I just installed a Samsung 960 Evo as my boot drive but now my hard drives won't show up in bios or in windows

When the 960 isn't plugged in I can still boot to my HDD's and they are working perfectly

I should also add it doesn't come up as unidentified in administritive tools either
 
Solution
Try moving the HDDs to different ports. Check the board's manual and see if some SATA ports get disabled when using a m.2. Identify them and use different ones.
