Voila c'est un peu long! Pour le boot-repair je regarde et je te redis d'ici une heure! Merci de m'aider

Re,

L'erreur me semble être dans 40_custom.

Tu devrais essayer de remplacer set root=(hd0,3) par set root=(hd0,2) dans le fichier 40_custom. Le fichier bootmgr.exe doit en toute logique s'y trouver puisque c'est la partition active (elle porte le fanion boot : c'est donc elle qui a les fichiers de démarrage).

Un

sudo update grub

pour finaliser la modif. Vire aussi ton fichier 08_perso~ qui me semble inutile.
