I am using Lubuntul 12.04 on my PC. I want to install Ubuntu 12.04 on my laptop.
How do I create a bootable usb on Lubuntu so that I can install Ubuntu OS to my Laptop?
Use the Startup Disk creator. Install via Software Center or:
sudo apt-get install usb-creator-gtk
sudo fdisk -l
sudo dd if=/path/to/iso of=/dev/sdx
where /dev/sdx
corresponds to your usb. A comprehensive discussion (on Kubuntu) here that you might find helpful:
