@okanb3 Well i made it. Here is my solution;
I just change the /etc/grub.d/40_custom file to my needs like this.
And then grub-mkconfig -o /boot/grub/grub.cfg to make changes. After that i can successfully reboot into windows.
PS. In the file “set root=(hd1,gpt2)” means SDB2. My EFI partition was there so i changed this to fit my needs. You need to this to your specific configuration.
