I really need help! Bootcamp Partition GONE! Loner T please Help!

Hello. I Have been using Windows 7 with Bootcamp on my Macbook Pro Late 2013 15 inch Retina 16GB 2.6GHz Core i7 since I bought the computer brand new. I turned on my mac the other day and out of nowhere, the Windows Partition was gone. The only thing that I did do differently was that I turned on FileVault and encrypted my system. I am wondering if it affected my partition because of that? I am not sure. I am nervous, though because I have all of my really important work files on the partition and I haven't been able to access them at all.



Everything I tried to do so far:


I tried plugging my MBP into my iMac and booting it in target disk mode and I couldn't find any files from the Windows partition. For some odd reason the bootcamp partition is greyed out in Disk Utilities and it is now called "disk0s4."


I have a Windows 7 disk that I was able to boot from and it was about to install Windows but I was afraid that it was going to overwrite everything so I canceled it.


When I boot my MBP now and hold alt, like I used to always have to do to get into Windows, it shows 2 "Macintosh HDs" whereas it used to show one "Macintosh HD" one "Recovery Drive" and one "Windows" drive. (I am guessing that by encrypting the drive it may have messed up the naming of the voumes... Not sure)


I have turned off FileVault, unlocked, and decrypted the system to see if it would help but no luck.


I tried hitting verify disk and then repair disk and nothing worked.


I also tried to hit mount disk and that did nothing.


Is there any way I can access the files on the partition if there is no possible way to install windows 7 again without overwriting everything?



To anyone who helps answer this, thank you in advance. I am so stuck!!!



I have been reading the forums and I saw that "Loner T" asked someone to type in these commands in terminal:


diskutil list

diskutil cs list

sudo gpt -vv -r show /dev/disk0

sudo fdisk /dev/disk0


Check my terminal results below: I also attached the text file of the terminal session.

What do I do? I didn't know what option to choose at the end? I have to choose b-x right? I followed the exact steps as you wrote to the other post, but my setup is a little different than hers so maybe I did it incorrectly? I am afraid to exit the terminal at this point. I will just wait to see what you say to do.


I tried to type in exit and this is what it said:


This will probably do weird things if you've converted an MBR to

GPT form and haven't yet saved the GPT! Proceed? (Y/N): n


Then I put in: n

Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING

PARTITIONS!!


Do you want to proceed? (Y/N): Y

OK; writing new GUID partition table (GPT) to /dev/rdisk0.

Warning: Devices opened with shared lock will not have their

partition table automatically reloaded!

Warning: The kernel may continue to use old or deleted partitions.

You should reboot or remove the drive.

The operation has completed successfully.

Please back up Windows using Winclone to an external disk and create a Windows System Restore point.
