Q: Repairing Boot Camp after creating new partition

Hi


I'm running OS X 10.9 and Windows 7 x64 Pro.

 

I set up Boot Camp to dual-boot Windows on my MacBook Pro Retina. Everything was fine. And just yesterday Apple released the Yosemite Beta for the public and I wanted to download this and give it a try. After some research, I found that creating a separate partition was the way to go, and so I made another partition.

I wasn't aware that this would affect my Windows partition as I thought it was completely different.


So now, when I boot up, there is no option to boot with Windows. But when I boot the Mac and select Startup Disk, it shows Boot Camp is still there and all my files etc are still there.


I have a 256SSD, 160GB was for the Mac, and I have 90GB set for Windows.


I made the new partition to 40GB (and the Mac was now 120GB).

 

Then once I completed that part, I restarted my Mac and the Windows boot option was no longer there.

 

I didn't even install the Yosemite yet. I went to Disk Utility and deleted the 40GB partition that I made.

 

Now I don't know what to do. I have a lot of important things which are still on my Windows. Is there a way to restore normal Boot Camp functionality?

MacBook Pro (Retina, 13-inch, Late 2013), OS X Mavericks (10.9.4)

    I have an iMac (Mid 2011) with El Capitan and W10, so i guess i should be using a shared external disk?

     

    I have another question, but i don't want to go off topic here.

    Hello Loner T,

     

    I tried following your steps but once I get to the "write" portion, it tells me I don't have permission even though I am the Admin AND I entered the password at the start of the commands. Any help will be greatly appreciated!        Screen Shot 2015-11-05 at 6.16.28 PM.pngScreen Shot 2015-11-05 at 6.15.25 PM.png

    1. You may want to start a new discussion to avoid confusion.

    2. You have El Capitan, which has System Integrity Protection (SIP) which needs to be disabled.

     

    Use the  following steps.

     

    1. Boot into Local Recovery (Command+R) during power up.

    2. Run Utilities -> Terminal.

    3. Type csrutil disable and press return/enter.

    4. Boot normally.

    5. Type csrutil status in OSX Terminal and verify that is it disabled. If still enabled, repeat.

    Here's the new Discussion: Bootcamp won't boot after adding partition to HDD

    I tried to disable the SIP several times. In the Local Recovery, it says I disabled it successfully yet when I check the status it says it is still enabled?

    Hi Loner T,  I have the same problem as MattTheMedic.  It's been a long time since you helped him but can you help me.  I follow everything you state but when I get to the "write" command (or "w") I get a message saying fdisk: /dev/disk0: Operation not permitted

     

    Do you know what I can do?  I have Mavrick installed in my mac book pro and I have windows on my bootcamp side.  I deleted the extra partition I made already and I will not do this again.  Can you help me? Please

    I followed these steps:

    2. 2. sudo fdisk /dev/<DiskWhereYouHaveInstalledBootcamp>
    3. 3. sudo gpt -v -r show /dev/<DiskWhereYouHaveInstalledBootcamp>

    sudo fdisk -e /dev/disk0

    setpid 4

    flag 4

    write

    It may be better to start a new discussion and post details of the current state.

    Hi Loner T,

     

    I have the same issue as the original poster, and I'm assuming your string of fdisk commands will work in my case, but I'd like to be sure before destroying something. To not clutter this thread, I've started a new one with the output to the commands you requested. Any chance you could take a look here: Windows Missing from Boot Screen?

     

    Thank you in advance!

    Can you post a new discussion and include 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.

    Please post a new discussion in Bootcamp forum. See Find answers and ask new questions for help.

    So I went ahead and started a new discussion. You can find it here: Disk utility repair made Bootcamp partition innacessable.

     

    Thanks so much for your assistance!
