Dualboot - Je n'ai plus le choix de mon OS au lancement ?

Void

Bonjour, j'ai Ubuntu 18.04 et W7 en dualboot depuis quelques mois, je n'ai jamais eu de soucis.

J'ai travaillé ce soir sous Ubuntu, j'ai ensuite voulu repassé sur W7 en rallumant mais je n'ai pas eu le choix au démarrage et on m'a directement lancé sur Ubuntu ?
Je me suis dit que c'était une erreur, j'ai éteint entièrement l'ordinateur, attendu quelques minutes puis relancé, rebelotte, directement Ubuntu, sans avoir le choix..
Première fois que j'ai ce problème et ça m'inquiète un peu, j'ai pas trouvé grand chose de similaire sur internet, je vous laisse un bootmenu ci dessous, si ca peu aidé..
Merci d'avance !

EDIT : J'ai l'impression que mon menu de démarrage habituel (lorsque je choisi Ubuntu ou W7 ne se charge pas complètement ?)
Au démarrage j'ai cette écran pendant plusieurs seconde, et ensuite le démarrage habituel de Ubuntu se lance. (Désolé pour la qualité de la photo).

=================== Suggested repair
The default repair of the Boot-Repair utility would reinstall the grub2 of sda5 into the MBR of sda.
Additional repair would be performed: unhide-bootmenu-10s   fix-windows-boot


=================== User settings
The settings chosen by the user will not act on the boot.

Bonjour

Avez vous essayé, dans un terminal depuis votre Ubuntu (qui si j'ai bien compris démarre noralement) les commandes suivantes :

sudo grub-install /dev/sda

puis :

sudo update-grub

pour tenter de recréer "Grub".

En général, c'est un problème d'affichage.

C'était en effet un problème avec le grub, je l'ai update et tout est rentré dans l'ordre, merci beaucoup !
