I am running Kali on a Virtual Box VM. everything runs, works, and looks great, except one little tid bit. When ever i power down, it whips the drive, and boots a freshy when i get back in. Save state works if i specifically utilize save state, but if i send the shutdown signal or power off, when it reboots, i no longer have any of the files, folders, programs, or anything that i put on there. any ideas?
