Why am I getting this screen?

[HeLiOn]

I noticed this screen started popping up after I made the PC in question a dual boot system:

The motherboard is a GIGABYTE Aorus Gaming 7 rev 1.0, and the CPU is an Intel i7 8700K.
When I start the PC, after post, the AORUS loading screen is displayed for a few good settings;
Then this screen pops up, and then the AORUS loading screen is displayed again for like 2-3 seconds.
This happens even if I spam the F12 button from the very start. I can only enter the BIOS after this screen comes and goes away.
I went to the settings by pressing CTRL+S, to disable the prompt. I thought that deactivating the so call settings prompt, would disable it completely, but I was wrong
Now this prompt is displayed, but it simply doesn't show the third line.

it's trying to boot off the network, either because that is the first in the boot order, or because the things that come before it (disk, for example) dont have any suitable candidates.

That's your Intel NIC trying to boot from a network server.

 

Disable it as a boot option in your BIOS, or at the very least move it down the list so it has lower priority than your SSD.

OMG thank you guys so much. 
There was no such option in the boot order settings but I found the setting lower on the tab.
This was annoying, cause it increased the startup time by quite a bit. Thank you again.
