Salut,  
J’ai Debian Buster installé en DualBoot avec Win7  
J’ai installé Grub-customizer (l’erreur), et je l’ai configuré pour que Win 7 démarre par défaut au bout de 10 sec.  
Problème: Sur l’écran de Grub, je ne vois pas Win7 et ça boote sur Debian.  
Voici mon fichier Grub, si vous pouvez me dire où ça cafouille, j’en serais bien content 🙂

```
 # If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'

GRUB_TIMEOUT="10"
GRUB_DISTRIBUTOR="Debian"
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID=ed5ffa5f-f36d-4cdc-a5a1-aa6d0496a633"
GRUB_CMDLINE_LINUX=""

C’est le contenu du fichier /boot/grub/grub.cfg qu’il faut regarder.  
S’il ne contient pas d’entrée de menu pour Windows dans la section 30\_os-prober, il faut exécuter `os-prober` pour voir si Windows est détecté. Si oui, exécuter `update-grub` pour reconstruire grub.cfg. Si non, installer le paquet boot-info-script, exécuter `bootinfoscript` et examiner le rapport.

Edit : avec `GRUB_DISABLE_OS_PROBER="true"`, Windows ne risque pas d’être détecté.

Win 7 est bien détecté et j’ai déjà fait un update-grub sans effet  
Le update-grub donne:

```

La dernière ligne dans /etc/default/grub désactive la détection des autres OS par GRUB. Commente-la et refais update-grub.

Ok, je pense que tu as trouvé: j’ai commenté la ligne, updaté et j’ai maintenant win7 qui apparait dans la liste. Je vais rebooter et je reviens dans 5 min.
