How to install Ubuntu on Oracle VirtualBox

Oracle VirtualBox is a cross-platform virtualization engine. You can install and any operating system inside your currently running operating system. Whether you are using Windows, MAC OS, or Linux you can always install any other operating system on top of it.

Note: We will be using Windows 7 as the host, and Ubuntu 14.04 x64 as the guest.

Downloads

Go to the official website of Oracle VirtualBox and download the latest suitable version according to you computer, and then install it.

Download the ISO image of Ubuntu from here.

When downloading Ubuntu ISO file, make sure to select 64-bit version.

Create Virtual Machine

Okay, So now let’s begin with creating a virtual machine. A virtual machine is just like a real machine except that it doesn’t physically exists.

 

Click ‘New‘ button to open a dialog.

Enter the name for new virtual machine. Since we are going to install Ubuntu 14.04, let’s name it ubuntu1404. Now VirtualBox will probably choose the correct ‘Type’ and ‘Version’, but in case it doesn’t, you can set ‘Type’ to Linux and ‘Version’ to ‘Ubuntu (64 bit)’ manually.

Then press ‘Next’ to proceed.

The memory size depends on your host machine memory size. This is a very important step. You should allocate at least 1GB to as much as you can to smoothly run the virtual machine. However, make sure you leave enough memory for your host machine, which is very necessary. i.e, if you have total 8GB RAM, you can allocate 4GB to virtual, and leave 4GB for host. If you have got total 4GB, then allocate 1GB or 2GB for virtual.

In this case, my host machine has 12GB of physical RAM, so I would allocate 8192MB for the Ubuntu.

Change the storage type from the default ‘Dynamically allocated’ to ‘Fixed size’ to increase performance.

You can also leave it dynamic, but it will be a little slow. The only advantage this option provides is, the virtual hard drive will only allocate the space that is being used. i.e, If you created hard drive of 15GB, and Ubuntu is using just 8GB then only 8GB of your physical hard drive will be consumed, and will increase when required.

By default VirtualBox selects the minimum space required, which is 8GB. Which is too small for actual usage of Ubuntu. You should increase it and set to at least 15GB.

We have got plenty of space, so I will choose 100GB.

The virtual machine is created now! Now let us install the operating system.

Select the newly created virtual machine and Click ‘Settings’ button. Click on ‘Storage’ category and then ‘Empty’ under Controller:IDE. Click “CD/DVD” icon on right hand side and select the ubuntu ISO file to mount.

Make sure the VT-x/Virtualization Technology has been enabled in your computer’s BIOS/Basic Input Output System.
