Is sdb (ATA SanDisk SDSSDA24) a removable disk? no
Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub2 of
sdb1 into the MBRs of all disks (except live-disks and removable disks without OS).
Additional repair would be performed: unhide-bootmenu-10s
Final advice in case of suggested repair: ______________________________________
Please do not forget to make your BIOS boot on sdb (ATA SanDisk SDSSDA24) disk!
On peut voir que tu as la possibilité de sélectionner une entrée du menu Grub avec le noyau 5.4.0-58 et aussi une entrée de ce menu avec le noyau 5.4.0-62. As-tu essayé de démarrer sur l'une de ces entrées pour voir déjà si elles sont fonctionnelles et aussi pour voir si tu peux faire fonctionner VirtualBox dans ces conditions ou bien si c'est la même chose.
