Hi, I used to have Windows + Linux Mint in dualboot, but now I decided to install Fedora instead of Mint. I have Windows installed for about a month and now I finally have the time to Install fedora. However, the Windows 10 does not appear in grub.

What I already tried:

But it didn't helped.

Output of grzb2-mkconfig

[ajezek@localhost ~]$ sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
