When you removed the old SSD from the machine, it didn't have any other boot device so it defaulted to Network boot.  Rebooted to BIOS > General > Boot Sequence : You should will have to set either Samsung drive or windows boot manager as first boot priority    
First of all, pardon my english, it isnt my main language. Now for the problem: I recently changed my SSD in my Inspiron 7567 (I7-7700hq and GTX 1050ti variant), from the original SSD that came with to a Samsung EVO 980, but when i start it up it gives me the errror "Intel UNDI, PXE-2.1 (build 083) Copyright (C) 1997-2000 Intel Corporation", then a check error failed and starts normally, dont get me wrong, the SSD is super fast, but i get that error each time it turns on, thank you all for the help!.
Changed SSD now i have Intel UNDI ERROR
