can't create dual boot on dell laptop

hi to everyone...

i hope that i'm in the right place

I have Dell Inspiron n5110-6982, which I replaced his HDD to SSD, and installed the HDD instead of the CD-ROM

On the main hard disk (SSD) the OS is Windows 10 home 64 bit , as for the other hard disk, i split it and installed Fedora 25, however, i can't boot fedora, or to make primary OS

there is no options in bios menu that i can do in order to unable dual boot, and i'm not finding any options in windows to unable this dual boot

there must be a solution for such issue...

thanks on advance for any help
