How to Remove a Boot Camp Partition From Your Mac

What is the Boot Camp partition?

Software incompatibility may force some Mac users to take the ultimate step and install Windows on their computer using Boot Camp. As with every operating system, Windows requires its own partition and its own file systems, which means to use it on a Mac requires you to repartition the drive using Boot Camp assistant in order to install the Windows operating system.

If you are installing Windows for the first time, you will require at least 30GB of free space, increasing to 40GB if you are upgrading from a previous version of Windows. This space will be taken up on the built-in hard drive (which may have limited storage space), allocated to the Windows OS during the installation process. This newly created partition will be named Boot Camp by default.

Regardless of how much disk space you have allocated to Windows, it is nothing more than a waste of storage if your startup disk is getting full, and so in these situations it is recommended that users either wipe away the macOS partition using Mac optimization software such as CleanMyMac, OnyX, and the like, or remove the Boot Camp partition to reclaim gigabytes of disk space.

Some users complain about receiving the “Your disk could not be restored to a single partition” error message, and therefore being prevented from restoring the internal drive back to a single partition. If, for some reason, Boot Camp fails to remove the partition, then you can always turn to Disk Utility, a powerful tool built into macOS.
