Q: HELP! I tried to put bootcamp on my mac, now i only have windows...

Hi Everyone,

 

So I have an imac, late 2013 model with no disc slot. I wanted to put windows 64 on my mac. So i tried to partitioned my mac with bootcamp. But now I only have windows... If it helps you understand how the problem may occur, I used this website for instruction.

http://www.simplehelp.net/2009/01/15/using-boot-camp-to-install-windows-7-on-you r-mac-the-complete-walkthrough/

 

When I partitioned my mac, I put 100gb for the mac side and the rest for the windows (I need to put my space on the window side for my projects; I have 1TB of storage)

 

I don't know what went wrong but I've put bootcamp on my macbook pro and i know when i start up my mac, I can access my mac or windows. Whereas now on my imac, it starts up with windows and I can only access the windows side. What can i do to just format my computer to how it was initially (latest Yosemite was the version I had) , with just my mac?

 

Should I just bring my imac to Apple and get them to format it back to normal?

 

I'm not tech savvy so excuse my lack of knowledge or terms.

 

Thank you in advance.

iMac (27-inch, Late 2013)

    Hold down the Option key (preferably using a wired USB keyboard) while starting up your Mac. Are you not seeing a choice of disks/systems to use for startup?

     

    Unless all your data and documents are thoroughly backed up to other drives, please don't "reformat" anything.

     

    [BTW, the instructions you used are over six years old.]

    I pressed the Option key (I have the Apple wireless keyboard) It brings me to a black screen with a lock and I have to put in a password... I don't know what it could possibly be, I tried putting in my admin password but it doesn't work.

    Did you enable BitLocker after Windows was installed? If possible, OS X: Installing OS X on an external volume - Apple Support, and boot from this external disk. This will allow your internal disk partitioning to be examined.

     

    You can also try OS X: About OS X Recovery - Apple Support and get to the Recovery Console and check the partitions, but this requires using a camera to take screen shots. You can switch between Terminal and Disk Utility and Safari, but it can be a bit more tedious compared to the first method.

     

    Using either method, can you post the output of the following Terminal commands?

     

    diskutil list

    diskutil cs list

    sudo gpt -vv -r show /dev/disk0

    sudo fdisk /dev/disk0

     

    The "sudo" commands will prompt for your password, and it will not be echoed back. You may also see a warning about improper use of "sudo" and potential data loss due to "abuse" of the command.

    Okay, Actually, I got to a screen where I could choose HD, Windows, or Recovery 10.10.3

    Which one should I select?

     

    I pressed Option when I heard the chime then a black screen with a lock is shown, I put in a password and got to the three options I had said above

    If you see all three, it is good sign. You have FileVault enabled. Choose Windows first, you may to complete the installation. Once Windows has finished installing, install BC drivers, and then test switching between the two OSes.

    I think Windows already finished installing.. What is bc drivers?

     

    Do I click Recovery 10.10.3? because I already have windows installed. I just need to get the mac side to show up..

     

    or Do I download OS X on a external disk? and then plug it into my imac? I don't know how these things work.

    BC Drivers are Bootcamp Drivers. They support Apple-specific hardware on your Mac under Windows. You can see the matrix at System requirements to install Windows on your Mac via Boot Camp - Apple Support.

     

    You do not need to click on Recovery. Click on OSX and verify that OSX boots properly. You can switch between the two OSes using Boot Camp: Set the default operating system.

     

    You do not need to install OSX on an external drive, but I suggest you have good back ups of both OSes on external drives, for recovery purposes.
