Add a partition to hard drive in Windows XP\Vista\7\8\8.1\10 is a good idea when you want to separate your hard disk into different parts for storage, that is, a new partition added could be used as an extra storage medium for backing up important files which is a precaution in case one fails. In addition, if dualboot is what you need, add a new partition can be helpful for you to try a new operating system without overwriting your main Windows drive.
Here, one thing you should notice when you add partition to hard drive - whether your disk is MBR or not. MBR disk only supports 4 primary partitions at most, if you want to have more partition on it, you should make one partition an extended partition first and then create partition on hard drive known as logical partition. However, when you want to have dual systems, you must create a primary partition to store system files since system can only be booted in primary partition, if not, you'd better convert MBR to GPTwhich supports 128 partitions and all of them are similar to primary partition of MBR disk.
