Q: update to Capitan corrupted bootcamp

Loner, (continuing from Re: Bootcamp gone haywire after Yosemite update)

I'm facing the same problem when I updated to OS X EI Capitan. Below is my setting

 

prashanths-MacBook-Pro:meanHelloWorld pranag$ sudo gdisk /dev/disk0

Password:

Sorry, try again.

Password:

GPT fdisk (gdisk) version 1.0.1

 

Warning: Devices opened with shared lock will not have their

partition table automatically reloaded!

NOTE: Write test failed with error number 1. It will be impossible to save

changes to this disk's partition table!

You may need to deactivate System Integrity Protection to use this program. See

I ran the test Disk and it gives the below selections


Select a media (use Arrow keys, then press Enter):

Disk /dev/disk0 - 500 GB / 465 GiB (RO)

>Disk /dev/rdisk0 - 500 GB / 465 GiB (RO)

Disk /dev/rdisk1 - 148 GB / 138 GiB (RO)

 



I selected rdisk0


Below is what it shows


Write access for this media is not available.

TestDisk won't be able to modify it.

 

- No partition from this disk must be mounted:

Open the Disk Utility (In Finder -> Application -> Utility folder)

and press Unmount button for each volume from this disk

- This media may be physically write-protected, check the jumpers.

 

 

 

 

 

>[ Continue ] Continue even if write access isn't available

[ Quit     ] Return to disk selection



What do I do?
