Now that we flashed the cubes image to a USB stick we can't connect this USB stick to a computer and
install cubes as the main operating system on that computer.
Or we can use another USB stick flash cubes to it and then use cubes as alive operating system using
this second USB stick.
So we'll be able to connect it to any computer we want regardless of what operating system it runs.
And then we'll be able to use cubes and when we're done the computer that we used will be back to using
its default operating system now.
As I mentioned earlier cubes is a complex operating system.
So unlikely tells us B which we connect to pretty much any computer and put into tales in order to wood
cubes image.
We have to modify the BIOS settings of the computer that we're going to use entering the BIOS settings
varies depending on the computer that you have and depending on the motherboard.
On the right here I have a table of the most common computers along with the buttons that you need to
press in order to enter the BIOS settings.
So as soon as you turn on the computer or restarted you'll need to press the button relevant to your
computer in here in order to enter the BIOS settings.
Once you're there you want to make sure you enable virtualization.
In most cases you'll also need to disable secure booth and set the booth to legacy.
This is optional but to my experience I had to do that in a number of laptops.
Then you can finally configure your booth order to Booth from USP first or you can just restart and
enter the booth menu like I showed you before with tails and choose to Booth from USP.
So let me show you how to do this on aerial computer OK.
So this is a Lenovo computer therefore based on the table that I just showed you I will need to press
F to as soon as I turn on this computer in order to enter into its bio settings.
So first I'm going to hit the power button to turn it on and as it's being turned on I'm going to keep
pressing F2 to enter the settings and perfect as you can see I am in the BIOS settings right now.
Now keep in mind depending on your computer the settings might look different than what I have in here.
The main thing that you want to keep in mind is to modify the four settings that I mentioned earlier
enabled virtualization disables secure would enable legacy mode and said it's too good from USP first.
Like I said you might find these settings under different categories or under different windows but
just make sure you modify the settings.
So as you can see for me the first window that I see is just an information window.
It doesn't really allow me to modify anything.
Now you can use the keyboard to navigate between these windows or these tabs.
So I'm going to press the right arrow to go to the configuration window and in here the only thing that
I want to modify is Intel virtualization technology.
So I'm going to use the down arrow to navigate to that and I'm going to hit enter to change the setting
press down to set it to enabled and hit enter again to select it.
Now if you're not sure about how to use this interface because like I said you might actually get a
different interface.
Keep an eye on the instructions that you see at the bottom as they tell you exactly how to navigate
and modify the settings.
Now I'm done with the configuration window.
I'm going to press the right arrow again to go into the security tab and here again we have another
option that we want to change which is secure.
Good.
And like I said this is optional but in my experience this can't interfere with booting into cubes and
prevents you from installing cubes.
Therefore I'm going to scroll down to secure a booth again.
Hit enter to change the settings change it to disabled and hit enter again.
We're done with this window no.
These are two settings done we have two to go.
So we're going to press right to go to the good window and in here as you can see the first option is
the booth mode.
We want to change that from you I to legacy.
So again I'm going to hit enter and select legacy you might not get this but as you can see now I got
an extra option here.
The second one the with priority it said to you.
Efi first again I'm going to hit enter and change that legacy first.
And finally you don't even have to do this.
I'm going to change the boot order so that it routes from you SB first.
You don't have to do this because you can exit this and just manually choose to boot from USP.
I'm just going to do it here so that when I restart I won't even have to enter the boot menu so I'm
just gonna scroll down to the USP and I'll bring it all the way up again.
I'm looking at the bottom of the bios screen to see how I can move items up and down.
So based on that screen is telling me that I can use a five and six to do so
OK.
Now we're done with all the settings so enabled virtualization with disabled secure boot.
We disabled you EFI and we said the boot to legacy and we set it to boot from U.S. B first.
We're done with everything.
We're going to go to the exit so again I'm going to press the right arrow again and I'm going to select
the first option exit saving settings that's going to ask me Do I really want to do this.
I'm going to say yes.
And before hit and enter because once I hit enter it's going to restart my computer.
I'm going to connect the new SB device that I flashed the cubes iso image to I'm also going to connect
a second USB device.
This is the one that I showed you in green and this is the one that I'm going to install cubes to.
So I'm not going to install it as a main operating system on this computer.
I will install it just to this USB stick so that I can use the second USB stick to run cubes on any
computer that can support cubes.
So I'm going to use it as a live operating system similar to the way that we were using Intel's and
now that we are ready to restart.
I'm going to hit enter to save the changes and restart the computer now.
As you can see it automatically booted using the USB stick into the cubes image that we flashed to our
USB stick.
If this didn't work for you if it did it would automatically into this then enter your boot settings
as the system is starting similar to what we did with tails and force it to boot from the USB stick
that we flashed cubes to.
So now we're ready to go ahead and install cubes and I'll show you how to do that.
In details in the next lecture.
