Secure boot violation into a boot device not found error

[Rushwj]

Whenever I turn secure boot on I get a secure boot violation and then I click submit and a boot device not found hard disk - (3F0) error. I have tried reflashing with a usb, redownloading bios f.24, resetting and putting default keys on. I am also on eufi and I’ve followed many YouTube tutorials trying to fix it and nothing works.

Greetings,

A UEFI Secure Boot error generally suggests unsigned code is attempting to run during a POST before the OS loads.

Is Windows and are all driver software up to date? Did you install any Legacy add-in MB components?

A 3F0 error indicates the OS is corrupted or the disk is failing.

Repeatedly tap "F2" at startup. Then check the PC's hardware using HP Hardware Diagnostics.

 Check Windows Security>Device Security>Secure Boot to verify the system's security certificates are up to date.

You should see the following if your PC is up to date:

 You could try removing the CR2032 MB battery, waiting for about five minutes, and reinstalling the CR2032 MB battery when the PC is disconnected from AC power to reset CMOS.
