How to Delete a Boot Camp Partition

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 OS X 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.

  1. Launch the Boot Camp Assistant by going to your Applications -> Utilities -> Boot Camp Assistant.
  2. a Finder window with the Utilities folder displayed

  1. That’s awesome! Thank you so much for posting this! Just took me about 30-45 seconds and bam! windows is gone!

  2. EXCELLENT!!! I do not know why I ever installed windows on my mac! What a waste of time that was! So glad windows is finally off! Thanks!

  3. Do you have to delete Windows 7 operating system before you remove the windows partition? Or will that be part of all that is removed?

  4. Thank you for your assistance. Got rid of the windows junk and got a clean mac disc in return. Great tutorial.

  5. Dear Ross, I have a problem. As smart as I am, I’ve followed this tutorial, but forgot to uncheck to automatically boot into Mac. Therefore, I am stuck, while holding down the command key during the booting process, because there is a code to fill in, which I have never used!(because I never used the windows part of my Mac). But if i don’t hold the command button, it gives me a grey folder in the booting background with an interrogation mark on it. So, if you may please, would you kindly send a solution to this problem? Thank you very much!

    After scratching my head for a while I came across your help and bingo, I am back in business. I had to remove win 7 from my Mac because I have it now on a new Toshiba.
    Thanks a million for your help.
    Cheers
    Herb
