this is very hard to read. So you installed win 10 first then fedora. When you boot and choose win 10 ? what happens? what fedora version you installed?

The partitioning clearly indicates this is a UEFI installation of Windows, and a BIOS installation of Fedora; and also the fact efibootmgr says what it says also indicates this. What you've likely done is changed the firmware setup to "disable UEFI" or "enable legacy" support. You'll need to change the firmware settings back the way they were, and reinstall Fedora. Delete these partitions when given the opportunity.
