First, verify your ISO image (check the hash of the image as described here) Flash the elementaryOS iso again on another USB (if possible).

If that doesn't help, next step is to boot into live session, go to the /boot/efi and rename grubx64.efi to mmx64.efi as answered here.

Another solution I found on this forum, where he used 2 USB keys to boot from one and install from another.


Make Elementary OS Bootable USB drive by: Steps

  1. Download Etcher / Balena Etcher
  2. Get the Elementary OS ISO files
  3. Run Etcher and add ISO image
  4. Bootable Elementary OS USB drive is ready
