Boot Camp Partition Won't Launch After HD Resize in OS X 10.9.5

Hi,

I resized my OS X partition and now my Boot Camp instance won't launch. I'm hoping @Loner T can help me with this.

1. This Gap between GPT2 and GPT3 is where a 'lost' NTFS partition should exist. Can you use Boot Camp missing after upgrade as a reference, and download Testdisk and GPT Fdisk and start a partition search using Testdisk?

2. This is not the typical MBR. Also you are missing Recovery HD, but it does not impact the Windows/OSX. Command+R will start Internet Recovery instead of Local Recovery.

I'm not deleting part 4 (step number 4) so which part 1-3 should I delete? It's pretty obvious, but I want to be absolutely sure.

You will need to delete part 3 (Bootcamp), and recreate it. As an aside, GPT2 has a strange name.

Just noticed your sample...

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

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

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

So.... Ran my test and here are the results...

Test 1 - Does Bootcamp Volume show up in Finder? YES

Test 2 - Can you see files in Bootcamp Volume? NO

Test 3 - Can you select Bootcamp in System Preferences -> Startup Disk? NO

Test 4 - If Test 3 is successful, select Bootcamp and Click Restart. TEST 3 FAILED SO I DID NOT PROCEED TO TEST 4....

Thanks!
