  • After setting the size, click “Create”.


You’ve now allocated the primary resources needed for your Ubuntu VM: RAM, CPU, and storage. These steps are crucial in ensuring that your VM operates efficiently without overburdening your host system. Remember, the exact allocations might vary based on your computer’s total resources and your specific needs.

Next, you will proceed with configuring additional settings for your VM, such as network and display options, before moving on to the installation of Ubuntu itself.

After allocating basic resources like RAM and CPU to your new Ubuntu virtual machine (VM) in VirtualBox, the next step focuses on setting up the virtual machine’s storage. This involves creating a virtual hard disk, which acts as the VM’s primary storage device where the operating system (OS), applications, and data will reside. Let’s dive into the specifics of configuring the virtual hard disk.

Setting Up Storage for Your Ubuntu Virtual Machine

Creating a Virtual Hard Disk

  1. Virtual Hard Disk Introduction: When you reach the storage configuration step in the VM creation wizard (following the allocation of RAM), you’re prompted to either create a new virtual hard disk or use an existing one. Since we’re setting up a new VM, you’ll choose to create a new disk.
  2. Choose Hard Disk File Type:
  • VDI (VirtualBox Disk Image): This is VirtualBox’s native disk format and is ideal for most users. It’s flexible and easily portable.
  • Select VDI and click “Next”.
  1. Storage Details:
  • Dynamically Allocated vs. Fixed Size:
    • Dynamically Allocated: A dynamically allocated disk file will only use space on your physical hard disk as it fills up (up to a maximum fixed size). Although this method saves physical disk space, it might slightly reduce performance.
    • Fixed Size: A fixed-size disk may take longer to create on some systems but is often faster to use than a dynamically allocated disk. The file size of a fixed disk does not grow over time. It allocates all the space you specify for the virtual disk at the time of creation.
  • Choose according to your preference, but for most users, “Dynamically Allocated” is sufficient and more efficient in terms of physical disk space usage.
  1. File Location and Size:
  • Location: By default, VirtualBox will create the virtual hard disk file in the VM’s folder, but you can choose a different location if your primary drive is low on space.
  • Size: For Ubuntu, a minimum of 25GB is recommended, but 50GB or more is preferable if you plan to use the VM extensively. This space needs to accommodate the OS, software installations, and user data.
  • After setting the location and size, click “Create” to finalize the virtual hard disk setup.
