Boot device not found - Hard disk (3F0)

Pavilion x360 Convertible 14-ba078TX
Microsoft Windows 10 (64-bit)


When I start my Notebook(Model - Pavilion x360 Convertible 14-ba078TX) , it says:

Boot Device not found

Please install an operating system on your hard disk. 

Hard Disk (3F0)


This happened when I tried to install an upgraded intel driver from intel's website(recommended by windows) and restart the system. 


I tried diagnosing the system by pressing the F2 button and for every test i.e., memory test, hard drive check(both quick and intensive), it passed.


Please let me know how I can resolve this.

Hi! @AshutoshVikramG,


Have you tried installing the operating system using the recovery discs?


Perform the following procedures to resolve this issue:

Procedure 1: Run diagnostics to rule out other hard drive issues.
Start or restart the computer.
Press F2 repeatedly during start up to enter the HP PC Hardware Diagnostics UEFI utility.
Select Component Tests > Hard Drive > Quick Test.
Select drive C:.
Click Run Once.
Once the test completes, results are displayed on screen. 

If the drive passes all tests, continue to Procedure 2. 

If the drive fails any of the tests, write down the failure ID (24-digit code) and contact HP Customer Support for further assistance.

Procedure 2: Ensure Legacy Support, under Boot Options, is DISABLED.
NOTE: If legacy boot support is enabled, you will NOT be able to see the Intel Optane entry as described in Procedure 3.
Start or restart the computer.
Press F10 repeatedly during start up to enter the BIOS configuration utility.
Check Legacy Support and disable if it is enabled: 

System Configuration > Boot Options > Legacy Support 


Boot Options > legacy Support

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