1 00:00:00,000 --> 00:00:06,000 So now that we understand what Thales is and how it works in this lecture, I want to show you how to 2 00:00:06,000 --> 00:00:14,000 install Thales on a USB stick so that we can start Thales on any computer that runs any operating system 3 00:00:14,000 --> 00:00:16,000 using this USB stick. 4 00:00:17,000 --> 00:00:21,000 Keep in mind the USB stick that you're going to pick in here will be formatted. 5 00:00:21,000 --> 00:00:24,000 Everything stored on it will be deleted. 6 00:00:24,000 --> 00:00:31,000 Now, the instructions that I'm going to show you will work on Windows Linux and OS X using the exact 7 00:00:31,000 --> 00:00:36,000 same programs and using the exact same steps that I'm going to show you. 8 00:00:36,000 --> 00:00:43,000 So I'm going to be doing these steps from a Windows computer, but these steps will work exactly the 9 00:00:43,000 --> 00:00:45,000 same from Linux and OS X. 10 00:00:46,000 --> 00:00:52,000 If you follow them and you face any problems, please ask us in the Q&A section and we'll respond to 11 00:00:52,000 --> 00:00:54,000 you within 15 hours. 12 00:00:54,000 --> 00:01:02,000 So in order to install Thales on a USB stick, obviously the first requirement is you'll need a USB 13 00:01:02,000 --> 00:01:03,000 stick. 14 00:01:03,000 --> 00:01:08,000 Now this USB stick needs to have a minimum size of eight gigabytes. 15 00:01:09,000 --> 00:01:13,000 The next thing that we'll need is the Thales image. 16 00:01:13,000 --> 00:01:17,000 I'm going to include its download link in the resources of this lecture. 17 00:01:17,000 --> 00:01:26,000 And finally, you'll need software to flash the Thales USB image to the USB stick in order to have a 18 00:01:26,000 --> 00:01:29,000 bootable USB stick with Thales on it. 19 00:01:29,000 --> 00:01:35,000 And once we have that, we'll be able to connect that to any computer that runs any operating system 20 00:01:35,000 --> 00:01:39,000 and run Thales from that computer. 21 00:01:39,000 --> 00:01:45,000 Now the software that we're going to use to flash Thales to the USB stick is called Etcher. 22 00:01:45,000 --> 00:01:50,000 And again I'm going to include its download link in the resources of this lecture. 23 00:01:50,000 --> 00:01:54,000 And this application works on Linux, OS X and Windows. 24 00:01:54,000 --> 00:02:02,000 So all you'll have to do is literally just go to the download page right here and it'll actually automatically 25 00:02:02,000 --> 00:02:04,000 detect what operating system you're running. 26 00:02:04,000 --> 00:02:10,000 So as you can see right now, it's automatically telling me I'm running windows and if I click here, 27 00:02:10,000 --> 00:02:12,000 it will download the Windows version for me. 28 00:02:13,000 --> 00:02:18,000 If it's not detecting the right version for you, you can click on this little arrow right here and 29 00:02:18,000 --> 00:02:24,000 just download the version that is compatible with your operating system. 30 00:02:25,000 --> 00:02:25,000 Now. 31 00:02:25,000 --> 00:02:28,000 I already have that downloaded in here, as you can see. 32 00:02:28,000 --> 00:02:33,000 So the next thing that I need is the tails image. 33 00:02:33,000 --> 00:02:38,000 And again, as you can see in here, I have it and I'm going to include its download link. 34 00:02:38,000 --> 00:02:41,000 I know right here it says install from Windows. 35 00:02:41,000 --> 00:02:46,000 But like I said, this steps that I'm going to show you will work on all operating system. 