SSD detected on my Windows but not detected on BIOS boot

My Notebook had problem with boot priority. So I have HDD on main port and I just added SSD for my second port (replace my CD/DVD drive). I had problem with my main port so i cant replace it for SSD. my SSD : Samsung 850 EVO and I already migrate it using samsung Migration. So i had 2 windows on my HDD and my SSD. but windows still run on my HDD not my SSD. I try change some setting on boot priority.. but i dont see my SSD on there...

NB:

1. SATA setting = AHCI

2. Main HDD = HDD (WD something), SATA ODD = my SSD (Samsung SSD)

3. I cant upgrade my BIOS (I think it's already up to date) (Im using Dell N4110 Inspiron and BIOS ver A12)

4. I already unplug my main HDD but it cant boot so i can't run windows on my SSD

5. SSD detected on windows and Bios (SATA ODD= Samsung) but not my boot priority

what should i do?
