hi

You may need to replace both parts.
see this for boot error

3F0 boot device not found error displays on a black screen in Windows 10

HP Consumer Notebook PCs - Boot Device Not Found (3F0) or Automatic Repair Errors

If Legacy Support is ENABLED, change it to DISABLED, save the changes and exit,

If the computer does not restart, which is very likely, continue the procedure indicated.
In case of factory recovery, you risk losing all your personal data

If you are still under warranty, contact hp directly

You can try several things in order to try to recover your data

You can try a bootable cd / dvd type live cd (linux)

you can try removing the hard drive, in order to connect it to another computer internally, or with a usb adapter!

If your disk is not completely out of order, this gives you a small chance

I don't have the dismantling manual, if necessary let me know I can try to find it,
if too complicated, out of warranty, go to a computer repairer
