Product: HP ZBook 15 G3 Mobile Workstation

Please help!

After changing UEFI->LegacyBIOS(boot from USB)->UEFI, it's not possible to boot the laptop. 

The hard reset has no effect.

When powered on, lights including keyboard light are on, fans are working, but the screen is black.

No blinking of CAPS LOCK or NUM LOCK.

External display is not recognized and can't be used.

When boots with pressed ESC or F9, beeps, but nothing else happens.

When boots with Win+B pressed, the fans increase gradually the speed up to 100%. The screen remains black.

The screen itself should be ok, because worked properly before the described change.

Thanks in advance

Solved by connecting a monitor with VGA cable. HDMI was not recognized during boot.
