I think the USB device address is not correct. Firstly the bootable isohybrid images must be copied onto the base device, not a partition device. So no "1" at the end. Further "/dev/sdbe" is not what i would expect for a USB stick. /dev/sdb or /dev/sde would be plausible. So try first whether /dev/sdb is really your USB stick by looking whether this read command lets it blink: dd if=/dev/sdb of=/dev/null If the desired USB stick reacted, then you can dare to overwrite it. # umount any mounted /dev/sdb* dd if=/var/tmp/above-filename of=/dev/sdb bs=4M; sync This will overwrite the partitioning of the USB stick. If any other valuable data are on it, make a backup first # umount any mounted /dev/sdb* dd if=/dev/sdb | gzip >"$HOME"/usb_sdb_backup.gz (To be restored by dd if="$HOME"/usb_sdb_backup.gz | gunzip >/dev/sdb which will bring back all partitions and their content. ) Debian's FAQ answer: https://www.debian.org/CD/faq/#write-usb ISOLINUX isohybrid wiki: http://www.syslinux.org/wiki/index.php/Isohybrid#Copying_onto_USB_stick_by_shell_commands In a neighboring thread there was the question whether bs=8m would be the right block size. Answer: It matters only for performance. The difference between bs=1 and bs=1M is noticable, the difference between 4M an 8M is not. Have a nice day :) Thomas
