17. Do you remember when we installed the guest system in the New Virtual Machine wizard, the installation disk was not loaded, which means that the virtual machine does not yet have an operating system. We can load the operating system ISO image file by clicking the "CD/DVD (IDE)" setting in "Edit Virtual machine settings" or directly using the host optical drive installation system (generally recommended to load the ISO system image file) pay special attention to "connection at startup" in the "Device status" check;
