Hi, welcome to Fedora. It sounds like you may need to regenerate your grub config. Depending on whether you installed Fedora using EFI or not, the command to do this will be slightly different. The easiest way to determine this is check if there's an 'efi' folder in the /boot directory ls /boot. If you have the efi folder in /boot, you should run the command grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg if you don't have the efi folder, the command you should run is grub2-mkconfig /boot/grub2/grub.cfg

@t3rm1n4l I'm not in EFI and I have efi folder in /boot, the best way to do this is -> how-to-know-if-im-booting-using-uefi

HI, I follow your instructions, and the os probe find window 10 but when I restart it boot directly to Fedora, don't show the bootloader to make selection of Windows 10.

I'd like to see the grub.cfg. One way to put it up somewhere (expires in 7 days) is:

cat /boot/efi/EFI/fedora/grub.cfg | fpaste

And this command will show boot entries and order:

efibootmgr | fpaste

Just post the URL for those two commands and we'll see if that reveals anything.
