Empty boot menu list

[amdin]

Hey!

Just bought a new asus laptop s14 s431.

I was planning to use my sandisk disk on key to install windows 10.

I connected the DoK into the laptop and turned it on.

Bios is recognizing that both DoK and ssd are connected but the boot priority list is empty and so the boot menu.

 

I searched for this problem everywhere but couldn't find solution.

 

Please help me solve this problem.

 

Thank you.
