Confirmed: Can run .elfs off HDD without creating partition
I wanted to save some space on my mc so using Launchelf, I was able to move my HDADVANC.ELF off my MC to my HDD in the folder of the HD Loader settings without creating another partition. I thought I'd share this with those wondering. I saved about 800kb this way. If there are any other .elfs I wanted to run I could put them on my HDD this way from a thumbdrive or something. Launchelf is the way to go! This is on an unmodded system also.
