This is genuinely hilarious.
A program called Darik’s Boot and Nuke has this 2 line description right at the top of the page:
Darik’s Boot and Nuke (“DBAN”) is a self-contained boot floppy 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.
Scarily, it then has this in it’s FREQUENTLY asked questions:
Q: Why does my computer start into a black screen after using DBAN?
A: You must reinstall an operating system because DBAN removes it.
