Also, it is legal for you to transfer the old XP installation to a new computer only if you have a retail license for XP, which costs about twice as much as an OEM license. If the old computer is a typical Dell or HP, then it probably has an OEM license. I only bring this up because you do not mention the type of license on the original computer. I have heard of people talking their Microsoft reps into letting them transfer one OEM license to a new computer, but Microsoft is under no obligation to do that, it specifically violates their OEM End User License Agreement.

Thanks for the tip on Clonezilla. The last open-source imaging program I tried was an old version of Mondo Rescue, that was flaky enough to justify my purchase of Acronis TrueImage Workstation and Workstation Echo.
I don’t think I needed to get rid of old drivers, so long as they’re no longer being used.
