Diskpart : there are no fixed disks to show.. Factory reset gone awful

Hi everyone, I was asked to factory reset an Asus laptop and install a win 7 on it, while starting to install the win 7 I got stuck with the "no device drivers were found", searched for some tutorial on YouTube, found this vid: , followed the command codes step by step on MS-DOS : ( Diskpart >>> list disk >>> select disk 0 >>>> Clean >>>> create partition primary >>>> format fs=ntfs quick) and now I completely lost the disk 0 with all system files, no hard drive showing as a boot option in the BIOS. Am I screwed ? Is there a way to create or reactivate the internal HDD ?? Thank you in advance for your help

 

Why did the startup window get cleared?

I didn't missed any step, the list was gone and gone , even after using lot of programs the programs were not listed in that list.
