How to make a bootable usb from within linux, and manjro question

Got zorin on my lappy right now, wanna put manjaro on it so I got the iso. Problem is I've only made linux usbs in windows with linux live usb, I'd like to just use my zorin install to make it this time.

 

Also I have an nvidia gpu with optimus, so far I just install bumbleebee and call it good but I've heard arch and arch distros do things differently for optimus cards.  What exactly is different and what do I have to do to get it working?

 

 

UNetbootin is a good app for a live usb

http://unetbootin.sourceforge.net/  been doing the distro roll myself.

dd if=manjaro.iso of=/dev/myusbdrive bs=32M ; sync

is how I always do it

i have issues with unetbootin in arch. so i use dd to make the boot drive. 

not sure on the graphics.

 [edit] just don't dd the wrong drive [/edit]
