Q: Yosemite Upgrade Broke Bootcamp

Upgraded to Yosemite and now when I ALT Boot Windows 7 and Recovery partitions no longer show up. Using information from other threads I managed to get my Windows 7 partition to show up but when I select it I receive an ERROR READING DISK message. Is there any way to get this fixed?

    You seem to have the same issue. I am glad the bug is consistent, so I know how to solve it.

     

    One more test to confirm that it is the same issue, please post the output of sudo dd if=/dev/rdisk0s4 count=1 2>/dev/null | hexdump -C.

     

    Then gap between GPT#3 and GPT#4 is where your NTFS header is most likely to be. Once you post the output, if you are comfortable I can point you to a thread which solves the same problem, if you are comfortable with some Terminal gymnastics and Testdisk and GPT Fdisk.

    Try the simple first step first to see if it works.

     

    sudo fdisk -e /dev/disk0

    setpid 4

    07

    flag 4

    p

    w

    y

     

    Reboot.

     

    Test 1 - Can you see Bootcamp Volume in Finder?

    Test 2 - Can you files in the Bootcamp Volume?

    Test 3 - Can you select Bootcamp in System Preferences -> Startup Disk.

    Test 4 - If Test1,2,3 succeed, select Bootcamp and click Restart. Does Windows come up?

     

    If it does not, the NTFS header you found using dd is bogus.

     

    This thread has gone through the same issue - bootcamp not working after yosemite install.

     

    If you are uncomfortable using it, I can explain the steps individually to start the rebuild process.

    I tried the steps and don't see the Bootcamp partition in Finder. If you'd be willing to walk me through that would be great. I really appreciate it!

    1. Please post the output of sudo fdisk /dev/disk0.

    2. Are you saying the previous steps did not work in OSX Terminal, or you executed them and still cannot see any change?

    3. If the steps were executed successfully, but no change happened for Windows, then the linked article is where you should start. Are the steps in the linked article where you are running into an issue?

    2. Are you saying the previous steps did not work in OSX Terminal, or you executed them and still cannot see any change?

     

    Correct I executed them then after rebooting I still did not see any change

     

    3. If the steps were executed successfully, but no change happened for Windows, then the linked article is where you should start. Are the steps in the linked article where you are running into an issue?

     

    I will look at this one again...I got a bit lost trying to sort through the first time

    1. Do you have any third-party NTFS drivers like Paragon, Tuxera or NTFS-3g/NTFSfree on the OSX side?

    2. If #1 is false, if you notice the gap between GPT#3 and #4 is where your correct NTFS header is sitting.

    3. Testdisk scans the disk sector-by-sector (when using Deeper Search) and finds such headers. It has the ability to look for files within such partitions.

    4. Once you locate a deleted NTFS partition that looks familiar, the current GPT#4 is modified (deleted/added with correct start/end disk sectors), the Hybrid MBR is recreated, and then tested to verify that Windows comes up.

    Notice the start/end/size of the Test Bootcamp line and compares it, first to the Fdisk entry #4 and then the gap between GPT#3 and GPT#4. This is indeed very helpful.

    The first image you posted, is excellent. The second image has what your current GPT looks like. Also notice the difference in size, 199114745 vs 119138304, this is where Yosemite corrupted your information.
