/Library/Extensions or /System/Library/Extensions on the system partition.
Given that you upgraded from Yosemite then /System/Library/Extensions is the likely candidate.
Excellent! Mounting the drive as an external drive on another Mac and removing the EvOreboot.kext from /System/Library/Extensions was a success! I was finally able to boot up and complete the installation of High Sierra.
Many thanks P1LGRIM!!
