Different Chris, but... it sounds like Windows gets a "fallback"
position for when the firmware has no boot entries; is there a way to
get Fedora into that position instead (in a dual-boot setup)? Or is it
a case of the firmware just explicitly looking for the Windows loader?
As a fun fact, my Dell laptop seems to have some code somewhere (likely in the BIOS itself) that when there are no boot options setup when I try to boot form the main disk it will run an auto detect mode that likely looks into the ESP and finds the boot options from there.
I had to clear all boot options for testing a few times (as well as due to changing SSDs) and I noticed that it not only is able to find the boot options for a Windows + Linux dual boot as well as Fedora only.
Though also, yes, a "Windows Boot Manager" option might be chosen as the default sometimes, likely as most users are expected to be using Windows.
