I've tried 10.1 and 10.2. I have one hard drive for linux, and one drive for Vista x64.
Grub installs fine on the vista hard drive, but then it fails to make an entry for vista for 10.1 or 10.2 (with an nforce4 mobo and SATAII WD HDD's)
I just go into /boot/grub/menu.lst and make an entry for vista like it says
here. Everything works as it should.
Note that I enter "hd0,0" instead of "sd0,0" even though my drives are SATA, for some reason that's the only way it works.
Your setup might have to be set up differently, but I just wanted to add what my experience with dual booting vista/linux was.
