WEBVTT 00:01.050 --> 00:01.850 Okay. 00:01.860 --> 00:08.100 So now that we understand what tills is and how it works in this lecture, I want to show you how to 00:08.100 --> 00:16.350 install Thales on a USB stick so that we can start Thales on any computer that runs any operating system 00:16.350 --> 00:18.840 using this USB stick. 00:19.260 --> 00:26.160 Now, the instructions that I'm going to show you will work on Windows, Linux and OS X using the exact 00:26.160 --> 00:30.650 same programs and using the exact same steps that I'm going to show you. 00:30.660 --> 00:37.770 So I'm going to be doing these steps from a Windows computer, but these steps will work exactly the 00:37.770 --> 00:40.650 same from Linux and OS X. 00:40.650 --> 00:46.860 If you follow them and you face any problems, please ask us in the Q&A section and we'll respond to 00:46.860 --> 00:48.630 you within 15 hours. 00:49.410 --> 00:57.120 So in order to install Thales on a USB stick, obviously the first requirement is you'll need a USB 00:57.120 --> 00:57.840 stick. 00:58.110 --> 01:03.270 Now this USB stick needs to have a minimum size of eight gigabytes. 01:03.900 --> 01:06.810 The next thing that we'll need is details. 01:06.810 --> 01:07.500 Image. 01:07.680 --> 01:12.270 I'm going to include its download link in the resources of this lecture. 01:12.660 --> 01:20.880 And finally, you'll need software to flash the Thales USB image to the USB stick in order to have a 01:20.880 --> 01:23.880 bootable USB stick with tails on it. 01:23.880 --> 01:30.480 And once we have that, we'll be able to connect that to any computer that runs any operating system 01:30.480 --> 01:33.450 and run tales from that computer. 01:34.170 --> 01:40.020 Now, the software that we're going to use to flash stills to the USB stick is called Edger. 01:40.140 --> 01:45.090 And again, I'm going to include its download link in the resources of this lecture. 01:45.090 --> 01:49.320 And this application works on Linux, OSX and Windows. 01:49.320 --> 01:56.760 So all you'll have to do is literally just go to the download page right here and it'll actually automatically 01:56.760 --> 01:59.220 detect what operating system you're running. 01:59.220 --> 02:04.740 So as you can see right now, it's automatically telling me I'm running windows and if I click here, 02:04.740 --> 02:07.200 it will download the Windows version for me. 02:07.890 --> 02:13.260 If it's not detecting the right version for you, you can click on this little arrow right here and 02:13.260 --> 02:18.840 just download the error version that is compatible with your operating system. 02:19.870 --> 02:20.290 Now. 02:20.290 --> 02:23.570 I already have that downloaded in here, as you can see. 02:23.590 --> 02:28.230 So the next thing that I need is the tail's image. 02:28.240 --> 02:33.150 And again, as you can see in here, I have it and I'm going to include its download link. 02:33.160 --> 02:35.950 I know right here it says install from Windows. 02:35.950 --> 02:41.310 But like I said, the steps that I'm going to show you will work on all operating system. 02:41.320 --> 02:42.670 So ignore this. 02:42.700 --> 02:44.680 Click on the download in here. 02:44.680 --> 02:47.260 Once you do it, I'll download it for you. 02:47.260 --> 02:50.950 And as you can see, I have it right here in my downloads as well. 02:51.040 --> 02:55.180 It should be a file with a dot img extension. 02:55.180 --> 03:02.410 As you can see here, once you have these two ready, the last thing that you'll need is the USB stick 03:02.410 --> 03:05.560 that you'll flash details image to. 03:06.370 --> 03:11.260 And I already have my USB stick connected to my Windows computer. 03:11.290 --> 03:13.330 As you can see, I have it in here. 03:13.330 --> 03:19.780 It has 28 gigabytes free, but like I said, you only need a minimum of eight gigabytes. 03:20.470 --> 03:28.150 So what we want to do right now is we're going to use this application atcha to flash this tails image 03:28.150 --> 03:30.340 to this USB stick. 03:30.760 --> 03:35.320 So the first thing that we'll need to do is to install this application. 03:35.590 --> 03:37.360 So I'm going to double click it. 03:39.000 --> 03:40.680 And we're going to agree. 03:41.690 --> 03:44.240 And it's a very, very simple installer. 03:45.080 --> 03:50.840 As you can see, it's finished installing and it automatically started the application for me. 03:51.290 --> 03:56.610 Now the installation of this on Windows and OS X is literally as simple as this. 03:56.630 --> 04:01.520 All you'll have to do is download it, double click it, and you'll get this window right here. 04:02.150 --> 04:08.120 Now, just before I use this, just to show you, if the installer didn't run the program for you, 04:08.120 --> 04:13.040 automatically, you should have the icon of it right here on the desktop. 04:13.430 --> 04:18.050 All you'll have to do is double click it and it will start the application for you. 04:18.830 --> 04:21.260 Now using the application is very simple. 