36 00:02:46,000 --> 00:02:48,000 So ignore this. 37 00:02:48,000 --> 00:02:50,000 Click on the download in here. 38 00:02:50,000 --> 00:02:52,000 Once you do it will download it for you. 39 00:02:52,000 --> 00:02:56,000 And as you can see, I have it right here in my downloads as well. 40 00:02:56,000 --> 00:03:01,000 It should be a file with a dot img extension as you can see here. 41 00:03:02,000 --> 00:03:09,000 Once you have these two ready, the last thing that you'll need is the USB stick that you'll flash the 42 00:03:09,000 --> 00:03:10,000 tails image to. 43 00:03:11,000 --> 00:03:16,000 And I already have my USB stick connected to my Windows computer. 44 00:03:16,000 --> 00:03:18,000 As you can see, I have it in here. 45 00:03:18,000 --> 00:03:21,000 It has 28GB free. 46 00:03:21,000 --> 00:03:25,000 But like I said, you only need a minimum of eight gigabytes. 47 00:03:25,000 --> 00:03:33,000 So what we want to do right now is we're going to use this application etcher to flash this tails image 48 00:03:33,000 --> 00:03:35,000 to this USB stick. 49 00:03:36,000 --> 00:03:40,000 So the first thing that we'll need to do is to install this application. 50 00:03:40,000 --> 00:03:42,000 So I'm going to double click it. 51 00:03:44,000 --> 00:03:46,000 And we're going to agree. 52 00:03:46,000 --> 00:03:54,000 And it's a very, very simple installer, as you can see it finished installing and it automatically 53 00:03:54,000 --> 00:03:56,000 started the application for me. 54 00:03:56,000 --> 00:04:01,000 Now the installation of this on Windows and OS X is literally as simple as this. 55 00:04:02,000 --> 00:04:06,000 All you'll have to do is download it, double click it, and you'll get this window right here. 56 00:04:07,000 --> 00:04:14,000 Now, just before I use this, just to show you, if the installer didn't run the program for you automatically, 57 00:04:14,000 --> 00:04:18,000 you should have the icon of it right here on the desktop. 58 00:04:18,000 --> 00:04:23,000 All you'll have to do is double click it and it'll start the application for you. 59 00:04:24,000 --> 00:04:27,000 Now, using the application is very simple, as you can see. 60 00:04:27,000 --> 00:04:33,000 All you'll have to do is, first of all, select the image that you want to flash to your USB. 61 00:04:33,000 --> 00:04:38,000 And like I said, the image for me is this one right here, the one in the downloads. 62 00:04:38,000 --> 00:04:45,000 So I'm going to click on Select Image and I'm already in my downloads directory, as you can see in 63 00:04:45,000 --> 00:04:46,000 here. 64 00:04:46,000 --> 00:04:50,000 So I'm just going to click on this image and click on Open. 65 00:04:51,000 --> 00:04:53,000 We can see it's selected in here. 66 00:04:53,000 --> 00:05:01,000 The next thing that you'd want to do is select the USB device that you want to flash the image to. 67 00:05:01,000 --> 00:05:08,000 As you can see, it automatically selected my drive, my device, which is the device that I have right 68 00:05:08,000 --> 00:05:08,000 here. 69 00:05:08,000 --> 00:05:10,000 Like I said, this is the correct one. 70 00:05:10,000 --> 00:05:16,000 In your case, if this wasn't the correct one, all you'll have to do is just click on change and select 71 00:05:16,000 --> 00:05:20,000 the one that you want to flash tales to keep in mind. 72 00:05:20,000 --> 00:05:23,000 The USB stick that you're going to pick in here will be formatted. 73 00:05:23,000 --> 00:05:26,000 Everything stored on it will be deleted. 74 00:05:26,000 --> 00:05:32,000 So if you're sure this is the correct one, you can click on Flash to start the process. 75 00:05:32,000 --> 00:05:39,000 But before I do that, I want to verify the integrity of the image that I downloaded. 76 00:05:39,000 --> 00:05:44,000 So I want to make sure that this image did not get modified as I downloaded it. 77 00:05:44,000 --> 00:05:51,000 And I actually explained how this could happen, how it could get modified as it gets downloaded and 78 00:05:51,000 --> 00:05:52,000 in the previous section. 