Solved How can I format a slave drive that has a primary partition?

[apache64]

I installed Windows7 Home Premium on my SSD drive without reformatting the other drive that originally had it installed. I am now trying to format that drive (D) and keep being denied since it still shows to be, Healthy (System, Active, Primary Partition) in Computer Management. I've tried CMD (as administrator), safe mode with cmd prompt and always get the message "System Partition is not allowed to be formatted".
Can anyone clue me in on getting this drive formatted? Appreciate any help

Always unplug all other HD's when installing an OS. Now you must recover the System boot files into Win7 on the SSD.

Unplug all other HD's, Mark Partition Active. then run Startup Repair - Run 3 Separate Times.

Thank you for the information but I figured it out. I found an outstanding little program (freeware) EaseUS Partition Master 9.1.1 Home Edition. This little jewel allowed me to change it to a logical drive with a right click. It was so simple I could have kicked myself.
Appreciate you support.
