My laptop doesn't have a UEFI BIOS but it's an interesting topic since I depend on bootable USB sticks in "emergencies". Can't imagine having a laptop without being able to boot normally from a USB device.....
Turns out the problem was with my Powered USB Hub. I have a number of peripherals connected, so the number of ports on my laptop just were not adequate. I now know if I want to boot to a flash drive or a CD/DVD, all I need do is change the boot mode from UEFI secure boot ON to Legacy secure boot OFF, ensure the USB and CD drives are before he hard drive in the BIOS boot order, then disconnect my USB Hub and my computer boots into the device I want just fine. I'll probably try a different USB Hub eventually, but I'm OK for now.
