How to Make VirtualBox Screen Bigger: A Step-by-Step Guide

If you’re running Windows 10 in VirtualBox, you might be familiar with the frustration of having a small screen that you can’t seem to make bigger. Fortunately, there’s a solution to this problem. In this guide, we will walk you through the steps to make your VirtualBox screen bigger.

First, log in to your Windows 10 machine in VirtualBox. Then, navigate to the devices tab and click on “Insert Guest Additions CD Image.” This will mount a CD that contains some tools that we need to install on the guest operating system.

Once the CD is mounted, go to File Explorer and see if there is something mounted on the D Drive. Click on the VirtualBox guest additions and run the Box Windows additions amd64. This should install the tools on your VirtualBox machine.

During the installation, you can select the default options. After the installation is complete, you should have drag and drop capability from the host to the guest and vice versa. You should also be able to resize the screen to any size you want, and the guest operating system should automatically adjust to fit the screen.

Once the installation is complete, reboot your machine. After it’s rebooted, log back in, and your VirtualBox should be automatically in full-screen mode. If you move the screen around, it should automatically rescale to fit the new size.

If you’re still having trouble, make sure that you move your virtual machines to an SSD. This will speed things up and reduce the lag.

In summary, making your VirtualBox screen bigger is easy if you follow these simple steps. By installing the Guest Additions tools and selecting the default options during installation, you can enjoy a full-screen view of your Windows 10 machine in VirtualBox.
