Is sdb a removable disk? no
Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would purge (in order to unsign) and reinstall the grub2 of
sdb5 into the MBRs of all disks (except live-disks and removable disks without OS).
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your BIOS boot on sdb disk!
La partie "parted -lm" de ce Boot-info semble vide.
Je te prie de passer la commande suivante dans un terminal :
sudo parted -lm
et de coller le résultat complet (*) de cette commande dans ta réponse.
EDIT : passe aussi la commande suivante (ça fait chier les résultats filtrés qu'on a dans le Boot-info) :
sudo fdisk -l
Et colle aussi le retour complet (*) dans ta réponse.
