Ubuntu

You will need 2 different USB 3.0 drives for this class.

A minium of an 8GB USB for the installation medium, extra is unnecessary in this case.
16GB or larger USB to hold the OS after it is installed.

Make sure your drives are USB 3.0, as the speed of a USB 2.0 is way to slow.

Follow steps 1 to 3 of this guide by 2/9, to create a bootable USB. Prepare this before class.

If you like, try step 4 to boot from the USB and select to Try Ubuntu.

We will do the actual installation in class.

If you have a laptop, you can use VirtualBox and do away with the USBs if you prefer. This will setup a virtual machine within your computer. Or if you like, you can actually install from the ISO image inside a virutal machine to a real USB and then boot from the USB afterwards. I can explain this in the lab, if you are curious.
