The only software I have used that CONSISTENTLY and RELIABLY shrunk an NTFS partition to make room for dual boot (installation of another OS), has been ParttionMagic 8.0. Unfortunately, it is only available for win32. It will NOT run on win64. I know, because I tried it!
Since the OP's system will come with Win7 he may as well just shrink it using the Win7 utilities.
