Cannot find hard drive to boot

[KaciH]

Wondering if it sounds like my hard drive has failed. 
purchased the computer in 2018, but it’s been used for many many hours every single day

when I boot up my HP computer, a blue box comes up telling me “boot device not found please install an operating system”

computer was fine, just slow lately, then it shut down out of nowhere and when I tried turning it on again I got that message.

I ran a hardware diagnosis, my computer came with dual hard drives (an ssd where windows had been and an hdd for additional storage) and it scans 1 drive, the additional 1 tb one. When I go into bios and check the drives, the 1tb is the only one listed. 

I don’t know if a virus can do that, but I scan my computer a lot and hadn’t gotten any warnings ( I use malware bytes premium).  And, Wondering if it would be safe to get my stuff off the additional drive.

anyone have experience in this? Thank you for any advice/help!

@KaciH -- yes, your computer is showing the symptoms that your SSD has failed.

Wondering if it would be safe to get my stuff off the additional drive.

Absolutely.  Everything you saved to that disk-drive is 99.99% likely to be available.
