@Loner T — seems you have helped several others on this issue and hope you can help me through it too. I have an early 2013 MBP with a 500 GB SSD. I allowed the upgrade to El Capitan and like others this made the boot camp partition disappear. Holding the option key when booting only displays the option to boot into OS X. Here’s what I’ve done so far:
– SIP is disabled. Confirmed after rebooting normally by typing csrutil status
– Tried to make the other partition bootable by using your instructions on
— fdisk -e /dev/disk0
— p
— setpid 4
— 07
— flag 4
— p
— w
— y
After quitting, I rebooted and hit option. Windows now appears when I hold option down, but when selecting it I get the error “Operating System Missing”
Here’s the output from all of the other commands:
diskutil list gives:
/dev/disk0 (internal, physical):

diskutil cs list displays
gpt -vv -r show /dev/disk0 displays:
sudo fdisk /dev/disk0 gives:
I figure all this means I have a lost partition as you have described to others. I downloaded Testdisk and gdisk. Testdisk output:
Running a Quick Scan on Test disk and see these unrecoverable partitions (dumb question does that mean these are lost for good or that they are good and don’t need to be recovered?):
Then Continuing:
Selecting P here produces:
Are these the values I can use in steps 7 and 8 in this post?
