How to run and install Ubuntu from a live usb drive
|Running and installing from USB|
Setting up the bios firstIf you are booting from a DVD you will probably not have to make any of these changes that I will discuss. Most computers with DVD-players will have the DVD-player set as the first boot device. This means that every time you turn on your computer it will look first for a boot loader on the DVD player. If none is found it will check your hard drive and it will boot from there. Checking the usb drive for a boot loader will usually be disabled as usb drive have a higher risk of transmitting viruses that install at boot time, etc. Therefore, in order to boot from the USB stick you have created, you will enable this in the bios settings of your computer.
Explanations of terms usedEvery manufacturer has a slightly different bios. I will show you how I go into the bios of one of my laptops, an Asus eeePC, and set it up for enabling the usb for booting as the second boot device. At boot time I can choose the desired boot device by keeping the ESC-key pressed.
Bios; The first piece of software that runs on your computer and which initiates all hardware.
Boot loader: Software that initiates the loading of the operating systems.
On my Asus I need to press the F2-key at boot in order to access the bios-setup menu. Your bios will probably output a message at the bottom of the screen at the beginning of the boot sequence, which tells you what button you need to press to access the setup menu.
|Pressing F2 at boot time|
I use the arrow and enter key to navigate to the Boot tab.
There I move down into the Boot Device Proirity settings. At the second boot device I press enter and I select Removable Dev. and press enter again.
To exit the Bios Setup Utility I keep pressing escape until I see below exit screen, where it says: "Save configuration changes and exit now?". I press enter for OK.
And I am done. The machine will reboot again as normal.
Booting Ubuntu live
Now I plug the Ubuntu Live Usb Stick into one of the available usb ports. I reboot the machine and at boot time I keep the escape key pressed. This will start the boot device selector.
Here I will select the usb drive as the desired boot device. And the laptop is booting from the usb stick as you can see by the Ubuntu Live bootscreen.
Running Ubuntu liveOnce the system is loaded you will be presented with below screen, where you can choose to run Ubuntu live or to install Ubuntu on you system. I suggest you try Ubuntu live first to see what it is like. If you then want to install it, you can still do so from the live environment, as you will see later.

Installing Ubuntu from the live usb driveYou can install Ubuntu to your hard drive right from the live Ubuntu desktop. Simply double click the desktop icon named "Install Ubuntu ...". That will start the installation process described below.
First you will be able to select the language that will be used in the installation process. After the install you can install other than English or the one you select here.
|Choose your language|
- Download updates while installing
- Install this third-party software
This will make sure your system is up to date immediately after the install. It will also install support for (some) proprietary media codec like mp3 and mp4.

The layout of your keyboard has already been detected, but it is good to type something here with your language special characters and see if everything works.

Here you will set up your user account and you can opt to have your home folder encrypted. If you choose to do so, then you cannot 'Log in automatically' as your user password is used to decrypt your home folder every time you log in.
