bootcamp partition not showing up in El Capitan

I just upgraded to OS X El Capitan, however, my windows partition is not showing up either in disk utility or start up menu. I see that my mac partition is still the same size as i left it (500 GB) while its missing the windows partition (250 GB). I followed this

sudo fdisk -e /dev/disk0

p

setpid 4

07

flag 4

p

write

y

but i get an error when i use the command "write" it says "operation not permitted"


I have a macbook pro mid 2012 with 750 GB HDD

Please help!!!

MacBook Pro, OS X El Capitan (10.11)

Please post the output of the following Terminal commands


diskutil list

diskutil cs list

sudo gpt -vv -r show /dev/disk0


You may run into more issues, because some of the tools do not work on ELC yet.
