Continue from the previous part: Install Ubuntu on VirtualBox (Part 1). We have already downloaded all the needed softwares and finish the virtualbox installation, so far so good~ Now launch the newly installed virtualbox, let’s … [Create a virtual machine] Remember we mentioned that the OS needs to be installed on a physical machine in our last post? Yeah, right now we are gonna to prepare a virtual physical machine, using virtualbox. The fresh installed virtualbox looks like below: Click “File->Preferences…”, tweak some global settings before we start, you can modify anything you want to make you comfortable, here I recommend to change the “Default Hard Disk Folder” and “Default Machine Folder”: After preferences setting, click the “New” button on toolbar to start the “create new virtual machine wizard”: Click “Next”, in the next screen, input the virtual machine name and its OS type, since we are now installing ubuntu 9.04 desktop edition, we can put something looks like below: “Next”, now the wizard asks us to input the RAM of the virtual machine, it’s now starting to look like a real machine, isn’t it? Here I assign this VM (virtual machine) 512M RAM, you can change it to meet your needs, just note that the RAM you gave to the VM will later be occupied from your real machine (the one you install windows on), so don’t assign too much memory if you don’t have so much: “Next” comes to the hard disk, yes, it’s still a virtual one. Since we haven’t created any virtual hard disk right now, we need to select “Create new hard disk”, also check the “Boot Hard Disk (Primary Master)” option, we will later boot our ubuntu on this hard disk: “Next”, cause we select “Create new hard disk” in the former screen, now we are heading to the “create new virtual disk wizard”: “Next”… (why so much next:-)), we are asked to choose the virtual hard disk type, in consideration of the flexibility, we choose “Dynamic expanding storage” here, maybe a little bit slower than “Fixed-size storage”, but that’s worth it: “Next” comes the virtual disk location and size… (why so much next? Maybe you will start to complain:), but trust me, it’s close, not so much next remains:)) since we are already finished the global “Default Hard Disk Folder” setting before, we can just leave the “Virtual Disk” setting here to its own, it will follow our global setting if we don’t explicitly set it. Since we have selected “Dynamic expanding storage” type before, the disk size here is just a maximum size of your disk, not the exact size, so feel free to set it to any size you want. The actual limit is your real physical hard disk size if you set it to a very large number, like 2T: “Next” again, we finally see a “finish”, but don’t count your chickens now, it’s only the finish of the virtual hard disk creation:) After click “finish”, we finally got the last “finish”, check the parameters again and click “finish” to create our first virtual machine: After successfully creation, finally a virtual machine shows up: We will later create ubuntu on this virtual machine in this articles’s 3rd part.
