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)

Hey mate, I posted on here and a guy called loner t or something replied and he really wasn't helpful ay all in fact he went on to ignore my post.

I found it easier booting into mac and using the bootcamp assistant to re install and really partition windows because no one wants to help!

It is hard to keep track of individual requests, if individuals post on a solved thread. In your case, the post fell off during the New Year 'busy' window. Apologies. It seem you have already worked around the issue. 😎
