I recently was on Ubuntu 20.04 and tried to download Kali Linux. I must have messed up and it has cause my PC to be stuck on a loading screen on start up that has a pro series logo, a buffer symbol, and ubuntu logo at the bottom. Also the tty 2-6 do not appear when I try to get onto them, its just black screen. When I press Esc on startup it will take me to a grub menu with Kali linux background and menu, although when I try to start from there it takes me back to the same loading screen as before. Anyone have any idea what could be done?
