i've been working on my dads pc and tried to install windows 10 from an usb but the usb doesnt show up in the bios.
the hdd in the pc is empty and formatted and doesnt have an OS on it.
i already did some research and i dont have "legacy support" in this BIOS

amd fx6300
Gigabyte GA-78LMT-usb3
8gb ddr3 1600Mhz
corsair VS450 watt PSU

What can i do?

The windows you are installing is it new or from another computer? And did the program ask you for the activation code?

i put the windows setup on the usb from the orignal windows website , so it is a new windows. so i had no chance to insert an activation code yet
