Hello sakamoto motoharu,
You should investigate Wingrub, (Grub for Windows) WINGRB0206.EXE from http://sourceforge.net/projects/grub4dos
WinGrub web forums, http://sourceforge.net/forum/?group_id=104188

I have a hobby if trying out various bootloaders and I have WinGrub in one of my computers, it works fine for me. It seems to match your criteria.
I had only one problem with it, I found I could not use it to boot a Linux installation with Grub when the other Grub it has to chainload uses the 'savedefault' command. As long as that command is commented out (disabled), Wingrub works very well, I have been using it for quite a while now.
The documentatioin for WinGrub is a bit sketchy. I have made my own webpage about how I set up Wingrub, that might help you. Here is the link, http://users.bigpond.net.au/hermanzone/p9.html

If you are using Vista, EasyBCD would probably be better, http://neosmart.net/dl.php?id=1
