Is sdb (ATA WDC WD2500AVVS-6) a removable disk? no
Unmount sda1 from /media/ubuntu/1 To/ to avoid special characters (& or \ or space) incompatibilities
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 WDC WD2500AVVS-6) disk!
Cool j'apprends enfin que Ubuntu est sur le disque sdb et Win7 est sur sdc (sdd c'est la clé live).
Bon perso, c'est tout ce que j'en comprends. ; )
Et toi, vois-tu si ça répond au problème de grub initial :
error: unknown filesystem
