I don't mean to be cynical when i say this: with all the brains out there, you would think someone could have figured this out before and made a post about it. So, here I am making a post about it. Let's get to business.

The general steps are:
  1. Format the drive in FAT32.
  2. Copy the install and isolinux folders from the ISO image to the thumb drive.
  3. Rename the isolinux folder to 'syslinux'.
  4. Rename the 'isolinux.cfg' file in the new 'syslinux' folder to 'syslinux.cfg'.
  5. Run syslinux against the USB drive to give it a boot sector and make it active.
  6. Copy the Zentyal ISO image to the thumb drive.
  7. Boot from the thumb drive. Let it fail and bring you to a 'boot:' prompt.
  8. Press Enter to begin the setup process.
  9. At the part where it can't find the CD-ROM device, tell it you'll specify the device manually.
  10. Use an alternate terminal (Alt+F2) and mount the USB drive.
  11. Return to the setup process (Alt+F1) and enter the path to the ISO image on the USB drive.
  12. Continue setup and rejoice in your recent accomplishment.

Note: When it asks to dismount other mounted volumes tell it Yes. It won't break like you think it will.

Edit: I corrected instruction 5, re-wrote 10, and added a link to the Syslinux Project site and the MAN page for the Linux 'mount' command.
