I’ve also got the Linux Basics for Hackers book but it’s at home while I’m on vacation.
I’m just really happy rn yall :) this install took some work, SecureBoot kept getting in the way and I’m not the most savvy person so there was a lot of Googling and trial and error in the way of getting here.
Different distros deal with securebot differently. If you try OpenSUSE, secureboot works: you will be asked to enroll your keys after the install reboot. And you will see the ooensuse-secureboot entry in the UEFI boot order list.
