Thanks Dan, I disabled Secure Boot and sure enough, the driver was loaded.
I actually decided to make a clean install of Debian on this machine and left Secure boot disabled. I tried multiple times and was unable to get the driver to load. This is strange however because it did work before. I wish I was knowledgeable enough to know what a. b. or c.. actually means, as I said before, I just followed the instructions to create the MOK and enroll it. https://wiki.debian.org/SecureBoot#Virtualbox_Packages I did change "-subj "/CN=My Name/" for -subj "/CN=Myself/" Could that have created an issue? thanks again,
