My two desktop PC's have legacy BIOS. The System reserved has always been added automatically for me when installing Windows 7 and 8.1. I've heard that it won't be if the drive is already partitioned when you install Windows though. If you just format but don't delete any partitions that could happen. I never manually create any partitions on a clean install. I just delete the ones Windows uses and leave my Data partition intact. YMMV I guess.
My "I don't think it matters" comment was in reference to formatting the drive, not the deleting the partitions part.
