Repairing Boot Camp after creating new partition

I'm running OS X 10.9 and Windows 7 x64 Pro.

I set up Boot Camp to dual-boot Windows on my MacBook Pro Retina. Everything was fine. And just yesterday Apple released the Yosemite Beta for the public and I wanted to download this and give it a try. After some research, I found that creating a separate partition was the way to go, and so I made another partition.

I wasn't aware that this would affect my Windows partition as I thought it was completely different.

So now, when I boot up, there is no option to boot with Windows. But when I boot the Mac and select Startup Disk, it shows Boot Camp is still there and all my files etc are still there.

I have a 256SSD, 160GB was for the Mac, and I have 90GB set for Windows.

I made the new partition to 40GB (and the Mac was now 120GB).

Then once I completed that part, I restarted my Mac and the Windows boot option was no longer there.

I didn't even install the Yosemite yet. I went to Disk Utility and deleted the 40GB partition that I made.

Now I don't know what to do. I have a lot of important things which are still on my Windows. Is there a way to restore normal Boot Camp functionality?

MacBook Pro (Retina, 13-inch, Late 2013), OS X Mavericks (10.9.4)

This is Internet Recovery, because your internal Local Recovery is corrupted or you used Command+Opt+R during boot up.

Please also see About OS X Recovery - Apple Support .

Your internal Recovery HD is corrupt. What are you trying to recover? Please start a new discussion and post details of your problem.

Can post a new discussion and post the output of the diskutil and sudo commands? It will help confirm the issue. You will also need to disable SIP, if you have El Capitan or higher OS X version.
