Q: Bootcamp not showing in finder

I recently reduced the size of my Mac HD on my Early 2013 Macbook Pro Retina and then booted to boot camp and reallocated the space to the bootcamp partition.

 

I just noticed that bootcamp is missing from the finder and from Disk Utility. I can still boot to bootcamp like normal though. In disk utility it's now called disk0s4.

 

Is there an easy fix for this?

 

I'm running 10.9.5

MacBook Pro (Retina, 15-inch, Early 2013), OS X Mountain Lion (10.8.5)

    You have the same issue as many others. Can you use Yosemite Upgrade Broke Bootcamp as an example and get Testdisk started?

    Yes - I have read a few similar threads. However, my problem is limited to bootcamp missing in Finder. It hasn't effected the startup options - I can still boot into bootcamp. I have yet to find a thread with this situation.

     

    I am thinking that I could boot into windows, do a back up, and then create bootcamp from scratch. Hoping there is a quicker solution though.

    Can you post your MBR, it may mismatch the GPT?

     

    Your issue is the following gap.

     

    353662976   19384320      4 

    373047296  117186560      4  GPT part - EBD0A0A2-B9E5-4433-87C0-68B6B72699C7

    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.

    Thanks. Can you tell me how to post my MBR?

    Please post the output of sudo fdisk /dev/disk0 which is your MBR.

    I got permission denied, so I put in "sudo " before the command and it worked.

    Your problem is very interesting...

     

    Your GPT shows

     

    353662976   19384320      4 

      373047296  117186560      4  GPT part - EBD0A0A2-B9E5-4433-87C0-68B6B72699C7

     

    while your MBR shows

     

    *4: 07 1023 254  63 - 1023 254  63 [ 353662976 -  136570880] HPFS/QNX/AUX

     

    Your MBR is correct, so you can boot, but your GPT entry is incorrect, so you cannot see it in Finder.

     

    To correct your GPT entry...

     

    Use the following...

     

    1. Delete the old entry and create a new entry at GPT#4.

     

    sudo gdisk /dev/disk0

    p

    d

    4

    n

    4

    353662976

    490233855

    0700

    p

    w

    y

     

    2. You will need to reboot after the change, because the disk you are booted from is the one being modified. Reboot will rebuild disk0s4 using the start/end you entered.

     

    3. Run the dd command - sudo dd if=/dev/rdisk0s4 count=1 2>/dev/null | hexdump -C and check that the first line contains "R.NTFS".

     

    4. Verify read-only access via Finder.
