I've made a minor change to Step 3. Restore Factory Defaults and Configure the BIOS of the guide.
Since I originally wrote the guide last June with a Nvidia GT640 card, I had Legacy support enabled in BIOS. I swapped that out later after the install and post install was complete. I recently tested booting the installer for Sierra again with a GTX 1050 and the install and post install are much more user friendly with Legacy Support disabled under the Security tab in the BIOS. This is similar to disabling CSM support in Haswell or newer systems. CSM allows you to boot legacy drives while also booting UEFI with other drives in the same PC. Here's the official definition of CSM:
The Compatibility Support Module (CSM) is a component of the UEFI firmware that provides legacy BIOS compatibility by emulating a BIOS environment, allowing legacy operating systems and some option ROMs that do not support UEFI to still be used.
So for everyone with a UEFI capable graphics card this is the best way to go. Examples are GT710 GTX 1030 and 1050.
Disable legacy support in BIOS. This should also work with Windows installed UEFI in a dual boot setup, but I haven't tested that. Leave a note if you are a Windows dual booter and try this out. TIA
