Quelle est la sortie du grub2-mkconfig ? Il détecte windows ?

Sinon pourquoi grub2-install sur nvme0n1p2 ?

Sinon, pourquoi pas grub2-install sur nvme0n1p2? C'est là qu'est installé mon windows!

GRUB_DISABLE_OS_PROBER=true ?

Non, je ne l'ai pas. Ca fait quoi? Voici son contenu:

GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="rd.driver.blacklist=nouveau modprobe.blacklist=nouveau nvid$
GRUB_DISABLE_RECOVERY="true"

Dois-je le rajouter?

Sinon, si vous connaissez une solution simple pour reinstaller windows 10, sans que je perde mon Fedora, je suis aussi preneur: je n'ai rien d'important sous windows!

Bon, j'ai resolu mon probleme, mais peut-etre pas de la maniere la plus elegante qui soit! J'ai simplement supprime mes 2 partitions windows, et reinstalle windows 10 a la place. Mes 2 boots sont maintenant detecte par l'UEFI de mon bios. Ca fonctionne tres bien.
Par contre, je crois que ca a fait saute mon menu Grub de Fedora, me presentant les dernieres version de kernel installees, mais je pense que je peux retablir ca facilement.

En tout cas, merci beaucoup pour l'aide.
