I recently bought a new computer, but I'm not very good at building so I ordered parts and got a Umart to make it for me, they said that they installed windows. I have two internal drives, one Samsung SSD 850 evo 500gb and a HP envy 5530 series 1.0 (2tb i think). I just booted for the first time, and it said select media store or boot media storage with the OS on it. I entered the UEFI and my 'boot option priorities' goes as
1.Hard drive
2.Samsung SSD
3.HP Envy
I'm not sure what to do from here, so if someone can help! Thanks :)
EDIT: Exact error shows:
Reboot and Select proper Boot device
or Insert Boot Media in selected Boot Device and press a key
