Hi Matthew,
This is Wil, one of the independent advisor, an expert with Windows 10 and a fellow Windows 10 user like you. I understand your concern about the Dban boot and nuke system requirements.
DBAN is an open-source application. You would actually need to create a bootable media for it by downloading the ISO file from the DBAN page and boot your computer using it.
I hope the information I provided helps you. If you need further assistance please do reply back and I will respond as quickly as possible. Have a nice day.
Thanks,
Wilfred P.
Independent Advisor
