download the latest debian netinst .iso
wget http://cdimage.debian.org/debian-cd/7.1.0/amd64/iso-cd/debian-7.1.0-amd64-netinst.iso
copy the .iso to your lucky flash drive
dd if=debian-7.1.0-amd64-netinst.iso of=/dev/sd#
host the preseed in this directory
cd preseed/
python -m SimpleHTTPServer
meanwhile, boot from the flash drive, then at the splash page type
auto url=http://yourSimpleHTTPServer:8000/preseed.cfg
replacing yourSimpleHTTPServer with your hostname or IP address
