Unplug disk 0

swap the data/sata cables so your C partition ( windows ) is on sata port 1 on your motherboard.

Run startup repair until disk 1 is booting on its own

Startup Repair

System Repair Disc - Create

post back when you get that done.

After that hook up the D partition drive to sata port 2 on the motherboard and mark it inactive from windows.

Partition - Mark as Inactive

You should now be able to format the D drive.

Do all that correctly and you should be good to go.

If that`s a windows 7 install disc you have there in your dvd drive, then you can use that to run startup repair.

Another option you have available once you have the intended 7 drive plugged into sata port #1 is to boot live from the 7 if you have that and run the command prompt option found in the repair tools there following the tutorial on the Bootrec.exe tool.
