Format the hard drive before you install windows on it and it wont create the 100mb partition. Its not safe to delete it if its already there because it contains your bootmanager. You can delete it and expand the main partition but windows will not boot. To make it boot again you have to run the recovery disc boot repair and it will install the bootmanager to the main partition. EDIT:Oh and yeah daz's loader is the best around at the moment.
actually, it creates 100mb i woudnt mind, but cant windows just "hide" it? it irrates my eyes everytime i want to access my files : [
yes, usually i arrange my files C for OS D for Musics E for games but now suddenly a new partition came up D: reserved space ( damn ) now it becomes C: Os D: reserved space E: music F: games
Windows 7 always hides that partition by default for me, and most other people as well. You might be able to use the Disk Manager to remove the drive letter, and then you won't see it again.
