In general, when it comes to talking about resizing Bootcamp partition, these following questions would be asked: what is Bootcamp partition, when need to change Bootcamp partition size, how to increase/ decrease Bootcamp partition effectively. Next, let's answer these problems in detail.

What Is Bootcamp

Boot Camp Assistant is a multi-boot utility included with Apple Inc.'s OS X that assists users in installing Microsoft Windows operating systems on Intel-based Macintosh computers.

The utility guides users through non-destructive disk partitioning (including resizing of an existing HFS+ partition, if necessary) of their hard disk drive and installation of Windows device drivers for the Apple hardware.

The utility also installs a Windows Control Panel applet for selecting the boot operating system.

In a word, Boot Camp can help partition your hard drive into 2 partitions. One partition will be used by your Mac to run Mac OS X and the other one will be used to run Windows OS.

However, do you know why we have to make a new partition to install Windows? Well, the reason is that Windows and Mac don’t run in the same format. Mac runs on Mac OS X (Journaled), and Windows runs on NTFS.

Partitioning splits your hard drive into 2 separate sections, each with its own format. This means that you can run Windows OS on NTFS and run Mac on Mac OS X (Journaled) on the same hard drive. Of course, this NTFS partition is called Bootcamp partition which is used to install Windows.

You can read How to install Windows using Boot Camp to know details about installing Windows OS on Mac computer.

When Need to Resize Bootcamp Partition

You can firstly specific the size of Bootcamp partition, and then install Windows on it. However, after running Windows, you may find that your Bootcamp partition is running out of space, and you need to increase its size to continue running Windows OS.

Now, the question is: “How to change the size of Bootcamp partition to meet the needs of Windows?”

Well today, I’m going to make it easy for you.

How to Resize Bootcamp Partition

As we know, if you want to resize Mac partition, you can directly turn to the Disk Utility tool, located in /Applications/Utilities. With this tool, you can grow or shrink HFS+ (Mac OS X) partitions on the fly, with the resizing done live regardless of whether the drive is internal or an external drive, or even the boot volume.

However, Disk Utility can not be used to extend or shrink Bootcamp partition since it is Windows NTFS file system partition. So, it is not an easy task to resize Bootcamp partition.

According to Apple: “If your Windows partition is too small, back up the information on it, delete it, create a larger partition, and then reinstall Windows.” Details are shown here.

Traditional Method: Delete Bootcamp Partition, then Create a New Large One

Step 1: Back up all the information on your Windows partition.

Step 2: Delete Windows from your Mac.

• Start up your Mac in OS X.
• Open Disk Utility. (To access the Disk Utility in Mac OS X, just press Command+Space to open Spotlight search, type Disk Utility, and press Enter. You can also click the Launchpad icon on your dock, click the Other folder, and click Disk Utility.)
• Select the Windows disk, click Erase, choose the Mac OS Extended (Journaled) format, and then click the Erase button. (picture is below)

Step 3: Shrink Mac partition to release more free space.

Step 4: Create a new large Windows partition in the free space.

• Select the drive.
• Select the Partition tab
• Click + to add a partition

Step 5: Restore the information you backed up.

On the other hand, with the development of software technology, some software (like Camptune X, Winclone) can help you to resize Bootcamp Partition. And, each tool has its advantages.

To be specific, those familiar with Winclone are aware that with its help you can create a larger Bootcamp partition without losing your original Windows data.

The process involves creating an image of the partition for safe keeping, deleting the original Bootcamp partition with Disk Utility, creating a new, more expansive partition, and then moving the data from the imaged partition to the new one with WinClone.

Although this method is capable enough to enlarge your Bootcamp partition size, you have to delete Windows at first.

Now, you might be wondering:

4. Check to see if the problem is resolved.
