... have anything to do with this ...Step 5
Now reboot your computer and press f2 to enter UEFI setup (Some computers use a different key to enter setup). Then add your new fat32 partition as a boot option. Unfortunately this process varies quite a bit.
For this particular laptop you have to disable secure boot to use the "File Browser Add Boot Option", then re-enable it when your done. Again this process varies a lot. Generally on the boot tab you will find some way to add a new boot option. After you find the button to to add a boot option, you will be asked to select a partition. This is kind of cryptic as well, and might take some guessing. Then you will be asked to browse to a bootable EFI application, this will be EFI/boot/bootx64.efi on your new fat32 partition. If you can't browse to that path or you can't see the files that you put in your fat32 partition under EFI/boot/, you probably picked the wrong partition. After you have added your new boot option, move that new boot option to the top of the boot order. Again, this will vary with different UEFI implementations. Then save and reboot.
