DBAN refuses to work

Why won’t DBAN (Dereks Boot and Nuke) work on my Asus laptop? I’m booting from the USB the DBAN is on, and I put the usb as the first thingy in the boot menu but when I click on it, it literally does nothing. Someone said something about a possible security system that stops DBAN from working on an Asus laptop/windows? Help please.
