=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub2 of sda1 into the MBR of sda.
Additional repair would be performed: unhide-bootmenu-10s

=================== User settings
The settings chosen by the user will not act on the boot.

pardon de mettre le boot repair info comme ca....... je galere......
