I have set up two partitions on a 500GB hard drive one 336GB (E) and the other 128GB (D) after installing the first OS ,Win&, another partition appeared “system reserved” 100MB showed up. All three partitions say healthy. I installed Win 7 first from a repair disk I made on the (D partition and it showed Healthy (boot) until I installed Win XP. On the (E partition. Now (D only shows healthy and the (E shows healthy (boot) and I can’t boot the Win7 partition.