04:21.290 --> 04:27.350 As you can see, all you'll have to do is, first of all, select the image that you want to flash to 04:27.350 --> 04:28.460 your USB. 04:28.490 --> 04:33.140 And like I said, the image for me is this one right here, the one in the downloads. 04:33.230 --> 04:40.130 So I'm going to click on Select Image and I'm already in my downloads directory, as you can see in 04:40.130 --> 04:40.740 here. 04:40.760 --> 04:45.110 So I'm just going to click on this image and click on Open. 04:46.110 --> 04:48.470 We can see it's selected in here. 04:48.480 --> 04:56.340 The next thing that you'd want to do is select the USB device that you want to flash the image to. 04:56.490 --> 05:02.520 As you can see, it automatically selected my drive e my device E, which is the device that I have 05:02.520 --> 05:03.020 right here. 05:03.030 --> 05:05.310 Like I said, this is the correct one. 05:05.550 --> 05:11.250 In your case, if this wasn't the correct one, all you'll have to do is just click on change and select 05:11.250 --> 05:13.680 the one that you want to flash tails to. 05:14.490 --> 05:16.740 So in my case, this is all perfect. 05:16.740 --> 05:23.640 And all I need to do right now is just click on Flash to flash the image to the USB stick. 05:24.540 --> 05:30.680 But before I do that, I want to verify the integrity of the image that I downloaded. 05:30.690 --> 05:36.240 So I want to make sure that this image did not get modified as I downloaded it. 05:36.540 --> 05:43.320 And I actually explained how this could happen, how it could get modified as it gets downloaded in 05:43.320 --> 05:44.400 the previous section. 05:44.400 --> 05:47.970 So if you don't remember that, go back and revise that section. 05:48.060 --> 05:54.210 But for now, I'm just going to show you how to verify that this image did not get modified. 05:54.720 --> 05:57.330 So I'm going to go back to Firefox again. 05:57.330 --> 05:59.850 We're still at the download page of Tails. 06:00.480 --> 06:05.040 I'm just going to click on I already have it downloaded because I do have it downloaded. 06:05.160 --> 06:11.850 And in order to verify the integrity of the image that we downloaded, we're going to use an extension 06:11.850 --> 06:14.880 provided to us by the tails developers. 06:14.880 --> 06:21.120 And to install that, all we have to do is just click in here, install tails, verification extension. 06:21.870 --> 06:27.180 I'm going to say yes, I want to allow that and I want to add it to my browser. 06:27.450 --> 06:33.960 We're going to say, okay, and to use this, all we'll have to do is just click on Verify Tails. 06:33.960 --> 06:38.700 And here it's going to ask us to select the image that we downloaded. 06:38.700 --> 06:44.040 Again, you want to make sure you go to your downloads and select the image that you downloaded. 06:44.340 --> 06:51.180 We're going to click on Open and it's going to check the integrity of the image for us right now. 06:52.140 --> 06:52.950 And perfect. 06:52.950 --> 06:59.460 As you can see, it's telling us that the verification is successful so the image is valid. 06:59.460 --> 07:08.070 It did not get modified as we downloaded it, and now we should feel safe flashing it to our USB device 07:08.070 --> 07:13.950 so we can use it to boot into tails and use tails safely in the future. 07:14.940 --> 07:18.450 So as we've seen before, I've already selected the image. 07:18.450 --> 07:23.110 I've already selected my USB device that I want to flash stills to. 07:23.130 --> 07:27.210 I'm going to click on Flash to start the flashing process. 07:27.630 --> 07:29.940 I'm going to say, yes, that's no problem. 07:29.940 --> 07:37.710 I give permissions and right now you just want to give it its time to flash the image, verify it, 07:37.710 --> 07:42.540 and once done, it's going to show us a notification saying the process is finished. 07:43.590 --> 07:50.340 Now, like I said, all these steps that I've done so far are identical on all operating systems on 07:50.340 --> 07:52.350 Windows, Linux and OS X. 07:52.350 --> 07:55.590 Follow them exactly like I showed you right here. 07:55.620 --> 08:02.490 Ignore the fact that it says Windows in this page and everything will work exactly as I'm showing you. 08:03.980 --> 08:04.760 And perfect. 08:04.760 --> 08:09.230 As you can see it, stillness flash is complete one successful device. 08:09.230 --> 08:12.260 So everything is done with no errors. 08:12.260 --> 08:19.940 And right now tills is installed on my USB device that is connected to my windows machine. 08:19.940 --> 08:27.380 So right now I can unplug it from this machine and connect it to any computer regardless of what operating 08:27.380 --> 08:28.970 system it runs on. 08:29.180 --> 08:37.310 And I'll be able to use tales from that computer without leaving any traces on it, and I'll show you 08:37.310 --> 08:39.740 how to do that in the next lecture.
