About Bootcamp Partition

When browsing some technology websites or forums, I noticed some users encountered problems about resizing bootcamp partition. Maybe it’s a problem that you have met before or are going to encounter.

Naturally, how to resize bootcamp without deleting Windows and losing data is a hot discussion topic. If you are seeking a suitable approach to solve the issue, this post may be of great use.

On the contrary, even the issue resolved, this article is still worth reading for that it offers a free and effective tool – MiniTool Partition Wizard to address the issue.

So, what exactly is bootcamp? Here is a specific explanation:

Boot Camp Assistant is a multi-boot utility attached to Mac OS X in Apple Inc. helping users install Microsoft Windows operating system on Intel’s Macintosh computers.

The utility instructs you to complete non-destructive disk partitioning of your hard drives or solid state drives (including resizing existing HFS+ partitions if necessary) and installing Windows device drivers for Apple hardware.

The utility also installs the Windows Control Panel applet for selecting a boot operating system. What’s the function of Boot Camp Assistant?

Its main purpose is to help you partition your hard drive and create an essential Windows partition. If you decide to delete Windows at some time, Boot Camp Assistant can restore Mac to a pre-Windows configuration.

How Boot Camp Works

Boot Camp software relies on the startup method that controls Mac. To know this process, let’s look at Mac’s booting process.

Specifically, we need to know how Mac reads and uses its hard disk. How does the Mac know which partition to locate when booting?

In fact, the partition table has an indicator of the partition to use when booting. Your Mac will look for the operating system on this partition. However, if you have both Mac and Windows, you need some methods to make a choice among those partitions.

You have two approaches to switch between Mac and Windows through boot camp Windows 10:

  • Use the Boot Camp utility to instruct you to switch to another partition and then reboot.
  • Use the option key during the white splash screen at startup and then select the partition you want to use.

When to Resize Bootcamp Partition

Boot Camp is a dual boot feature for Mac, allowing you to create separate partitions and run two different operating systems on a single Mac.

This module is mainly used to create a Windows partition on a Mac drive, so you can run the Windows operating system while using your Mac for multiple purposes.

Sometimes the Boot Camp partitions that are originally created require more space, so to scale up, people often format their bootstrapping drives and recreate them with more space.

The Mac actually recommends this process because the disk utility can adjust the size of the HFS+ (Mac OS) partition, but not enough to modify the NTFS partition’s size.

However, it is not always necessary to format the entire drive to adjust the size of the Boot Camp partition. On the contrary, you can choose to take an image of the Windows Boot Camp partition and restore it. This will retail all untouched settings.

In the following content, I will introduce how to change bootcamp partition size. Please follow me to explore it.

How to Resize Bootcamp Partition

In most cases, you can resize Windows partition in Disk Management. Similarly, Mac also comes with its own disk management tool which is called Disk Utility. However, adjusting the Bootcamp partition is not easy.

Given that fact, I will give you specific steps to resize Bootcamp partition.

Step 1: Back up your Windows partition with a third-party tool and save it to the desktop.

Step 2: Delete the old Windows partition and adjust the current Mac partition.

Step 3: After finishing partitioning Mac OS, create a new Windows partition in available space and format to MS-DOS (FAT).

Step 4: Use the disk utility to adjust the boot array partition according to your demand and assign a new name for the partition.

Step 5: Reboot your Mac to obtain a new Windows partition and restore Windows backup partition image you created over newly created Windows partition. A third-party allows you to finish the process with ease.

Step 6: Run the boot disk to check two partitions.

Alternatively, you can choose a third-party tool to resize Bootcamp partition without deleting Windows. MiniTool Partition Wizard is proved to be an excellent partition manager. You can adjust the Bootcamp partition through Extend Partition or Move/Resize Partition feature of this software.

Take the Move/Resize Partition feature as an example:

Step 1: Set Bootcamp as Boot Disk and reboot the Mac.

Step 2: Launch MiniTool Partition Wizard to get its main interface in Windows. After selecting the Bootcamp partition, click Move/Resize Partition in the action panel.

Step 3: Move the handlebar to adjust the Bootcamp partition’s size and location. After that, click OK to continue.

Step 4: Click Apply to execute the operation.

Resizing Bootcamp partition separately seems a little complicate, but it would be easier with a third-party tool. What’s more, you don’t have to delete your Windows with professional software.
