Back up your important files to a blank CD or a flash drive. You can also use Dropbox or a similar cloud-based service to upload your files for backup.
Download the DBAN program from SourceForge. DBAN is designed to delete all files from a drive no matter the type or format.
Download PowerISO or a similar ISO burning software. Follow the instructions to install the program, and launch it after installation.
Insert a blank CD into the computer disc tray, or plug in a flash drive to a USB port. Mount the DBAN image in the ISO program, and burn it to the disc or flash drive. Do not just extract DBAN to a flash drive.
Open DBAN using the flash drive or the new CD. Once the main menu appears, follow the on-screen prompts to wipe the hard drive.
