    1. diskutil list

    CCs-MacBook-Pro:~ CheungChing1$ diskutil list

    /dev/disk0

       #:                       TYPE NAME                    SIZE       IDENTIFIER

       0:      GUID_partition_scheme                        *251.0 GB   disk0

       1:                        EFI EFI                     209.7 MB   disk0s1

       2:                  Apple_HFS Macintosh HD            175.0 GB   disk0s2

       3:                 Apple_Boot Recovery HD             650.0 MB   disk0s3

       4:       Microsoft Basic Data                         55.1 GB    disk0s4

     

     

    2. diskutil cs list

    CCs-MacBook-Pro:~ CheungChing1$ diskutil cs list

    No CoreStorage logical volume groups found

     

    3. sudo gpt -vv -r show /dev/BootcampDiskWithoutSlice (where BootcampDiskWithoutSlice is of the form disk0 and is visible from the output of 1.)

    CCs-MacBook-Pro:~ CheungChing1$ sudo gpt -vv -r show /dev/BootcampDiskWithoutSlice

    Password:

    gpt show: unable to open device '/dev/BootcampDiskWithoutSlice': No such file or directory

    CCs-MacBook-Pro:~ CheungChing1$

     

    4. sudo fdisk /dev/BootcampDiskWithoutSlice

    CCs-MacBook-Pro:~ CheungChing1$ sudo fdisk /dev/BootcampDiskWithoutSlice

    fdisk: /dev/BootcampDiskWithoutSlice: No such file or directory

     

    5. sudo dd if=/dev/rBootcampDisk count=1 2>/dev/null | hexdump -C (where BootcampDisk is of the formdisk0s4 and is visible from the output of 1. Please note the 'r' preceding the disk0s4 format).

    CCs-MacBook-Pro:~ CheungChing1$ sudo dd if=/dev/rBootcampDisk count=1 2>/dev/null | hexdump -C

    In commands 3 and 4, replace BootcampDiskWithoutSlice with disk0.

     

    In command 5, replace rBootCampDisk with rdisk0s4.

     

    Did you delete any partitions after you changed Bootcamp by 20GB and it stopped working?

    Hi Loner T,

     

    sorry for the late reply.. Coz i ma living in the uk..

    As followed the instructions, Command 3 and 5 still the same. And I've tried to replace the "rBootcampDisk with rdisk0s4 count=1 2>" to "rBootCampDisk with

    rdisk0s4". but it appeared unknown operand.

    Here was i have done yesterday,

    I have OS X and Win7

    OS X was 195 GB and Win7 was 55GB, I made 20GB from OS X's partition to unallocated spaces, and back to Win7, used a software to expand the 20GD into the bootcamp. it was fine when i have done it. after a couple of hours, i back home, and i was formatting one of my external hard-disk to exFAT (however, the external hard-disk cannot be recognised in mac if i format it in Windows, or the other way round.)

    anyway. it just HAPPENED after i formatted the external hard-disk..........

    that's the whole story....

    Screen Shot 2014-10-02 at 12.50.18 am.png

    and i found out that, the 20GB did expanded in Bootcamp, but back to OS X, the 20GB appears in grey, and shown that the Bootcamp is still 55GB.

     

    many many thanks!!!!

    I cannot see the images. Can you post text versions the way you posted the output of diskutil list?

     

    From Boot Camp 5.1: Frequently asked questions

     

    How can a Windows partition be resized after Windows is installed?

    You need to delete the Windows partition using the Boot Camp Assistant, and start over to change the size of the Windows partition. Back up your important Windows files first.

    Unless you want to make a significant effort, there is no easy way to recover lost space. The NTFS header begin intact is a very good sign.

     

    The following steps fill make the current Windows installation bootable. (Please ignore the i386/boot0 error message in the following steps).

     

    sudo fdisk -e /dev/disk0

    setpid 4

    07

    flag 4

    p

    w

    y

     

    Reboot.

     

    1. Test 1 - Bootcamp volume shows up in Finder.

    2. Test 2 - Bootcamp volume files are visible in Finder.

    3. Test 3 - Bootcamp can be selected in System Preferences -> Startup Disk.

    4. If Test 3 is successful, select Restart.

     

    If you get a black screen with a hanging underline cursor in the top left corner, please be patient and give it a few minutes and check if Windows will come up.

     

    If that does not work, you need Windows Startup Repair using your Windows Installation Media.
