Hi
Need some urgent help here actually!
I am currently using osx el capitan and have a boot camp partition (windows 8.1). Tried to repartition it just now and it was successful but I tried to reboot up to windows but cant reboot?
Anyhelp??
Thanks!
This support thread is really good stuff.
I have followed the instructions on the first page and now my BootCamp Windows Partition is bootable again. I have recovered all my information without reinstalling Windows or macOS. It was just a boot issue.
Many thanks to all

Loner T I am lost i need your help open this link to my thread please ... Respect.
Please do not manipulate partitioning any further, otherwise you will lose data.
Can you post the output of the following Terminal commands?
diskutil list
diskutil cs list
sudo gpt -vv -r show /dev/disk0
sudo fdisk /dev/disk0
The "sudo" commands will prompt for your password, and it will not be echoed back. You may also see a warning about improper use of "sudo" and potential data loss due to "abuse" of the command.

Do you want to keep the 79Gb Untitled partition?
that was initially created to merge with the bootcamp partition though as there is not much space left in the boot camp partition.
Let us check the partition header for the Windows side. Please post the output of
sudo dd if=/dev/rdisk0s5 count=1 2>/dev/null | hexdump -C

A. We need to disable SIP.
1. Boot into Local Recovery (Command+R).
2. Start Utilities -> Terminal.
3. Type csrutil disable in Terminal and press Enter/Return.
4. Type csrutil status.
5. Boot normally, and type csrutil status to confirm that all individual entries are still disabled.
B. Rebuild non-standard MBR.
The following steps are non-standard because there is a third user-visible partition. Typically, there are two such partitions in a normal configuration on a single-disk Mac with OS X and Bootcamp. This is fragile and lack of proper backups can lead to potential data loss. Download GPT Fdisk from http://sourceforge.net/projects/gptfdisk/ and install it on the OS X side. The following steps are executed when booted in OS X. If the 79G is converted to Free Space, these numbers (3 4 5) will change back to (2 3 4).
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. Please see thesample Q&A as an example. These steps can be repeated if you make a mistake before you get to Step 12, otherwise start from Step 1 for these steps. Step 6 has numbers which are typed with a space between the numbers. Please see the sample Q&A before you execute these steps.
Here is sample Q&A for this section. Please notice the Press Enter/Return. Accept defaults offered by Gdisk.
Place EFI GPT (0xEE) partition first in MBR (good for GRUB)? (Y/N): Y
Creating entry for GPT partition #3 (MBR partition #2)
Enter an MBR hex code (default AF or AB): Press Enter/Return
Set the bootable flag? (Y/N): N
Creating entry for GPT partition #4 (MBR partition #3)
Enter an MBR hex code (default AB or 0B or 0C): Press Enter/Return
Set the bootable flag? (Y/N): N
Creating entry for GPT partition #5 (MBR partition #4)
Enter an MBR hex code (default 07): Press Enter/Return
Set the bootable flag? (Y/N): Y
so i just have to follow these and the problem would be solved? and after this i can proceed with my resizing of bootcamp partition?
