Por lo general siempre que he creado particiones las he creado con fdisk, pero bueno el fdisk ya no nos permite crear particiones tan grandes, otra por que en la chamba ya no quieren que usemos fdisk si no parted 😛 y a parte con formato gpt, ya no msdos para soporte de mbr 😛 bueno asi que veamos como crear una particion sencilla con parted
