When to create a partition from C drive?

I just received a new laptop, and for some reason, the manufacturer decided that one great C: drive and no other (user available) partitions were the way to go. I would like to have two partitions - one for OS/Program files and one for my personal data (documents, photos etc.).”

Have you ever confronted the same situation that this user had in Windows 7? Maybe you got more than one partition on the hard drive yet in a big C: drive with redundant space, and you want to split partition C to get some space for other purposes. Maybe you have to shrink C drive for other reasons. Anyway, how to create partition in Windows 7 from C drive is what you need to consider next. 

Tips: whenever you try to do something on your hard drive, please back up disk first in case something bad happens. You cannot be more careful with your data even though this operation has no harm to it.

How to create new partition in Windows 7 from C drive?

To use Disk Management to create a partition from C drive, you need to create unallocated space first, and then create a new partition based on it.

First, right-click the Computer icon in the desktop, select Manage, and then click Disk Management. Right-click C drive, and select Shrink Partition. It will query volume for available shrink space for a while.

Note: In the wizard, the new partition will be formatted, and you are able to choose the file system (NTFS by default) in the same window. If you choose exFAT at first, you can convert it to NTFS later. While if you choose NTFS first, you cannot convert it to exFAT later.

Just within four clicks, you can create one another partition from C drive in Windows 7 using Disk Management. However, in most cases you cannot shrink C drive beyond half through this way. For instance, if you have a 700 GB partition with 500 GB free space. You can only shrink this partition by 350 GB or less. The corresponding reason is the size of the available shrink space can be restricted by the amount of space currently allocated to the hard drive for the virtual memory page file, system protection maximum storage space size, and hibernation files. If you are unlucky to encounter this situation, then ask 3rd party software for help is a wise choice under this circumstance.
