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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1870579 Title: System can't find OS to boot after install with UEFI over Windows 10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1870579/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
