How to make a USB install/boot disk with Ubuntu 9.04

A USB  boot disk is a cool idea. It allows you to carry your favorite operating system in your pocket. Since  all modern PC provide USB boot from BIOS , you can use any computer and work on your on desktop. It is also possible to make data persistent. With ubuntu 9.04 Jaunty Jackalope  it is very easy to make an install disk.   Here is how you can do it.

Get hold of a USB disk which is large enough to hold ubuntu  and your data. I used a 2 GB Jetflash disk.  First, I partitioned it into two using gparted. Both were formatted to fat32 file system. See the figure below. ( You can also choose to install on a single partition).

Usb Drive Partiitions

Next click on System-> Admininstration -Create USB statrup disk. See the Screenshot below.


This will start the aplication unetbootin as shown below.


Click on other button and select the jaunty desktop iso image and then select the USB partition you want to install Ubuntu.

If you want to keep data persistent across  reboots you can check that  option and select the size for data block.  Unetbootin will create a single file named casper-rw on the flash drive and your home directory will be mounted in that file. It is a good idea to keep data persistent as you can walk into any Internet cafe and work with your data.

Click on Make startup disk and wait for some time, your USB boot/install disk is ready.
