today's video will show you how to install virtualization software that will allow you to install guest operating systems and also how to install Ubuntu Linux to get started let's go to virtualbox org and click on downloads this is the virtualization software that we're going to be using and then you select your platform in this case i'm using windows as my host operating system and so i would click this link here you can also install VirtualBox on lenox on Mac or even solaris I've already downloaded this so I'm going to just pull it up right now and then double-click to run it and I'm just going to accept the defaults click Next Next again that looks fine I'm going to click install and do the same for all the messages like this in the future click finish to complete the installation and then we'll will restart later so the next piece of software we need to install Ubuntu is a bun to itself so we'll go to a bun find the download link and then here we have a couple of different options the primary options are a bun to desktop and a bun to server the primary difference between desktop and server is that the desktop Edition provides a graphical user environment whereas the server does not a bun to server is best for things like web servers or database servers or file servers it's going to be an installation of the operating system where you don't sit down in front of it and use graphical programs Ubuntu desktop on the other hand is for just that flower a bun to and take the default 64 bit I've already done this to save us some time so I'll just close the web browser here and you can see that I've downloaded a bun to you will go ahead and start virtual box and then create a new container or virtual machine for our a bun to operating system installation you can see here that I asked for three bits of information the name the type and the version so I'm going to name it ubuntu desktop then as i type that in there it automatically selected linux as the type and a bunt to as the version if it didn't you can simply use the drop-down boxes and select whatever is appropriate the minimum amount of ram recommended is 512 megabytes I have plenty to use here so I'm going to dedicate about half my resources to this virtual machine so I'll use 4096 megabytes or four gigabytes next we need to create a virtual hard drive click on create and the default of VDI is fine especially if you're not going to be using this up disk image with other virtualization software you have two choices here one is dynamically allocated and the other is fixed to size if your primary concern is about preserving disk space or using his little disk space as possible choose dynamically allocated however if you're looking for performance use fixed size so fine name I will specify 100 gigabytes from my hard drive although 8 gigabytes is sufficient to install the bun 22 I like having some additional space so now we have our virtual machine next you need to install a bun to let's power on the virtual machine to install a bun to click start or you can even right click and click start there either one is fine and now it will ask us for the up on to image that we downloaded I'll select where I downloaded it on my computer and click start you have two options here a bun to and the second one is install a bun to try a bun to simply runs the operating system and memory and lets you try it out however install a bun to actually writes to your hard disk in this case it's going to write to the virtual hard disk in the virtual machine so we're not going to lose any data for example override our current operating system so that's what we're going to do here install I'm going to click continue and accept the defaults here but you can install third-party software that allows you to play mp3s for example and you can also download any patches or bug fixes are other updates for the ubuntu operating system by clicking download updates while installing on click continue and I'm going to just erase this disk again it's a virtual disk that we just created then you can click on the for your time zone I'm just going to leave it at Chicago and you can choose your keyboard here and just fill out your account information and click continue the installation will take to complete so I'm just going to fast forward from this point on once the installation completes your job is done if you're running on physical hardware such as a desktop a laptop or a server however since we're using a virtual machine we need to form one additional step and that additional step is to install some software that helps Linux understand the virtual hardware that it's working with and that piece of software is called guest additions in VirtualBox now that the elation is finished I'm going to power on the Virtual Machine going high light it and click start or right click and click start i'm going to log in with a password that i used during installation and next since this is a virtual machine we need to insert guest additions CD image and install the guest additions then we'll click run and it will ask for our password again so we'll type that in and click authenticate and we'll let the VirtualBox guest additions install okay that's complete we'll just hit return our press enter and then now I'm going to restart this virtual machine so it can use the guest additions and I'll click restart going to log in again with my account and then it's so much better the graphics are filling my display and a bun to is installed [Music]
