BOOTCAMP Partition lost after some updates in Yosemite

Hello Everyone,

I have a Mac Mini, bought in Dec 2013 and have been using Windows 8.1 since more than a year now. I did update it to OS Yosemite whenever it was available. But just 2 weeks back, I thought that its been many months now since I rebooted into Mac and there might be lots of updates pending. So I did that but right after the updates completed, when the Mac rebooted itself to finish installing the updates, the Bootcamp partition was gone.😟 When I forcefully shut it down and rebooted back into Mac, the Bootcamp was not there in both, StartUp Disk Manager and Disk Utility. 😟

Please Help Me. I have loads of important data on Bootcamp which I cannot afford to lose. Please save me from going into a state of depression if I lose that data.

On searching other threads I found that I have to post the output of the following commands from Terminal. So here's all the ground work done.

Please see below and help.

Additionally, I thought even these might be helpful to analyze.
