[Résolu] Boot devenu très lent

Bonjour,

mon portable qui bootait en 15 secondes chrono, après des manip d'install d'un Windows (horreur!) et d'une Debian sur disque externe, boote maintenant très lentement. En faisant un démarrage recovery, je constate un problème de montage du disque sda et ensuite du sdb, 1mn30 chacun.
J'ai réinstallé GRUB par le menu recovery sans aucun changement; j'ai fait un boot-repair en live qui signale un problème.
Le rapport http://paste;ubuntu.org/p/nmbDZVfDFZ

En attendant si vous avez des idées...merci d'avance.

Bonsoir.
C'est pénible de devoir rectifier les liens.     Tu aurais pu regarder s'il était fonctionnel

Pour les idées, donne les retour de ces deux commandes

=================== Default settings of Boot Repair
The default repair of the Boot-Repair utility would reinstall the grub2 of sdb5 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
N'oubliez pas de régler votre BIOS pour qu'il amorce sur le disque sdb (ATA Crucial_CT240M50) !


=================== User settings
The settings chosen by the user will reinstall the grub2 of sdb5 into the MBR of sda.
Additional repair will be performed: unhide-bootmenu-10s
