Grub boot-repair problème

[Plumeau123]

Bonjour,
J'ai utilisé boot-repair et maintenant je ne suis plus capable de booter mon Linux Mint. Je suis un peu perdu. Linux est installé sur un ssd et j'ai une parition bios_grub GPT et tout ça a été configurer initialiement dans l'installateur de Mint et fonctionnait bien. Bootrepair à brisé mon grub.
Quelqu'un à une idée pour booter à nouveau mon Linux?
Voici les infos de bootrepair:

============================= Boot Repair Summary ==============================






Recommended repair: ____________________________________________________________

The default repair of the Boot-Repair utility will reinstall the grub2 of
sdf2 into the MBR of sdf.
Grub-efi will not be selected by default because no ESP detected.
Additional repair will be performed: unhide-bootmenu-10s



Unhide GRUB boot menu in sdf2/etc/default/grub

======================= Reinstall the grub2 of /dev/sdf2 =======================

chroot /mnt/boot-sav/sdf2 grub-install --version
grub-install (GRUB) 2.12-1ubuntu7.3

==> Reinstall the GRUB of /dev/sdf2 into the MBR of /dev/sdf

chroot /mnt/boot-sav/sdf2 grub-install /dev/sdf

Boot successfully repaired.

You can now reboot your computer.
Please do not forget to make your BIOS boot on sdf (Samsung PSSD T7 Shield) disk!

The boot files of [sdf2 (end>100GB)] are far from the start of the disk. Your BIOS may not detect them. You may want to retry after creating a /boot partition (EXT4, >200MB, start of the disk). This can be performed via tools such as gParted. Then select this partition via the [Separate /boot partition:] option of [Boot Repair]. (https://help.ubuntu.com/community/BootPartition)

Petite précision, j'ai toujours l'erreur "invalid arch independent ELF magic" de grub.
J'ai exécuter boot-repair à partir du live usb de Mint

Encore merci

[JUNGA]

Hello
et tu ne pourrais pas faire un retour en arrière via Timeshift, en utilisant le support d'installation?
NE PAS OUBLIER TA SIGNATURE MATÉRIEL ETC...

[Plumeau123]

Bonjour JUNGA,

Effectivement, je pourrais regarder pour le Timeshift, par contre je ne crois pas que timeshift peut restaurer le MBR... est-ce le cas?
Je vais regarder pour ajouter le tout à ma signature.

Merci"

[Plumeau123]

Je viens de faire un retour en arriere avec Timeshift mais ca ne boot toujours pas. Meme probleme

[Plumeau123]

Petit update de mon problème.
J'ai réussi à booter ma partition Linux à l'aide d'une clé USB de Super Grub2 Disk. Youpi!
Par contre, toujours incapable de faire fonctionner mon grub qui donne toujours l'erreur de ELF magic peut importe ce que je tente
Quelqu'un d'autre à des idées que je pourrais tenter?
Merci!

Bonjour,
Tu peux te chrooter à partir d'un Live USB et réinstaller grub.
Tu recherche la partition racine (pas celle de boot) de ton système avec :

Code : Tout sélectionner

lsblk

Genre un truc comme "/dev/sdfX" (le X est à adapter).
Tu te chroot :

Code : Tout sélectionner

sudo mount /dev/sdfX /mnt
sudo mount --bind /dev /mnt/dev
sudo mount --bind /dev/pts /mnt/dev/pts
sudo mount --bind /sys /mnt/sys
sudo mount -t proc /proc /mnt/proc
sudo chroot /mnt /bin/bash
sudo mount -a

Tu réinstalle grub :

Code : Tout sélectionner

sudo apt install grub-pc-bin grub-pc
sudo grub-install
sudo update-grub

Tu sort du chroot :

Code : Tout sélectionner

exit
umount -R /mnt

Redémarre l'ordinateur sans la clé de manière normale (tu devras peut-être forcé l'arrêt).
