I recently installed windows 7 on a new 3gb HDD. I set aside 60gb for boot and that was all i remember doing.
When I ran windows, it said I had only 60gb on that disk, I'm a noob so I freaked out a bit. I searched forums and learned to use disk manager. When I entered disk manager, the disk was already split into three volumes, the aforementioned 60gb boot, 2tb, and a 750gb. I right clicked the 2tb volume and created new partition.
