I installed focal on a third HP laptop and got the same results.
This Laptop had Win 10 installed on it and after a full install of Focal, I removed the USB key press Enter and system would not boot again.
It would say could not find OS
Then after Pressing F9 to choose boot device and selecting Ubuntu as default boot it would work.
