Grabar ISO en USB booteable en GNU/Linux

Primero obtener la partición donde está montado el USB con el comando fdisk -l

#fdisk -l | grep /dev/sd

Ejemplificando, que esté montado en el /dev/sdc1, proceder a desmontar la unidad con umount

#umount /dev/sdc1

*Paso opcional: Formatear la unidad con la unidad mkdosfs

#mkdosfs -n 'USBname' -I /dev/sdc -F 32

Buscar el iso que se quiero montar y prepararlo con el comando isohybrid (¿No está presente?)

#isohybrid imagenLinux.iso

Copiar el iso al USB con el comando dd. Percatarse que en la sección if= se coloca la ubicación del iso que se desea grabar al USB. En la sección of= es el destino, para este caso el disco USB. También notar que no se está colocando /dev/sdc1 sino /dev/sdc

#dd if=imagenLinux.iso of=/dev/sdc bs=4k

Finalizar sincronizando la información en caché al disco y expulsar la unidad con los comandos sync y eject respectivamente

#sync
#eject /dev/sdc

Para instalar isohybrid

#add-apt-repository ppa:mkusb/ppa
#apt-get update
#apt-get install syslinux-utils
