Q: Win 7 won't boot after creating new partition for fileswaping.

Hello there!

 

As the header says, Windows 7 won't boot. Made a partition to swap files between OS X and Win 7.

I saw in a thread that it could be fixed using fdisk. I'm really new to OS X, so I really dont

know what to do. Just writing the outcome from the commands I found in the thread.


I now know there is a warning about making partitions AFTER installing Windows.

 

Would really appreciate if anybody took some time telling me what to do!

    Please post the output of

     

    sudo dd if=/dev/rdisk0s5 count=1 2>/dev/null | hexdump -C

     

    Can you see Windows files in the Bootcamp volume using Finder?

    El Capitan requires disabling SIP to manipulate partitions. This will not work if you boot into Internet Recovery (Command+Opt+R), but only works in Local Recovery (Command+R).

     

    1. Boot into Local Recovery (Command+R).

    2. Start Utilities -> Terminal.

    3. Type csrutil disable in Terminal and press Enter/Return.

    4. Type csrutil status.

    5. Boot normally, and type csrutil status to confirm that all individual entries are still disabled.

     

    The following steps are non-standard because there is a third user-visible partition. Typically, there are two such partitions in a normal configuration on a single-disk Mac with OS X and Bootcamp. This is fragile and lack of proper backups can lead to potential data loss. Download GPT Fdisk from http://sourceforge.net/projects/gptfdisk/ and install it on the OS X side. The following steps are executed when booted in OS X.

     

    Rebuild MBR to match the new GPT information thus resetting the Hybrid MBR. Use defaults for other questions (like partition codes). The only values that need modifications are the Boot flags and step 10. Accept all other defaults that Gdisk offers. Please see the sample Q&A as an example. These steps can be repeated if you make a mistake before you get to Step 12, otherwise start from Step 1 for these steps. Step 6 has numbers which are typed with a space between the numbers. Please see the sample Q&A before you execute these steps.

    1. Sudo gdisk /dev/rdisk0
    2. P  (Print list of parts)
    3. R  (Recover)
    4. O (print current Hybrid MBR)
    5. H (chooses Hybrid)
    6. Partitions numbers to be hybridized: 3 4 5
    7. Y  (Good for GRUB question)
    8. N  (part 3 boot flag)
    9. N  (part 4 boot flag)
    10. Y  (part 5 boot flag make NTFS bootable partition)
    11. O  (print current Hybrid MBR)
    12. W (Write the new MBR)
    13. Y (Yes! write the new MBR)
    14. Reboot

     

    Here is sample Q&A for this section. Please notice the Press Enter/Return. Accept defaults offered by Gdisk.

     

    Place EFI GPT (0xEE) partition first in MBR (good for GRUB)? (Y/N): Y

     

    Creating entry for GPT partition #3 (MBR partition #2)

    Enter an MBR hex code (default AF or AB): Press Enter/Return

    Set the bootable flag? (Y/N): N

     

    Creating entry for GPT partition #4 (MBR partition #3)

    Enter an MBR hex code (default AB or 0B or 0C): Press Enter/Return

    Set the bootable flag? (Y/N): N

     

    Creating entry for GPT partition #5 (MBR partition #4)

    Enter an MBR hex code (default 07): Press Enter/Return

    Set the bootable flag? (Y/N): Y

    Please create a regular backup schedule for OS X, FILDELING and Windows, and create a Windows System Restore point.

    Time Machine for the whole system, and then Windows System Restore point?

    1. Time Machine for OS X and FILDELING.

    2. Windows Backup for the Windows partition on a separate disk.

    3. Windows System Restore point.

    I see that you are pointing out that I should use a separate disk for Windows backup.

     

    But can't I just take the Win backup on a separate partition on my "WD My Passport"?

    And of course Time Machine backup on one of the partitions as well.

    Yes, you can use the WD, as long as you keep the partitions separate. The WD is now a single-point-of-backup-failure. 


    Is the WD a NAS or a direct-attached disk? Be aware of Backup disks you can use with Time Machine - Apple Support . Non-Time Capsule disks cannot be network-attached for Time Machine backups.
