Peux-tu regarder dans le bios de ton micro

1) Remettre le mot de passe
2) regarder si tu trouves un onglet qui évoquerait la sécurité, si oui
3) serait-il possible de voir les fichiers dans le répertoire linux
4) et dire que bootx64.efi est autorisé à booter

Enter BIOS
Goto Tab ‘Security’
Goto ‘Set Supervisor Password’ and choose a password (this enables extra settings)
Go to ‘Select an UEFI file as trusted for executing‘ -> ‘EMMC‘ -> ‘EFI‘ -> ‘ubuntu’
and select a trusted file, ‘grubx64.efi‘.
Exit saving changes
Reboot

Je n'ai pas ça dans mon BIOS :

Je ne sais plus quoi penser.

La structure de grub.cfg est bonne

menuentry 'Ubuntu' --class ubuntu --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-b1533c85-a055-433d-a407-ca8772d1c866' {
	recordfail
	load_video
	gfxmode $linux_gfx_mode
	insmod gzio
	if [ x$grub_platform = xxen ]; then insmod xzio; insmod lzopio; fi
	insmod part_gpt
	insmod ext2
	if [ x$feature_platform_search_hint = xy ]; then
	  search --no-floppy --fs-uuid --set=root  b1533c85-a055-433d-a407-ca8772d1c866
	else
	  search --no-floppy --fs-uuid --set=root b1533c85-a055-433d-a407-ca8772d1c866
	fi
	linux	/boot/vmlinuz-5.3.0-40-generic root=UUID=b1533c85-a055-433d-a407-ca8772d1c866 ro  quiet splash $vt_handoff

}

Je viens de voir que shimx64.efi est présent dans /efi/ubuntu or hier il ne l'était pas
Accéde à la partition de boot EFI et modifie le fichier \EFI\refind\refind_x64.efi en \EFI\refind\refind_x64.ife
Cela devrait calmer et utilisons le fichier shim au lieu du fichier grub pour booter (je te laisse faire les montages)

cp  -v /media/efi/EFI/ubuntu/shimx64.efi    /media/efi/EFI/linux/bootx64.efi

Si rien ne change, vu le message secure, j'ai pensé que j'avais certainement commis une erreur dans la procédure CHROOT
Je te demande de la refaire. Le changement est le suivant: On installe la procédure signée comme l'aurait fait l'installation s'il y avait eu de la place dans la partition de boot.

Je vais bientôt me déconnecter . Suite demain pour ma part.

fazpedro

cp  -v /media/efi/EFI/ubuntu/shimx64.efi    /media/efi/EFI/linux/bootx64.efi

Cela fonctionne à nouveau !
Merci beaucoup geole !
