Install DBAN on a USB flash drive using unetbootin

Mount USB, then replace every occurrence of ubninit with ISOLINUX.BIN in the syslinux.cfg file

sed -i 's/ubninit/ISOLINUX.BIN/g' syslinux.cfg

Replace every occurrence of ubnkern with DBAN.BZI in the syslinux.cfg file

sed -i 's/ubnkern/DBAN.BZI/g' syslinux.cfg

Your bootable DBAN usb stick is ready now.

Note: DBAN will boot up and data erasing will start within 10 seconds without any prompt
