Hi, very new to Terminal commands and need a little help executing one. I'm trying to dual boot Ubuntu on my MacBook Pro using a USB device to start the initial boot / installation from. And here's where I got to on the ubuntu website:

sudo dd if=/path/to/downloaded.img of=/dev/diskN bs=1m
(replace /path/to/downloaded.img with the path where the image file is located; for example, ./ubuntu.img or ./ubuntu.dmg)

sudo dd if=/Users/liver/Desktop of=/dev/disk1 bs=1m

this comes up

To proceed, enter your password, or type Ctrl-C to abort.

Password:
dd: /Users/liver/Desktop: Is a directory
0+0 records in
0+0 records out
0 bytes transferred in 0.000028 secs (0 bytes/sec)


how do i customize the directory works?

sudo dd if=/path/to/downloaded.img of=/dev/diskN bs=1m

??
 
You need to have the path to the image, not just the path to the directory.
So, something like
sudo dd if=/Users/liver/Desktop/ubuntu.iso of=/dev/disk1 bs=1m

See the difference?
It may take a slight change to work on your particular setup.
