Suggested repair: ______________________________________________________________
The default repair of the Boot-Repair utility would restore the [(generic mbr)] MBR in sda, and make it boot on sda1.
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix
La session live est bien démarrée en mode Legacy :
===================================== UEFI =====================================
This live-session is not in EFI-mode.
C'est tout bon pour lancer l'installation. Tu peux déconnecter le disque Windows si tu veux mais je pense que c'est inutile parce que les deux disques durs sont bien détectés. Donc l'installateur te demandera sur lequel faire l'installation. Mais si tu préfères bétonner, c'est toi qui vois.
