Hello, I am new to using Kali and I am having an issue with my installation. I was able to go through and complete the graphical installation on my VirtualBox machine up to the reboot needed to load the installation. As soon as my machine reboots, after the virtualbox loading screen, I am stuck with a black screen with a flashing underscore. I waited to see if it was just delaying in loading, but after an hour it still would not load. I really want to use this service, but I don't know how to fix this.
