I had some real problems getting dban on a bootable cd, at one point it finally did boot then just hung. I just booted back into safe mode and pulled an extra network driver. Still not a happy camper.
Since it is a crappy day I may take another try at making a new dban disk. I was using the lap top burner which took a couple shots to get a good disk out of. I still have a few blanks. Will have to see what is on the wifes computer for a burner and software.
Did you ever use a boot flash drive? I am pretty sure I can set bios for removables on that rig.
No, never tried to boot from a flash drive. That might be worth a try
