Windows 10 is gone after installing Fedora workstation 25

Hello everyone! I installed Fedora workstation on my Laptop a couple of moths ago. OK first of all let me start by stating the fact that I am a complete linux noob. The DVD that i used to install it wouldn't show up on my boot device list so i did it in "Legacy Mode"

The installation was done and good. But after i did a restart, windows 10 wouldn't appear on grub.

I started googling about this problem and found lots and lots of similer posts like this however none of them seemed REALLY SOLVED! Except one which said "Reinstall using UEFI mode and it will get fixed".

I did that. But guess what? It wasn't fixed. I kept trying and trying using the internet. Now I will show what I have done so far in my attempt to fix this problem

1. I have tried to edit the /etc/grub.d/40_custom file and manually entered a windows 10 boot entry which chainloads the bootmgfwr.efi file. It didn't work then I found out that the bootmgfwr.efi file wassn't actually present in the /boot/efi/EFI/fedora directory so i copied it from /dev/sda5/Windows/Boot . But it doesn't work anyway.

2. Then I tried to reset and reinstall grub2 using

rm /etc/grub.d/*
rm /etc/sysconfig/grub

yum reinstall grub2-efi shim

but after that, when i'm running grub2-mkconfig -o /boot/efi/EFI/redhat/grub.cfg

it gives me an error message

Generating grub configuration file ...
Script `/boot/grub2/grub.cfg.new' contains no commands and will do nothing
Syntax errors are detected in generated GRUB config file.
Ensure that there are no errors in /etc/default/grub
and /etc/grub.d/* files or please file a bug report with
/boot/grub2/grub.cfg.new file attached.

this is my parted -l
