Thank you for posting on the HP Support Community.

The 3f0 error code indicates an issue with the HDD-Hard Drive. I appreciate your efforts to try and resolve the issue.

I’d like additional information in order to troubleshoot: 

• Did this happen after a recent window or software update?
• Are you able to boot into windows desktop? 
• What is the operating system?

While you respond to that, I recommend you perform the following steps to isolate the issue and arrive at a fix:

Firstly, let's perform a hard reset:

Hard Reset:

1) Shutdown the computer.  

2) Unplug all the Adapter and peripherals connected.  

3) Remove the Battery. ( not for Built-in Battery computer ) 

4) Press and hold down the power button for 15 to 20 seconds.  

5) Plug-in the Adapter and put the Battery back into the computer if it's a (removable battery)

6) Try to turn on the computer and check, If the issue persists continue next step

Set BIOS default and restart:

1. Restart your notebook.
2. During startup, press F10 repeatedly until the BIOS menu is displayed.
3. Once the BIOS menu is displayed, press F9 to restore factory defaults.
4. Select Yes to confirm.
5. Press F10 to save changes and exit.
6. Select Yes to confirm.
7. The computer restarts using the default settings. 

If it continues then the computer may need to be serviced as it may be a hardware issue with the unit.

Keep me posted for further assistance.
