If you keep getting errors, I think it said something like unrecoverable fault or a problem encrypting the drive, just reboot and use the graphics safe install option at the beginning. After it installs, go to the "Software & Updates" app and install the proper NVIDIA driver to resolve any display issues.
Not sure if this was because of secure boot or just a general NVIDIA annoyance, but that was the fix for me.
Also, try to avoid installing Fedora on another drive. I have no idea how but it totally messed up the audio on Zorin. Zorin is wayyyyyyyyyyyyy better anyway, especially for NVIDIA.
