Now we have a number of options when it comes to installing tails.

The easiest is to install it as a virtual machine with this option.

You're going to first of all install a virtualization software such as virtual box or VM where inside

your current operating system whether it's Linux Windows or OS X and then you'll install tales as a

virtual machine.

Using this virtualization software so you won't have to restart you won't have to reboot in order to

start tales.

You'll be able to started within your operating system within Windows or Linux or OS X and you won't

need the USB stick or a DVD to started the problems with this is tails will lose most of its benefits

when it's installed like this.

Because like I said Thales is designed to be alive operating system one of the main advantages of it

is the fact that it's amnesiac.

So when you use it on a computer and turn off that computer it leaves no traces.

So even if that computer is inspected they won't even know that this computer was used to run tails

when tails is installed as a virtual machine.

It's going to share the resources with your host operating system with Windows Linux or OS X.

This means that it will leave traces of it being used.

You also want to be able to have a USB stick that you can use on any computer.

You'll only be able to use tools within that computer that you installed the virtual machine on.

And because Thales is installed on Windows the next or OS X like we said before these operating systems

collect data about you.

Not only that they also have a number of programs that collect data about you.

All of these programs access the Internet directly not through the Tor network and all of these programs

and operating systems could be vulnerable to code execution or buffer overflows which can be used to

hack into your computer.

And again from there the anonymous you therefore install entails as a virtual machine is not great because

it will basically lose a lot of its advantages and a lot of its great features the second option which

is better is to install tables on a DVD and then use that DVD to boot.

Tails so you can use the DVD on any computer regardless of what operating system it runs.

All you have to do is just put the DVD and restart the computer boot from the DVD and then you'll be

able to use tails.

Now with this tells will come with all of its great features so it'll be life.

It'll leave no traces and it'll be running natively so it won't be sharing resources.

Therefore you won't really need to worry about leaks or about other programs collecting data or any

of the other stuff that we have to take into consideration when we're running the tour browser or when

we're running tails as a virtual machine.

The only disadvantage to this method is the size of the DVD it's a little bit big and the installation

of tails will not be persistent.

What I mean by that is if you store any files while you're using tails you will lose them.

Once you turn off the computer or restarted the third option which is the best in my opinion is using

a USB stick.

So this comes with all of the benefits of the DVD.

We're going to install tails on a USB stick and then all you'll have to do is connect that USB stick

to any computer regardless of what operating system it runs.

Restart that computer and you'll be able to boot into tails.

Tails will run in its live mode again.

It won't use any resources if you turn off that computer.

There will be no traces on that computer and we can also configure this installation to be persistent.

This means that we can actually use part of the US b storage as storage for tails so you can actually

save files within your current installation within the USB stick and when you turn off the computer

there still be no traces.

But even if you go and connect this USB stick to a completely new computer you will still have your

files.

You'll be able to boot tails again and use it normally and that way you'll have an operating system

installed on a really small storage device that you can put on any computer in the world regardless

of what operating system it runs.

And you'll be able to store files and once you turn off that operating system wants to turn off that

computer.

There will be no traces on the computer.

So even if it gets inspected there will be no traces of it even running tails so you probably guessed

by now installing tails on a USB stick is the best option.

And in the next lecture I'm gonna show you how to do that.
