Boot device not found

[Gamerboi610]

I got this computer in 2018. One day it stopped working and when i loaded it back up it left me with “boot device not found. Please install an operating system on your hard disk” and it says hard disk 3FO. Please help me, i’ve tried everything. Same thing happened to the the exact computer that one of my friends has. And i tried the BIOS default thing and nothing. It wont even let me run a storage test. If i click on it it stays for a second and dissapears.

edit: The computer is HP Stream 5MP95UA 14 inch Laptop Intel N3060 4GB 32GB eMMC Windows 10 S - Blue

Sadly i’ve tried everything and nothing is working. Im very confused on the storage teats however. Reason being that whenever i try a quick or extensive it runs for a second and just stops and brings me back to the diagnostic’s front page.  Memory test works, just not the storage tests.

I tried both storage tests and when I tried to start them and brought me back to the page I had previously been on. So could that mean something’s wrong with the storage?
