BOOTCAMP partition not showing up on Mac OSX after resize

Using the Imgur screen and the first MS Data after the Recovery HD, the most likely candidate is

The last entry shows a list of partitions that cannot be recovered. Press Return to Continue.

Here is a table using that screen.

Can you scroll down to this and use 'P' to list files and post a screen shot or IMGUR link?

Leave your Testdisk display and start a new Terminal Window. You need to use the following steps. You will need to installGPT Fdisk (aka Gdisk).

If you see any error messages during the following steps, please stop and post back here with the error message. The following steps have values from your Testdisk output (and you can verify) in Steps 7 and 8. Notice the '+' sign in step 8.

Rebuild GPT4 using start/end offsets

1. Sudo gdisk /dev/rdisk0
2. P (print the full list of parts)
3. D (delete)
4. 4 (part 4)
5. N (new part)
6. 4 (part 4)
7. 1076582400 - Start offset in bytes (start point for Bootcamp part)
8. +876941305 - Size offset (as opposed to End offset)
9. 0700 (Windows part type)
10. P (print list of all parts just to see what changes will be made)
11. W (Write the new GPT)
12. Y (Yes! really write the new GPT)

This will delete and re-write the GPT partition info for /dev/disk0s4.

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.

1. Sudo gdisk /dev/disk0
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: 2 3 4
7. Y (Good for GRUB question)
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

Here is sample Q&A for this section. Please notice the Press Enter/Return.

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

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

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

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

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

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

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

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

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

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

Test 1 - Does Bootcamp Volume show up in Finder?

Test 2 - Can you see files in Bootcamp Volume?

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

Test 4 - If Test 3 is successful, select Bootcamp and Click Restart.

You can boot into Windows. The partition requires Windows Startup Repair.

Hello Loner T.

I have the same issue with my bootcamp partition and was trying to follow the steps you have suggested. How did you work out which partition is the bootcamp partition and which partitions to hybridize?

Please start a new discussion and post the details of your current status. I can provide explanation to look for the correct partition.

I have created a new discussion here. Many thanks.
