OK so now that we understand what tails is and how it works in this lecture I want to show you how to
install tails on a USB stick so that we can start tails on any computer that runs any operating system
using this USB stick.
Now the instructions that I'm going to show you will work on Windows Linux and OS X using the exact
same programs and using the exact same steps that I'm going to show you.
So I'm going to be doing these steps from a Windows computer but these steps will work exactly the same
from Linux and eyes X if you follow them and you faced any problems please ask us in the Q and A section
and we'll respond to you within 15 hours.
So in order to install tells on a USB stick obviously the first requirement is you'll need a USB stick.
Now this USB stick needs to have a minimum size of eight gigabytes.
The next thing that we'll need is details.
Image I'm going to include its download link in the resources of this lecture.
And finally you'll need software to flash details USP image to the USB stick in order to have a beautiful
USB stick with tails on it.
And once we have that we'll be able to connect that to any computer that runs any operating system and
run tales from that computer.
Now the software that we're going to use to flush tales to the USB stick is called Archer.
And again I'm going to include it's download link in the resources of this lecture and this application
works on Linux OS X and windows.
So all you'll have to do is initially just go to the download page right here and it will actually automatically
detect what operating system you're running.
So as you can see right now it's automatically telling me I'm running windows and if I click here it
will download the Windows version for me.
If it's not detecting the right version for you you can click on this little arrow right here and just
download the version that is compatible with your operating system.
Now I already have that downloaded in here as you can see.
So the next thing that I need is the tail's image.
And again as you can see in here I have it and I'm going to include it's download link.
I know right here it says installed from windows but like I said the steps that I'm going to show you
will work on all operating system.
So ignore this click on the download in here.
Once you do it I'll download it for you.
And as you can see I have it right here and my downloads as well.
It should be a file with a dot AMG extension as you can see here.
Once you have these two ready.
The last thing that you'll need is the USB stick that you'll flash details image to.
And I already have my usb stick connected to my windows computer as you can see I have it in here.
It has 28 gigabytes free.
But like I said you only need a minimum of 8 gigabytes.
So what we want to do right now is we're going to use this application error to flush this tells image
to this USB stick.
So the first thing that we'll need to do is to install this application.
So I'm going to double click it and we're going to agree and it's a very very simple installer as you
can see it's finished installing and it's automatically started the application for me.
Now the installation of this on Windows and OS X is literally as simple as this.
All you'll have to do is downloaded double click it and you'll get this window right here.
Now just before I use this just to show you if the installer did interrupt the program for you automatically
you should have the icon of it right here on the desktop.
All you have to do is double click it and it'll start the application for you.
Now using the application is very simple as you can see all you have to do is first of all select the
image that you want to flash to your USP.
And like I said the image for me is this one right here the one in the downloads.
So I'm going to click on select image and I'm already in my downloads directory as you can see in here.
So I'm just going to click on this image and click on open we can see it's selected in here.
The next thing that you'd want to do is select the new SB device that you want to flash the image to.
As you can see it's automatically selected my drive e my device which is the device that I have right
here like I said this is the correct one in your case.
If this wasn't the correct one all you'd have to do is just click on change and select the one that
you want to flash tales to so in my case this is all perfect and all I need to do right now is just
click on flash to flash the image to the USB stick.
But before I do that I want to verify the integrity of the image that I downloaded.
So I want to make sure that this image did not get modified as I downloaded it and I actually explained
how this could happen how it could get modified as it gets downloaded in the previous section.
So if you don't remember that go back and revise that section.
But for now I'm just going to show you how to verify that this image did not get modified so I'm gonna
go back to Firefox again.
We're still at the download page of tales.
I'm just going to click on i already have it downloaded because I do have it downloaded and in order
to verify the integrity of the image that we downloaded we're going to use an extension provided to
us by the tells developers and installed that all we have to do is just click in here and stole tells
verification extension.
I'm going to say yes I want to allow that and I want to add it to my browser.
We're going to say okay and to use this all we'll have to do is just click on verify tales in here.
It's going to ask us to select the image that we downloaded.
Again you want to make sure you go to your downloads and select the image that you downloaded.
We're going to click on open and it's going to check the integrity of the image for us right now and
perfect as you can see is telling us that the verification is successful.
So the image is valid.
It did not get modified as we downloaded it and now we should feel safe flash in it to our USP device
so we can use it to boot into tails and use tails safely in the future so as we see in before I've already
selected the image I've already selected my USB device that I want to flash tails to I'm going to click
on flash to start the flushing process.
I'm going to say yes that's no problem.
I give permissions.
And right now you just want to give it it's time to flush the image verify it and once done it's going
to show was a notification saying the process is finished now.
Like I said all these steps that I've done so far are identical on all operating systems on Windows
Linux and OS X follow them exactly like I showed you right here.
Ignore the fact that it says windows in this page and everything will work exactly as I'm showing you
and perfect as you can see is stillness flashes complete once successful device.
So everything is done with no errors.
And right now Thales is installed on my USP device that is connected to my windows machine.
So right now I can unplug it from this machine and connected to any computer regardless of what operating
system it runs on.
And I'll be able to use tales from that computer without leaving any traces on it.
And I'll show you how to do that in the next lecture.
