No OS installed

[DomMT6]

Hi,  I think it is Windows 11.  I have an Envy 360 convertible.  I tried to use HP support, but it says my SN is invalid.  It is an older laptop.  The error I get is 3FO. Boot device not found install OS.  I did a drive check, it says Bios recovery files not found.  Failure in Drive 1, then a long error message. 6AJFVV-8ANC6R-GXGK6K-60A603. ID WOU47AV.  

I turned it on the other day and the screen is black with the above error message.

Hi @DomMT6,

Welcome to the HP Support Community. 

I'd be happy to help you! 

If the Hard Disk Error 3F0 boot device not found is displayed on a black screen, use the following procedures to try to resolve the error.

Restore BIOS default settings

To restore the BIOS default setting, open the BIOS Setup screen.

•  
• Turn off the computer and wait five seconds.
• Press the power button to start the computer and repeatedly press the f10 key to enter the BIOS setup menu.
• On the BIOS Setup screen, press f9 to select and load the BIOS Setup Default settings.
• Press f10 to Save and Exit.
• Use the arrow keys to select Yes, and then press Enter when asked Exit Saving Changes?
• Follow the prompts to restart your computer.
