2nd Windows where? D: will never be a native partition on a first HD primary.

Do you know what makeactive does? Are you sure it does what you need or want 
done?

I can't respond without knowing the partition type bytes for all of them, and

that order is non-standard and apparently out of order. I might even need to 
copy that whole MBR sector to a disk to see what's really going on there.
