Q: My Windows partition is not bootable after create a new partition

Hi all.

I'm using a Mac Air with El Captain 10.11.1

My bootcamp with Windows 10 was running ok, today i've created a new partition to extend windows partition.

It was made in Mac disk utiity.

 

After that windows is not bootable anymore.

Windows partition mount and work on Mac OS.

I have 3 partitions: Macintosh HD - Untitled - Windows.

 

Here are the output for some commands: (notice that windows partition is listed like disk 5)

 

diskutil list

diskutil cs list

sudo gpt -vv -r show /dev/disk0

sudo fdisk /dev/disk0

A:

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. If the 64G is converted to Free Space, these numbers (3 4 5) will change back to (2 3 4).

 

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.

 

Once SIP is disabled.

 

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

    1. What year is your MB Air?

    2. Please post the output of

     

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

     

    3. From Boot Camp: Resize the Windows partition,

        

    Warning: Do not use other apps or Windows to resize your partitions. If you do so, you could potentially damage your computer and prevent it from starting up.

    Your Fdisk output shows some partial records and the first entry show the entire disk in one entry used for a Protective MBR. Was another tool used or attempt made to correct Windows booting?

    Yes, i ran the tool in the windows dvd installation to try repair the boot

     

    Is it saying that the MBR is compressed?

    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.

    Thank you very much, you saved my day

    It works like a charm and my Windows is back.

     

    Now i need to merge the free space to my Windows partition, do you think that mini tool partition option is safe or is there a better option?

    1. If you are familiar with Linux Live CDs and GParted, you can use that, but it will void the MBR we created, because your GPT 4 will disappear. GPT4 must be converted to Free Space (it is currently JHFS+) and then merged.

    2. The second option is to use a Windows cloning tool like Winclone or CampTune and backup the current Windows, remove it, and restore it from backup to a partition of a larger size.

    Thank you again

     

    I think i understood. after merge two partitions i will get 4 parts (now i have 5) so the MBR will be wrong.

    It will work if i repeat that procedure changing numbers (decreasing by one)?

    1. Sudo gdisk /dev/rdisk0
    2. P  (Print list of parts)

    8. N  (part 2 boot flag)
    9. N  (part 3 boot flag)
    10. Y  (part 4 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

    Oh my God, i've made some serious mistake.

    I used GParted to try merge windows partition with the new created partition.

    It was a two step process: erase new partition (it was formatted by disk utility when created) and resize the windows partition.

    It returned an error and couldn't complete the task.

     

    After that my windows couldn't boot again with message "missing operating system".

     

    So i checked the disk lists in terminal and i have 6 partitions (plus free space) .

     

    I tried to execute the procedure above, but gdisk permit only list 3 partitions, so, the number 6 can't be listed.

     

    I'm so sorry that i've did this stupid thing.

     

    Mac OS is running ok - Windows doesn't show to boot, but it is mounted to access in Mac OS.

     

    It's possible to correct that? i'm considering format entire HD and install all things again.

     

    Some results:

    1. Use Gdisk and in the main menu, use the 't' command and change partition 3 from 0700 to AB00.

    2. GPT4 when converted to Free Space, will return an error, because there is valid disk - disk0s4 to start with, but Free Space cannot be mounted as a disk.

    3. How was GPT5 created?

    4. Run the DD command for disk0s6.

    Loner T, thank you very much again.

    It was restored for the previous state with windows HD returning the "missing operating system" error.

    Can i execute these steps again to make windows partition bootable again?

    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

     

    outputs now:
