‘Ghost’ works fine – any drive imager will do. But what you need to make it complete is a copy of Microsoft’s “sysprep” (http://support.microsoft.com/?kbid=838080) which removes the architecture/driver dependencies that you have on your install of XP. After you’ve sysprepped the old laptop, shut it down and ghost the hard drive. Then it’s just a matter of exporting the image to your new laptop and booting. Make sure you have tons of drivers for that laptop on a CD or something though, because XP will want ’em.

That, or get a Mac.
