When you select a custom configuration, the New Virtual Machine wizard prompts you to configure a hard disk for the virtual machine.

Virtual hard disks are the best choice for most virtual machines because they are easy to set up and can be moved to new locations on the same host system or to different host systems. In a typical configuration, Workstation creates a new virtual hard disk for the virtual machine.

In some cases, you might want to select an existing virtual hard disk or give the virtual machine access to a physical hard disk or unused partition on the host system.

If you instruct the New Virtual Machine wizard to create a new virtual disk during a custom configuration, the wizard prompts you to select the virtual hard disk type for the virtual machine.

During a custom configuration, if you instruct the New Virtual Machine wizard to create a new virtual disk, use an existing virtual disk, or use a physical disk, the wizard prompts you for the name and location of a virtual disk (.vmdk) file.
