Darik's Boot and Nuke

Darik's Boot and Nuke ("DBAN") is a self-contained boot disk that securely wipes the hard disks of most computers. DBAN will automatically and completely delete the contents of any hard disk that it can detect, which makes it an appropriate utility for bulk or emergency data destruction.


DBAN is a means of ensuring due diligence in computer recycling, a way of preventing identity theft if you want to sell a computer, and a good way to totally clean a Microsoft Windows installation of viruses and spyware. DBAN prevents or thoroughly hinders all known techniques of hard disk forensic analysis.

DBAN is a free software product that can be used at home or in a business at zero cost. The only official place to obtain DBAN is by download at this web site. We do not sell DBAN media

We recommend CDBurnerXP for burning the DBAN boot media. Read the CDBurnerXP ISO burning tutorial for step-by-step instructions.
Almost every burning program will burn the DBAN boot media correctly with default burning options. Just double-click the ISO file.
We will ask that you try CDBurnerXP if you have any problems with CD-R or DVD-R boot media. You can get help from us for CDBurnerXP, but we don't usually provide support for other products.
CD-ROM drives manufactured before 1999 cannot reliably read burned media.
DBAN has been burned incorrectly if you see just one file on the drive when you open the CD-R or DVD-R in My Computer or Windows Explorer.
DBAN may not boot if you modify the ISO file or filesystem layout in any way, like by injecting files. Any change to the syslinux.cfg file requires ISO remastering.
