Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would purge (in order to enable-lvm) and reinstall the grub2 of
mapper/ubuntu--vg-root into the MBR of sda.
Additional repair would be performed: unhide-bootmenu-10s
Je pense que geole est plus compétent que moi pour te conseiller.
