Envy 360 / Code 3F0 Please install an operating system on your hard drive

[LAK2020]

My Envy x360 will not boot up.  It displays the message "Boot Device Not Found"  / "Please install an operating system on your hard drive"  / Hard Disk (3F0).

@LAK2020 Did you perform a hard reset to release all excessive static from the PC (this should get your keyboard working again, if it doesn't, please try with an external keyboard),

or Run a hardware test to identify the issue?

While you respond to that, please follow the below steps to identify and resolve this concern:

Step 1: Perform a hard reset

HP Notebook PCs - Performing a Hard Reset or Forced Reset

Step 2: Restore BIOS default setting

Step 3: Test the hard drive using HP PC Hardware Diagnostics UEFI

Step 4: Reseat the hard drive (here's a video that shows how to re-seat the drive: Click here)

Step 5: If the tests pass, Perform an HP System Recovery

(If none of the above actions resolved the error condition, back up your personal data) and then perform an HP System Recovery on the notebook:

Thank you for the message.  I disconnected the battery and plugged it back in and still have he same error.  The hard disk check passed.  Any other suggestions?  Thank you.

@LAK2020 Did you perform the system recovery as well? to reinstall the OS, since the h/w test passed? if not, Click here for instructions.

And if that doesn't work, you may need to order the recovery media from HP if you haven't created one on your own or check if you can get it from the HP cloud.
