Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would reinstall the grub2 of
sda1 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 sda (ATA WDC WD5000LPCX-7) disk!

Quand j'ai lu " il ne trouve plus le disque dur de démarrage" dans ton post #1, j'ai supposé que tu ne parvenais plus à démarrer sur ton Ubuntu. Mais ce n'est pas le cas. Est-ce que tu as toujours ce problème ? Si oui, explique mieux la chose parce que pour moi tout baigne dans ce Boot-info.
