To get to that directory of your hard drive you would need to boot from a live CentOS USB or CD/DVD and mount the /boot partition of your HDD. Try to do this yourself, otherwise ask for help from the lab tutor or instructor.</mathbr><br># For next semester add in procedure for SSDs to create a duplicate image file for c7host in case the original is corrupted.

Do we disable selinux, but have tip box in labs to show how to make exceptions in selinux? - Murray S.<br><br>#Would be nice for consistent assignments.
