So, while programming today I got the terminal error saying that ls was not available and to type in some sudo command to get it. I typed in said sudo command and it told me that it didn't work. I am new to linux and so I can't give more information than that. Now, when I attempt to boot linux I get "file not found. grub rescue>" prompt. I have no idea what that means or what to do. I have tried putting commands into the grub prompt that Fedora likes but to no avail. I am using Ubuntu on a virtual disk with VirtualBox.
