How do I dual-boot Ubuntu 18.04 on a 2011 Mac Mini?

Machine Specs:

Mac Mini (Mid 2011), Macmini5,2Core i716 GB RAM (2x8 GB)AMD Radeon HD 6630M 256MB27-inch Apple Thunderbolt Display512 GB SSDRunning macOS 10.13 High Sierra Caution:
This process can result in data loss. If you have personal data on the Mac Mini before starting, back it up first. Twice! (One is none. Two is one. ~ U.S. Navy Seal saying).  Also, mistyping in the parts of this process may brick your Mac Mini. You have been warned. If in doubt, stop working and do research on Google until you understand what's going on in the step. If you find an error, please leave a comment. I will update.
This is process I figured out in lieu of booting the Ubuntu install with EFI via refind. Via the refind boot method, I would constantly get:

10:39:07 kernel: Couldn't get size: 0x800000000000000e
10:39:07 kernel: MODSIGN: Couldn't get UEFI db list
10:39:07 kernel: Couldn't get size: 0x800000000000000e

The error seems to be related to Apple's use of Secure Boot.
