I would like to know how to DUAL BOOT using two different physical hard drives. Is this possible? I currently have a machine running XP Pro with a BUNCH of older apps and custom legacy apps for my company. I don't use this very often, but I will occasionally need to boot up from this hard drive and run this machine in its current state. I am going to put in a separate physical hard drive and install Win 7 (probably) and boot from this drive 80% of the time. How do I accomplish this? What additional software do I need (note: might not use win 7 so it would need to be software that could boot ubuntu or another copy of XP from the second drive as well). I've never done a dual boot before so any instructions or links would be appreciated. Thanks.
