At the Gnu Grub screen, type the word exit and hit the enter key. Then relay whatever is reported in that screen here.

Mine just keeps repeating the line "grub>"

This usually means that the bootloader is faulty or cannot be found.
Are you able to boot into the LiveUSB for Zorin OS (Or any other distro of your choice) and access Gparted to inspect your EFI partition?
