So I bought this desktop from dell a couple months back and was disgusted with Vista. So I bought another SATA hard drive and installed XP and set the original hard drive aside. Now that I'm a little more comfortable with Vista I'd like to start using it sometimes. So to make the long story longer here's what I'd like to do...

Make it a dual boot system with both drives present and have the boot menu show up and I can choose to boot XP or Vista.

I'm sure I can accomplish this by modifying the Boot.ini on one of the installs but have never done this. so any help would be appreciated.
