Repairing Boot Camp after creating new partition

If you are on El Capitan or Sierra (or later), you need to disable System Integrity Protection temporarily. See Re: bootcamp fails to start after upgrade to macOS Sierra as an example.

Can I ask the hosts to change the title to be something different than the original thread you came from to avoid confusion?

Typically, BC support 4 partitions, EFI, OSX, Recovery HD and Bootcamp. You have GPT#5 and GPT#6. This is inherently fragile and software updates can cause problems.

The NTFS header looks good. If you want to keep it this way, I suggest using Gdisk to create a new Hybrid MBR with 5 and 6, which will put 1,2,3,4 into a single MBR entry. It can break, so you may have to repeat this process.

Do you need steps for the Hybrid MBR?

You will need to remove partitions 5 and 6, and recreate the MBR, because your MBR output in the first screen shot shows a single protective entry for the whole disk. You are going to need Gdisk. How were these partitions created? Disk Utility? Your http://imgur.com/jYfcs74 image shows Multimedia and NTFS which need to be deleted, and tis http://imgur.com/yQ1q38W needs to be rechecked.

If it looks clean, then a new Hybrid MBR via GDisk is needed.

1. The dd command now becomes (after partitions were deleted) as sudo dd if=/dev/rdisk0s4 count=1 2>/dev/null | hexdump -C.

2. The MBR needs to be updated to be 07 and flagged via fdisk.

3. The literal "<DiskWhereYouHaveInstalledBootcamp>" is disk0s4 or rdisk0s4 as appropriate.

Yes the dd via OSX Terminal and then

sudo fdisk -e /dev/disk0

setpid 4

07

flag 4

Congratulations.

I suggest looking at these two resources.

There is a general Unix Shell book O'Reilly series - http://www.amazon.com/Learning-bash-Shell-2nd-Edition/dp/1565923472/ref=sr_1_3?i e=UTF8&qid=1414181024&sr=8-3&keywords=o%27reilly+bash

This is also an excellent resource - https://developer.apple.com/library/mac/documentation/OpenSource/Conceptual/Shel lScripting/Introduction/Introduction.htm…

I have a similar issue based on the original thread that this was from. I have tried running these commands and I do not get a working resolution. Are there any other commands that might fix the partition? I can not use bootcamp or remove the partition that created when bootcamp crashed. I posted a question in the iMac community, but I think this would be a better place to ask since I did not get much response other than 1 person who said your hosed, start over.

Here is the base command and results that I ran. Not sure if that is enough to suggest where to go next.

Thanks

sudo gpt -r -vv show disk 0

I got the following response.
