WEBVTT 00:00.920 --> 00:09.260 Now that we flashed the cubes image to a USB stick, we can connect this USB stick to a computer and 00:09.260 --> 00:13.190 install cubes as a main operating system on that computer. 00:13.220 --> 00:21.800 Or we can use another USB stick, flash cubes to it, and then use cubes as a live operating system 00:21.800 --> 00:24.140 using this second USB stick. 00:24.140 --> 00:29.960 So we'll be able to connect it to any computer we want, regardless of what operating system it runs. 00:29.960 --> 00:32.210 And then we'll be able to use cubes. 00:32.210 --> 00:38.870 And when we're done, the computer that we used will be back to using its default operating system. 00:39.580 --> 00:44.470 Now, as I mentioned earlier, Cubes is a complex operating system. 00:44.470 --> 00:51.520 So unlike the Thales USB, which we connect to pretty much any computer and boot into tales in order 00:51.520 --> 00:57.850 to boot cubes image, we have to modify the BIOS settings of the computer that we're going to use. 00:58.420 --> 01:04.450 Entering the BIOS settings varies depending on the computer that you have and depending on the motherboard. 01:04.750 --> 01:11.020 On the right here I have a table of the most common computers along with the buttons that you need to 01:11.020 --> 01:14.230 press in order to enter the BIOS settings. 01:14.230 --> 01:21.100 So as soon as you turn on the computer or restart it, you'll need to press the button relevant to your 01:21.100 --> 01:21.670 computer. 01:21.670 --> 01:27.580 And here in order to enter the BIOS settings, once you're there, you want to make sure you enable 01:27.580 --> 01:28.840 virtualization. 01:29.050 --> 01:34.540 In most cases, you'll also need to disable secure boot and set the boot to legacy. 01:34.540 --> 01:39.370 This is optional, but to my experience, I had to do that in a number of laptops. 01:39.940 --> 01:47.530 Then you can finally configure your boot order to boot from USB first, or you can just restart and 01:47.530 --> 01:52.810 enter the boot menu like I showed you before with tails and choose to boot from USB. 01:53.350 --> 01:56.860 So let me show you how to do this on a real computer. 01:58.240 --> 01:58.660 Okay. 01:58.660 --> 02:01.030 So this is a Lenovo computer. 02:01.030 --> 02:07.660 Therefore, based on the table that I just showed you, I will need to press F two as soon as I turn 02:07.660 --> 02:11.770 on this computer in order to enter into its BIOS settings. 02:12.400 --> 02:15.670 So first, I'm going to hit the power button to turn it on. 02:15.670 --> 02:20.440 And as it's being turned on, I'm going to keep pressing f two to enter the settings. 02:22.120 --> 02:22.810 And perfect. 02:22.810 --> 02:25.900 As you can see, I am in the bio settings right now. 02:26.110 --> 02:31.990 Now, keep in mind, depending on your computer, the settings might look different than what I have 02:31.990 --> 02:32.650 in here. 02:33.190 --> 02:38.680 The main thing that you want to keep in mind is to modify the four settings that I mentioned earlier 02:38.680 --> 02:46.480 enabled virtualization, disable secure boot, enable legacy mode and set it to boot from USB first. 02:46.870 --> 02:51.910 Like I said, you might find these settings under different categories or under different windows, 02:51.910 --> 02:55.150 but just make sure you modify the settings. 02:55.420 --> 03:00.470 So as you can see for me, the first window that I see is just an information window. 03:00.490 --> 03:03.130 It doesn't really allow me to modify anything. 03:03.550 --> 03:07.920 Now you can use the keyboard to navigate between these windows or these tabs. 03:07.930 --> 03:12.550 So I'm going to press the right arrow to go to the configuration window. 03:12.970 --> 03:18.820 And in here, the only thing that I want to modify is intel virtualization technology. 03:19.300 --> 03:26.020 So I'm going to use the down arrow to navigate to that, and I'm going to hit enter to change the setting, 03:26.020 --> 03:30.250 press down, to set it to enabled and hit enter again to select it. 03:30.580 --> 03:35.260 Now, if you're not sure about how to use this interface because like I said, you might actually get 03:35.260 --> 03:36.670 a different interface. 03:36.880 --> 03:42.520 Keep an eye on the instructions that you see at the bottom as they tell you exactly how to navigate 03:42.520 --> 03:44.050 and modify the settings. 