79 00:05:52,000 --> 00:05:56,000 So if you don't remember that, go back and revise that section. 80 00:05:56,000 --> 00:06:02,000 But for now, I'm just going to show you how to verify that this image did not get modified. 81 00:06:03,000 --> 00:06:05,000 So I'm going to go back to Firefox again. 82 00:06:05,000 --> 00:06:08,000 We're still at the download page of Tales. 83 00:06:09,000 --> 00:06:10,000 I'm just going to click on. 84 00:06:10,000 --> 00:06:13,000 I already have it downloaded because I do have it downloaded. 85 00:06:13,000 --> 00:06:20,000 And in order to verify the integrity of the image that we downloaded, we're going to use an extension 86 00:06:20,000 --> 00:06:26,000 provided to us by the Tales developers and to install that, all we have to do is just click in here, 87 00:06:26,000 --> 00:06:29,000 install tales, verification extension. 88 00:06:30,000 --> 00:06:35,000 I'm going to say, yes, I want to allow that and I want to add it to my browser. 89 00:06:35,000 --> 00:06:42,000 We're going to say, okay, and to use this, all we'll have to do is just click on Verify Tales in 90 00:06:42,000 --> 00:06:43,000 here. 91 00:06:43,000 --> 00:06:47,000 It's going to ask us to select the image that we downloaded. 92 00:06:47,000 --> 00:06:52,000 Again, you want to make sure you go to your downloads and select the image that you downloaded. 93 00:06:52,000 --> 00:06:59,000 We're going to click on Open and it's going to check the integrity of the image for us right now. 94 00:07:00,000 --> 00:07:01,000 And perfect. 95 00:07:01,000 --> 00:07:07,000 As you can see, it's telling us that the verification is successful, so the image is valid. 96 00:07:07,000 --> 00:07:16,000 It did not get modified as we downloaded it and now we should feel safe flashing it to our USB device 97 00:07:16,000 --> 00:07:22,000 so we can use it to boot into tales and use tales safely in the future. 98 00:07:23,000 --> 00:07:26,000 So as we've seen before, I've already selected the image. 99 00:07:26,000 --> 00:07:31,000 I've already selected my USB device that I want to flash tales to. 100 00:07:31,000 --> 00:07:35,000 I'm going to click on Flash to start the flashing process. 101 00:07:35,000 --> 00:07:38,000 I'm going to say, yes, that's no problem. 102 00:07:38,000 --> 00:07:42,000 I give permissions and right now you just want to give it. 103 00:07:42,000 --> 00:07:49,000 It's time to flash the image, verify it, and once done, it's going to show us a notification saying 104 00:07:49,000 --> 00:07:50,000 the process is finished. 105 00:07:51,000 --> 00:07:58,000 Now, like I said, all these steps that I've done so far are identical on all operating systems on 106 00:07:58,000 --> 00:08:00,000 Windows, Linux and OSX. 107 00:08:00,000 --> 00:08:04,000 Follow them exactly like I showed you right here. 108 00:08:04,000 --> 00:08:10,000 Ignore the fact that it says Windows in this page and everything will work exactly as I'm showing you. 109 00:08:12,000 --> 00:08:13,000 And perfect. 110 00:08:13,000 --> 00:08:17,000 As you can see, its stillness flash is complete one successful device. 111 00:08:17,000 --> 00:08:20,000 So everything is done with no errors. 112 00:08:20,000 --> 00:08:28,000 And right now tills is installed on my USB device that is connected to my windows machine. 113 00:08:28,000 --> 00:08:35,000 So right now I can unplug it from this machine and connect it to any computer, regardless of what operating 114 00:08:35,000 --> 00:08:37,000 system it runs on. 115 00:08:37,000 --> 00:08:44,000 And I'll be able to use tales from that computer without leaving any traces on it. 116 00:08:44,000 --> 00:08:48,000 And I'll show you how to do that in the next lecture.
