I run both XP Pro 32, and W7 64, it's easy and then you will be equipped to handle pretty much any application out there. Here is a link on how to install both, and how to use Partition Master, (real easy to use) but the Freeware version only runs under 32-bit, sooo...just DL it and install in your XP OS, run it, and set a new i.e. "blank" partition for W7 64, then shut down and reboot with your W7 DVD in the drive to boot from, W7 will ask if you want to upgrade or install a new OS, select "New" then it will show the new "unallocated partition", slect that one and let her rip..!!

Here is a good link to show you how...!!! You can Google "Partition Master", the standard one is free everywhere, also it is a newer version than the video suggests...
