I am trying to boot a Laptop with the American Megatrends BIOS from a different boot device.
The setup shows Boot option priorities "Windows Boot Manager" and "UEFI: Built-in EFI...".
There is also an "OS Slelect" (!) with the options "Windows" and "Linux".
But I did not find any option to boot from USB/CD/Lan.
What do I need to do?
