I've downloaded the official Debian stable (Jessie) CD ISO and copied it directly to the USB (dd if=debian.iso of=/dev/sdd
). But motherboard failed to boot - the motherboard status LED display shows value 50
, which means some USB keyboard problem.

What worked for me - do not use ISO image as the USB image (even if it is recommended as the easiest way).
Use USB image (downloaded from http://ftp.cz.debian.org/debian/dists/stable/main/installer-amd64/current/images/hd-media/boot.img.gz):
# zcat boot.img.gz > /dev/sdX
Then mount it and copy ISO image to the USB filesystem:
$ cp debian-8.6.0-amd64-CD-1.iso /mnt/usb/
Now this USB drive will boot.
