I run into this issue literally all the time, if you try to install ubuntu on an Nvidia graphics card you may need to use the “nomodeset” string in your grub menu before booting until you can install graphics drivers for your graphics card. Press “e” with either “try ubuntu” or “install ubuntu”, a new screen will appear then simply fine the string “quiet splash” and type “nomodeset” beforehand, you should now be able to get into the operating system with a basic graphics driver, this option is temporary so you’ll likely need to use it again once Ubuntu is…
