I downloaded DBAN iso file and also downloaded rufus to make a bootable lexar flash drive, I selected DBAN iso file and click on START to create a bootable flash drive, its all good, however, when I restart my pc and I go to the boot tab in the BIOS, I select lexar partition 1, press enter and all that happens is the screen flickers and nothing happens, all it does is just a flicker and thats it. any idea what might be happening that I can't boot the flash drive for DBAN? Thanks in advance.
