Hp laptop

Hello, my old computer I’m trying to fix got Corrupted some how and all I did was turn it on and this black screen popped up saying:

boot device not found

please install an operating system on your hard disk.  Hard disk (3F0)

F2 System diagnostics

for more information, please visit: [content removed]

but I can’t even get out of it to do anything.. what should I do?

Sounds like the hard drive has failed, or erased. Run the system diagnostics. Does the hard drive pass the test?

You can build a Windows 10 boot disk from another computer, and boot it up to repair.

If the hard drive is failed, it will need to be replaced.

Sadly it didn’t not pass the tests. And I can’t even get the laptop to the main loading screen..
