Are C and D partitions or separate drives?

 

[unksol]

Boot into windows 8 and format the drive with windows 7

Easiest way to do it in my opinion is to run a linux live cd and run gparted to erase the partition that has windows 7

Nah, boot W7, dos window (Run As Admin) and run bcdedit, remove W8 from boot menu and then format D: from within W7.
