If you’ve installed Windows via Boot Camp, and now want to delete it and restore the space to your main Mac hard drive, this brief tutorial will guide you through the steps to do just that.
It’s actually quite easy to remove the Windows drive and reclaim all the hard drive space, the only “problem” is that Apple doesn’t make it a particularly clear process.
NOTE: by deleting your Windows Boot Camp partition, you will of course be deleting all of the data on that partition. Make sure to back up anything on your “Windows drive” before you proceed. Your macOS partition will not be erased and you won’t lose any data from it.
If for any reason the following steps don’t work, there’s a link at the end of this tutorial that will take you step by step through deleting any partition on your Mac, and restoring the space to your primary one.
- Launch the Boot Camp Assistant by going to your Applications -> Utilities -> Boot Camp Assistant.
- Click Continue on the initial Boot Camp Assistant Introduction window.
- Select Remove Windows 10 or later version and then click Continue
- Click the Restore button to delete the Windows Boot Camp partition and restore the disk to a single-partition macOS volume.
- You’ll be prompted to enter your password – do so and then click OK.
- That’s it – Windows is gone. Click the Quit button.
If for any reason this method didn’t work, see the tutorial titled How to Properly Delete a Partition in macOS (which involves rebooting) but will delete any partition and restore it to the primary.
