminal complet, un clavier bien configuré (et pas un qwerty..). L'objectif va être de nettoyer la partition grub mais aussi de chroot sur mon installation pour pouvoir relancer une mise à jour.
$ sudo -i # blkid (partitions de la clé usb) /dev/sda5: ... #partition principale chiffrée /dev/sda1: ... #partition boot
(Note: On peut aussi utiliser lsblk ou fdisk pour voir les partitions.)
Bon, maintenant, faut les monter ces partitions. Je vais suivre les instructions de ce tutoriel.
