I keep getting the error when I try to start up my hp notebook : Boot device not found please install an operating system on your hard disk. 

Hard Disk (3F0)

F2 system diagnostics 

Please someone help. I can't use my device anymore..

I don't mind if I'm going to lose my files and information. I just want to be able to use my laptop once again. Thanks in anticipation!

Hello @Obertee 

Welcome to the HP Support Community.

You get this message 3F0 because either of these:

• Computer's BIOS is not configured correctly and it tries to boot from a device (not standard HDD) that has no bootable stuff on it (e.g. empty USB pen drive)
• There is no HDD/SSD/storage drive present in the PC
• HDD/SSD is present but corrupted (or some connector is not working)
• Operating system (e.g. Windows) is totally corrup/unbootable

You can review the official HP article about such issues > http://support.hp.com/us-en/document/c01443463

• Based on your description, it looks like Windows issue, to me, but let's make further checks

Please, perform some basic hardware checks

1. Please, shutdown the computer using the power button

2. Power it on.

2.1 As soon as you press the power-on button, immediately begin hitting the Esc button (like tap-tap-tap).

This should open a HP Startup Menu

3. Choose F2 to open System Diagnostics (or the respective F option to run diagnostics).

Follow the on-screen instructions to perform System Test >> Quick test.

If there are no system checks/no quick tests, perform Run in test

or HDD (hard disk drive) and RAM (memory) check.

Let me know the test results.

4. Reset BIOS settings to default... Repeat steps 1-2 above but when HP Startup menu opens, please choose F10 to open BIOS setup.

Navigate through the BIOS and find the option to load default settings/configuration/reset BIOS settings to default.

Save the changes.

Exit the BIOS saving the changes.

Let me know how it goes.

If nothing helps, here is how to clean reinstall Windows 10 >> https://h30434.www3.hp.com/t5/Notebook-Operating-System-and-Recovery/EliteBook-very-slow-after-drive...
