NO BOOTABLE DEVICE FOUND

I have bought this device a few months ago and already have submitted once to the dell for some hard drive issues. Now again a new problem is showing: No bootable devices found (in Dell Supportassist).

I can not run installed windows and not even find any drive to reinstall new copy of windows. Can I get rid of this problem? its very annoying to submit my laptop again to company cause it requires much time to get back again. Here is some specification:

Product Name: Inspiron 3558

System BIOS: A12

Service Tag: 6VNH0C2

ePSA: Build 4302.10 UEFI ROM

Please give me a solution soon.

Thank you.
