Hit ok and start the Gparted Live machine.The next step is to add the disk that you want to resize under the “Controller: SATA” section.Choose the Gparted Live iso you downloaded in step 2. Under “Controller: IDE” add a new optical drive.Go to the settings of the newly created Gparted Live machine.Now we need to attach the Gparted Live Iso file we downloaded in step 2.Call the new machine “Gparted Live”, and choose the type “Linux 2.6 / 3.x / 4.x”.While downloading, go back to VirtualBox, and create a new virtual machine.GParted is a free partition manager that enables you to resize, copy, and move partitions without data loss. In order to resize the partition, we need to work with a partition editor / manager.
Otherwise the extra space would simply be “unused space” or “unallocated space”. Now that we resized the VDI file, we need to resize the partition.
Secondly, it extends the capabilities of your existing computer so that it can run multiple OSes, inside multiple virtual machines, at the same time. What does that mean? For one thing, it installs on your existing Intel or AMD-based computers, whether they are running Windows, Mac OS X, Linux, or Oracle Solaris operating systems (OSes). Oracle VM VirtualBox is a cross-platform virtualization application. Recently I started using VirtualBox in order to install and run multiple operating systems on my laptop for testing purposes.
