Endless Reboot Loop Due to macOS High Sierra Update

Problem

The IT User Support Group has had several calls from customers this morning regarding the endless reboot loop of their system after installing the latest High Sierra macOS update. Error message is,

The system then enters an endless reboot and does not let you log into the computer.
