This article is a complete guide to using DBAN, explaining how to download the program to your computer, burn it to a bootable device, and erase all files.
Wipe Hard Drives with DBAN (Bootable USB)
Download the DBAN program. To begin, you need to download DBAN.
You can do this on the same computer you’re going to wipe or on a completely different one. However you do it, the goal is to download the ISO file and then burn it to a bootable device like a CD or flash drive.
Save the DBAN ISO file to your computer. When prompted to download DBAN to your computer, make sure to save it somewhere you can easily access it. Anywhere is fine, but keep a mental note of where.
