Open the Startup Disk Creation tool by hitting the Windows key and then searching for "startup disk". It should be in the "Downloads" folder after you download it from the Ubuntu website.

Go to the official release page and download the desktop version. The first step is to download the Ubuntu ISO. If you want to install Ubuntu on a virtual machine with VirtualBox, you don't need to create a startup disk you can boot the virtual machine using the ISO directly.
