My problem is very much like @tobia described, I make some changes in the bios (like disabling secure boot or enabling legacy mode) press Save and exit then the computer reboots and bios settings go back to default.
I guess that the reason why @tobia doesn't see the USB drive listed in the boot options is because he cant disable secure boot.
And I dont see any blank screen, the boot process seems pretty normal.

Im sorry i dont really know what lenovo is doing. As far as I know I didnt do any bios upgrades.
