h170m-ed3

hi,
I bought 3 GIGABYTE H170M-ED3 mobos, and I also used an INTEL I5-6400, 2.7 GHZ Processor, and a Kingston 8gb , 1600mhz memory. Although, I cannot boot via the onboard graphics, but only if i connect a pci Graphics card. I have the BIOS updated. Any help please?

It should go to the CPU graphics by default. But did you change it to that in the bios? Because by default it set to the 1st video slot.
