Buy a new Windows 7 PC and it will ship with the operating system pre-installed, as you would expect. Problem is that the configuration is the same across every computer that the manufacturer ships from their factory. Often one large hard drive formatted as one partition or, more likely, sub-divided in to partitions in a manner the manufacturer deems most applicable for its customers.
This doesn’t necessarily suit your requirements and it means that the first thing you’ll want to do is create your own partitions before you start migrating your data from your old PC. The partitioning tools supplied with Windows aren’t great. It’s difficult to merge partitions and impossible to make changes to your system partition whilst you are using Windows.
Until recently, getting hold of partitioning software meant you nearly always had to spend money on commercial software. Now there are free applications for home users that enable you to do most of the partitioning tasks you require: create, delete, merge and enlargen existing partitions.
Partition Wizard Bootable CD is a disc which enables you to boot in to an operating system where you can create, merge and enlargen a system partition, without it affecting your Windows installation.
