Installation HELP!!!!!!

I am trying to install Linpus Lite 9.4 by following the instructions below - However, as soon as I type in /sbin/fdisk /dev/hda or /sbin/fdisk /dev/sda I keep getting errors saying unable to open /dev/sda etc.......

Who wants to install linpux linux lite on a USB-Pendrive or on a SATA harddisk, has to replace "hda" with "sda" and "hda1" with "sda1".
