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)

    Hi Loner T I read the info you gave me two weeks ago and just followed each step and I was able to fix my problem!  I was travelling for work the past two weeks and I didn't get to thank you.  You are a wizard with computers!  Thanks a lot!

    Excellent. Please create backups for OS X, Windows, and create a Windows System Restore point.

    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.
