Just installed Fedora 41 using Fedora Media Writer. It worked without issue. I still see two copies of Fedora (24451R802408-WD_BLACK SN770 2TB) in my BIOS boot manager under EFI Boot Devices, so something wonky still seems to be happening, but it works.
I’m going to try rebuilding a Bluefin bootable ISO one more time, and if that doesn’t work I’ll just look for a different distro.
