Darik’s Boot and Nuke – Modifed for no prompting and quick wipe under Win7(32/64)
As as stated in the docs, a person cannot simply edit isolinux.cfg and re-save the iso using PowerISO or similar iso editor. You must re-master the iso. Here’s how to accomplish it.
make a directory for yourself to do the work as well as a directory for the orig dban files.
extract dban* (from http://sourceforge.net/projects/dban/) to c:\tmp\img\
To have the cd autostart with no prompting and set my wipe preference I edited (via notepad) ISOLINUX.CFG and changed:
PROMPT 1 -> PROMPT 0
DEFAULT dban -> DEFAULT quick
extract mkisofs.exe and cygwin1.dll from ftp://ftp.berlios.de/pub/cdrecord/alpha/win32/cdrtools-1.11a12-win32-bin.zip to \tmp\
via a cmd prompt: (the mkiofs stuff is CaSe SenSiTive)
mkisofs.exe -R -o DBAN-2.2.AutoBoot-1Pass0Erase_i586.iso -b ISOLINUX.BIN -c ISOLINUX.CAT -no-emul-boot -boot-load-size 4 -boot-info-table c:\tmp\img
Burn the resulting iso (DBAN-2.2.AutoBoot-1Pass0Erase_i586.iso) via ImgBurn (http://www.imgburn.com/) or similar.
If you wish, you can also use one of several USB bootdisk creators to burn the iso to a thumbdrive. I used Universal usb Installer @ http://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3/
When using Universal USB Installer and selecting DBAN from the dropdown list of images, it looks for filename in a named pattern which is why I chose the ISO name I did when creating the new iso.
