Hello,
I just want to present a possible way of debian installation on usb stick or micro-SD card using debootstrap and how to boot debian. It'works very fine, even with a grafical xfce desktop connected over hdmi interface;-).
Maybe it's better way to do it. So it'would be great if could have some feedback or proposals for improvments!

#copy OS on USB stick or micro-SD

cd /usr/local/src/debian # cd into debian filesystem
cp -ax . /mnt/ # copy filesystem on to usb stick or mmc card
umount /dev/sdx
