Well, it looks like "Rogers laptop C Drive" was the volume label of drive C: in the old laptop. You could open Explorer on the new laptop (after exiting TP7 there), right-click on drive C: and pick Properties from the bottom of the context menu that appears, then change its name to "Rogers laptop C Drive" (without the quotes) too. Then launch TP7 to see if that did the trick.
According to TP7's documentation it also uses the drive serial number to match fixed drives, but I don't think that's correct. And where the computer name is concerned, I think that's used only for images that were thumbnailed through a network. So, I'm hopeful that just editing the volume label will solve this problem for you.
