Windows 10: no hard disk detected after blue screen

I use Windows 10 as an operating system on Lenovo ideapad 320.
this morning while using Firefox browser, I received the microsoft blue screen that I actually forgot what it said then the PC restarted automatically and I got this screen in the picture. I connected the computer to internet via an Ethernet cable and I got the screen in the second picture. I noticed in the BIOS configuration that the hard disk was not detected as it's shown in the picture below. I'd like to know what caused this problem and how can I fix it without formatting the PC as I have really important data in it.
