Because when you installed 7, you left your old HD in, so the 7 installer saw it, and information was written to the MBR on the current boot disk (your XP one)..

If you had installed 7 with only the new disk installed, it wouldn't have done that.

No panic. Just unplug the old disk, run the 7 install again, select repair, and it will put the MBR on the new drive..
