Bootcamp gone after partitioning

I've looked throughRe: Repairing Boot Camp after creating new partition and can't seem to yield anything when following many of the steps given. I have very little experience with Mac so perhaps I didn't follow some steps properly.

I have a Macbook Pro running 10.9.5 OS. I partitioned my drive using the Mac tool within OS and a Windows tool which I can't remember the name of on the MS side. I didn't notice any issues until I left Windows for OS and tried rebooting into Windows again. The Bootcamp option was gone:

At this point I'd be happy just to get the data off the Windows side and will buy a dedicated work computer once complete. If someone could offer some guidance it would be appreciated

Here the result of the basic commands. Thanks in advance.

You can download W7 Installer from Microsoft - https://www.microsoft.com/en-us/software-download/home. if your Mac support creating a USB Installer, use BCA to create a USB Installer, otherwise burn the downloaded ISO to a physical DVD, and boot from the Windows Installer and repair your W7 installation.

Okay. I'm a little reluctant to do more now as I've got my data back (my initial goal) and I'm about to leave on a trip that I'll need my computer for. Don't want any issues while on the road. I'll perform the above steps when I get back.

Thank you again for your support, I was sure my machine was gone at one point.

If ever in Seattle let me know and I'll get your dinner and beer.

Hi Loner T,

May I chime in here in this thread or do you want me to start a new thread? After trying to install Windows 10 on a septerate SSD, my EFI Windows 8.1 x64 SSD would boot anymore. Now I even get two start-up disks 1. Windows & 2. EFI Boot, for the Windows boot disk when using the option key:

I need help to fix this. Thanks in advance and directions appreciated!

Cheers

I ran out of room on my bootcamp disk. Found a youtube video on how to change bootcamp partition size using mac disk utility, I believe he was running Mavericks. I am however running OS X 10.11, El Capitan and the interface has changed. I couldn't find any forums on how to do this on El Capitan, so I messed around with Disk Utility trying to change the partition size. When I found that I could not modify the size of BOOTCAMP within disk utility, I deleted the additional partition that I had made in error. When I rebooted my computer holding alt, the BOOTCAMP option was gone.

I originally found this thread: Repairing Boot Camp after creating new partition and was redirected here.
Is there a way to get my bootcamp option back at boot? Would really appreciate the help!

Not very familiar with terminal but I am willing to go as far as needed, I need access to my bootcamp as soon as humanly possible.

Also, when I set the startup disk to BOOTCAMP, I get the "no bootable disk" line.

Thanks!
