hello community I am about to receive a new computer with no OS on the hard drive. I plan to install Windows 7 Professional x64 on it and I was wondering if i need to create separate partitions. I see many places saying creating system and data partitions is the smart way to go, yet I don't completely understand how or why. If anyone could explain to me why it's necessary and a good way to go about partitioning the hard drive that would be great!
