Some here might think I am nuts for suggesting this, but I boot both Suse and Windows. I also have a partition I have set aside specifically for trying out other distros and maby BSD some day. Any way I have found that using the open source boot manager GAG to be great for this as it is seperate from any os and is easily replaced if need be. It also will boot any Nix OS running grub in my trial partition, doesn't mater what Linux I install the GAG I have installed just loads the distro's Grub or Lilo (I either set it for default with a 0 seccond boot or 2 secconds depending on the options it has for mem test or failsafe). Once GAG is installed to the mbr and is set to boot XP and 2 partitions with Grub installed to them I need never touch GAG again, unless I have to reinstall XP of course, but then my GAG configure can be saved to flopy or simply reinstalled from the boot flopy or cd image. The only thing to do is to place both your nix's grub to the boot sectors of thier perspective partitions. Realy it is a great boot manager and can boot just about anything, and any number of OSs.
