Okay basically I just discovered that due to some mishap, my system partition is NOT the partition of which my OS is installed. Hence I cannot format that partition (Even though its empty).
Here's a screenshot of disk managment.

Disk1 is my primary HDD. You can see that Drive "D" is the System drive and Vista is installed on drive "C". Also what does the green rectangle signify?
What I'd like to do is, make Drive C the system partition and format drive D (i.e. make it a primary partition).
Thanks!
