UEFI Booting ISSUE

I made a password reset disk to remove the password added by my kids at my home computer. But the computer can't boot from the USB even set it as the first device. I heard it is the issue of UEFI BIOS? How to let the computer booting from external USB? It is MSI motherboard. thanks

I don't know how you did it, but I've had problems like this.i just created a UEFI bootable disk with USB ,but my computer can successfully boot from USB.telling me how do you burn and set the first boot? maybe the ophcrack is a free tools ,but it doesn't mean it can help you complete the task.
