Can't install driveles system from USB memory stick: ISO not found.

[Johannes Graumann <johannes_graumann@web.de>]

Hi,

I'm trying to install a driveles system via an USB memory stick like so:

- get 
http://http.us.debian.org/debian/dists/unstable/main/installer-i386/current/images/hd-media/boot.img.gz
-get
http://http.us.debian.org/debian/dists/unstable/main/installer-i386/current/images/netboot/mini.iso
- check by udevmonitor where memorystick ends up (/dev/sdd)
- zcat boot.img.gz > /dev/sdd
- mount /dev/sdd /mnt/dummy
- cp mini.iso /mnt/dummy/
- umount /mnt/dummy
- boot into diskles system, make bios treat usb devices like harddrives
- reboot and boot from usb memory stick
- pass language selection, keyboard layout and scan for hard disks in
installer

This always fails to find the mini.iso

What may I be doing wrong?

Thanks for any hints, Joh
