 Hi everyone, in this video we will see how to install VirtualBox in A1218 and will also install A1218 OS image on the VirtualBox. So let's first open a browser and type in install virtualbox. So I will open this virtualbox.org link. So it shows me different platforms because I am running A1218 so I will select Linux distributions and then A1218. So from here it allows me to save this db file and I will save it in the downloads folder. So the download has completed, let's open a terminal and go to the downloads folder. Now I will use the sudo dpkg-i and then the filename command to install from this db file. So it has started the installation, let's wait for the installation to finish. So now it has installed VirtualBox, let's run it using the virtualbox command. So you can see it opened this Oracle VM VirtualBox Manager. Let's create a new VM using this new button, I will name it A1218 and the type will be Linux version is 164 bit, let's press next. Now I will set the RAM size to be 4 GB and click on next. So here it is asking about the hard disk. So we need a virtual hard disk to run with the virtual machine because I do not have any existing virtual hard disk, I will create a new virtual hard disk, let's click on create. I will keep the hard disk type as virtual box disk image and then there are two types of hard disk, one is dynamically allocated and another is fixed size. So what does it mean by dynamically allocated? It means that the initial virtual hard disk size would be smaller than 10 GB and as and when we store more data into this virtual hard drive, its size will increase. So I will keep it as dynamically allocated and click on next. I will set the size as 10 GB only and click on create. So this has created a new virtual machine with 4 GB as the RAM memory and other properties which we can see here. Now we need to install the O1 to operating system on this virtual machine. So before that let's download the O1 to ISO image so that we can install it in this virtual machine. So I will open the browser and type in download O1 to 20 ISO. So you can download this O1 to ISO using this releases.O1.2.com link. Let's open this. So there are two types of image, one is desktop and another is server. Let's install the desktop image and here it will allow us to save this file because it's a large 3 GB file I have already downloaded it. So I will click on cancel but you can click on OK to save this file. So let's now open the virtual box and because I want to run this virtual machine using that ISO file, I will click on settings. Then I will go to storage and here it is showing that optical drive is empty. I will click on this small icon and then choose a disk file. Here I will choose the image ISO file and click on open and then select OK. So now here we can see that it has this ISO image file in the optical drive and now we can start the VM. So this will boot up the virtual machine using this ISO file. It will take some time so let's wait for it to complete. Alright so once it boots up we can install Ubuntu just like we installed Ubuntu in a normal physical machine. So let's click on install Ubuntu and I will click on continue. Let me try to increase the size a bit. View virtual screen scale to 150%. Alright. Okay. So I will just keep it normal installation and click on continue. So it says that will areas that it can install Ubuntu so we can just select install now and press this continue button. So here we can select the region so I will choose this India and click on continue. Now we can configure the username and password for our Ubuntu operating system. I will just add the name as sort of and here I will write Ubuntu VM. And username I will just keep it as sort of and I will also add a password okay and then I can continue. So this will start the installation and it might take a long time so let's wait for it to finish. So now the installation has completed. Let's click on restart now. So the virtual machine has restarted. I will select my username and enter the password. I will just keep all of these as of now and click on next and next and then done. So this starts our Ubuntu operating system in the virtual machine. The first thing that we will do is reset the resolution. So I will scale it back to 100% and change the display settings to match the resolution of virtual machine to be the same as the host machine which is 1920 times 1200 and apply these changes. So we can go to full screen using control plus F. So I will switch to the full screen mode. So this is the Ubuntu virtual machine and as you can see it is just like running Ubuntu on a physical machine. Let's open the terminal. So we can open the terminal using control plus alt plus t. Let's increase the font size a bit. So we can run various Ubuntu commands and we can use exit to exit the terminal. So that's it for this video. Thanks and have a nice day.
