BIOS recognize 1 out of 2 drives - No bootable device

[IgorOtenko]

I own an HP Pavilion Gaming Notebook - 15-ak100nj.
This model has 2 drives, 1 SSD which holds the operating system (Windows 10 64 bit) and the other one is a regular 1TB Hard Drive.
I decided to clean reset my pc and remove all existing files.
At first I tried the process and after choosing the "remove all files" in the in the "reset menu" the pc would restart and get stuck at 29% and go back to windows saying "Windows could not reset, no changes were made".
After few attempts I started getting a new error - "Boot device not found. Please install an operating system on your hard disk <3F0>".
After that error I went to check my BIOS settings and loaded system default, after that I got yet an other error - "No bootable device -- insert boot disk and press any key".
After that I ran I hard drive diagnostic on both SSD and HD and it came out as "Passed" meaning no issue with either of the drives.
When I go to "Boot Manager" I can se both of my drives, and when i choose the SSD which contains the OS, I keep getting the same error - "No bootable device -- insert boot disk and press any key".
When I go to - "Boot options" under system configuration in BIOS , and there to - "Notebook hard drive" under legacy boot order, I can see only my HD and not the SSD that contains my OS.
I assume that is the issue why I can boot my PC , but as i described nothing I tried helped the situation.
Maybe someone faced the same issue or have any idea how to resolve this one.
Since it is an original OS that came with the PC I want to try and save it instead of buying a new windows copy since the pc didn’t come with a recovery drive or CD.
