    Hello, I was playing around with dual booting Ubuntu on my Macbook Pro and it seems like I accidentally deleted my mac partition. Only ubuntu boots on it now.

    I tried all the recovery startup commands but none of them work, leading me to believe I also deleted the recovery partition.

    Any help in reinstalling OS X on my machine would be greatly appreciated.

    In the middle of several books.
    Do you have a USB installer for Mavericks or Yosemite? If so, you can use that to reinstall the OS.

    If your Mac is a more recent model you should be able to use Internet Recovery to reinstall OS X. You can do this by restarting your Mac and holding down Command-Option-R right after the start up sound.

    More information on Internet Recovery can be found at

    In the event that you are unable to use Internet Recovery, you can always use another Mac to download the OS X installer from the App Store and use a Terminal command to create a USB install disk. More information, along with the required commands can be found at

    Alternatively, you can take your Mac to an Apple store and ask them to reinstall OS X for you. They should be able to help you out.

    Best of luck and have a great day.

    You'll need one that is at least 8 GB in size to create a USB install disk.
