Dual boot Ubuntu mate/mac os X ne fonctionne plus

Bonjour,
Depuis une mise à jour, le dual boot avec Refind ne fonctionne plus. J'ai sans aucun doute commis une erreur en voulant réinstaller Grub. J'ai utilisé boot repair, qui envoie un message d'erreur concernant la réparation. C'est un peu comme si Mac n'était plus reconnu et qu'il y ait plusieurs type de Grub.
Voici ce que donnait le rapport d'info de boot repair :

   File system:       vfat
    Boot sector type:  Unknown
    Boot sector info:  According to the info in the boot sector, sda1 starts
                       at sector 0. But according to the info from fdisk,
                       sda1 starts at sector 40.
    Operating System: 
    Boot files:        /EFI/ubuntu/grub.cfg /EFI/Boot/bootx64.efi
                       /EFI/refind/refind_x64.efi /EFI/tools/gptsync_x64.efi
                       /EFI/ubuntu/fwupx64.efi /EFI/ubuntu/grubx64.efi
                       /EFI/ubuntu/grubx64.efi.ANCIEN /EFI/ubuntu/mmx64.efi
                       /EFI/ubuntu/shimx64.efi
                       /EFI/refind/drivers/btrfs_x64.efi

J'ai aussi créé un rapport lors de la tentative de réparation, mais il semble que le fichier n'existe pas ?

Merci !

Re : Dual boot Ubuntu mate/mac os X ne fonctionne plus

Salut, arrive-tu a démarrer sur un système ou ça ne marche pas ? Car tu pourrais essayer les commandes grub genre : sudo update-grub ou d'autre. Mon ubuntu en 18.04 en mode console m'avais proposé une commande qui je ne sais pas si elle a effet sur grub : sudo repair ---broken_files je crois après je sais pas si c'est ça.