03:44.650 --> 03:46.950 Now I'm done with the configuration window. 03:46.960 --> 03:51.250 I'm going to press the right arrow again to go into the security tab. 03:51.820 --> 03:56.640 And here again, we have another option that we want to change, which is secure boot. 03:56.650 --> 04:03.370 And like I said, this is optional, but in my experience, this can interfere with booting into cubes 04:03.370 --> 04:05.830 and prevent you from installing cubes. 04:05.860 --> 04:11.800 Therefore, I'm going to scroll down to secure boot again, hit enter to change the settings, change 04:11.800 --> 04:14.380 it to disabled and hit enter again. 04:15.630 --> 04:16.950 We're done with this window now. 04:17.160 --> 04:18.570 These are two settings done. 04:18.570 --> 04:19.740 We have two to go. 04:19.740 --> 04:23.040 So we're going to press right to go to the boot window. 04:24.030 --> 04:27.630 And in here, as you can see, the first option is the boot mode. 04:27.630 --> 04:30.720 We want to change that from UEFI to legacy. 04:30.720 --> 04:33.660 So again, I'm going to hit enter and select legacy. 04:34.430 --> 04:38.240 You might not get this, but as you can see now, I got an extra option here. 04:38.240 --> 04:44.330 The second one, the bullet priority, it said to you, if I first again, I'm going to hit enter and 04:44.330 --> 04:46.190 change that to legacy first. 04:46.730 --> 04:49.070 And finally, you don't even have to do this. 04:49.070 --> 04:53.480 I'm going to change the boot order so that it boots from USB first. 04:53.510 --> 04:58.790 You don't have to do this because you can exit this and just manually choose to boot from USB. 04:59.060 --> 05:04.280 I'm just going to do it here so that when I restart I won't even have to enter the boot menu. 05:04.670 --> 05:10.700 So I'm just going to scroll down to the USB and I bring it all the way up again. 05:10.700 --> 05:16.190 I'm looking at the bottom of the BIOS screen to see how I can move items up and down. 05:16.190 --> 05:21.890 So based on that screen is telling me that I can use F five and F six to do so. 05:26.560 --> 05:27.060 Okay. 05:27.070 --> 05:28.690 Now we're done with all the settings. 05:28.690 --> 05:36.160 So we enabled virtualization, we disabled secure boot, we disabled EFI and we set the boot to legacy 05:36.160 --> 05:39.210 and we set it to boot from USB first. 05:39.220 --> 05:40.600 We're done with everything. 05:40.600 --> 05:42.010 We're going to go to the exit. 05:42.010 --> 05:48.760 So again, I'm going to press the right arrow again and I'm going to select the first option exit saving 05:48.760 --> 05:49.510 settings. 05:50.170 --> 05:52.300 It's going to ask me, do I really want to do this? 05:52.300 --> 05:53.680 I'm going to say yes. 05:54.160 --> 05:58.990 And before hitting enter because once I hit Enter, it's going to restart my computer. 05:58.990 --> 06:05.230 I'm going to connect the USB device that I flashed the Cube's ISO image to. 06:06.260 --> 06:09.780 I'm also going to connect a second USB device. 06:09.800 --> 06:15.230 This is the one that I showed you in green and this is the one that I'm going to install cubes to. 06:15.230 --> 06:19.390 So I'm not going to install it as a main operating system on this computer. 06:19.400 --> 06:26.540 I will install it just to this USB stick so that I can use this second USB stick to run cubes on any 06:26.540 --> 06:28.820 computer that can support cubes. 06:28.820 --> 06:34.280 So I'm going to use it as a live operating system similar to the way that we were using tails. 06:35.060 --> 06:40.700 And now that we are ready to restart, I'm going to hit enter to save the changes and restart the computer. 06:42.310 --> 06:49.660 Now as you can see it automatically booted using the USB stick into the cubes image that we flash to 06:49.660 --> 06:50.980 our USB stick. 06:51.160 --> 06:57.210 If this didn't work for you, if it didn't boot automatically into this, then enter your boot settings 06:57.220 --> 07:04.150 as the system is starting similar to what we did with tails and force it to boot from the USB stick 07:04.150 --> 07:06.520 that we flashed cubes to. 07:07.820 --> 07:14.810 So now we're ready to go ahead and install cubes and I'll show you how to do that in details in the 07:14.810 --> 07:15.680 next lecture.
