Check the SHA256 checksum of your downloaded .iso against the value listed on Zorin website. Ref: Before you install
Also check Secure Boot (BIOS) and Fast Start (Windows) are disabled before installing Zorin.
Maybe try a different USB burner than Etcher, e.g. Rufus or Unetbootin.
There maybe a good case not to add additional driver updates at time of install, but do that after. Others here may advise you better on that matter, particularly for Nvidia.
