In my last article I detailed a discussion I had with my parents about using an Ubuntu Live USB Drive to do their banking. I realized that it may be helpful to show the steps involved in creating one. It doesn't take long at all. So as a follow up to my previous article "Banking With Live CDs", here's "How to Create a USB Live Drive for Banking"
A few notes before we get started. Older computers won't allow you to boot from a USB drive so you will have to use the CD method instead. For the Live CD visit http://www.ubuntu.com, download, burn and enjoy. Something else I've notice is older Dell computers may have issues with networking. There are fixes available, but they are beyond this article.
UNetbootin is the program that makes creating a USB Live Drive quick and simple. It allows you to create a USB key from which you can boot your computer with Ubuntu. To get started, point your browser to: http://unetbootin.sourceforge.net

This program allows for a lot of nice customizations, but we're going for a straight setup. Since I'm on my Windows computer (and I assume you are as well), download the Windows Version.

Insert an empty USB key into your computer and note the Drive letter Windows assigns it. Launch UNetbootin once it has finished downloading. In the left-hand dropdown, scroll to the bottom and select Ubuntu. The right-hand dropdown should automatically pick the latest version. At the bottom, select the drive letter of the USB drive. This will allow the tool to automatically download Ubuntu and install it to the selected USB drive.
Click OK. The tool will then start the process.
Depending on your internet connection speed it may take a while. For instance, my download took 20 minutes on a good sized cable modem.
Ok, the USB drive is ready. You should choose "Reboot Now" if you'd like to test your USB Live Drive.
Most computers have a method of selecting the medium to boot from. My Thinkpad uses F12. Holding the F12 key while booting brings up a menu.
Select the USB Drive you just created.
A few seconds later you will see the boot screen. Select Default and hit Enter.
In a few moments you will see the Ubuntu desktop. You can see that it immediately saw our wireless network and asked me if I would like to connect.
Since the all the files live on the USB disk the configuration changes you make should be saved.
You can now safely visit your bank online using the Firefox icon on the top menu bar without fear of the current generation of Malware that targets Windows computers.
(ONE NOTE OF CAUTION: After using the USB loaded with Ubuntu, be sure to check your computer's clock after restarting in Windows. There have been some incidences where the clock has reset after starting in Ubuntu. It's an easy "fix" in the Accessories.)
