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.

Loner T. ,

I have one doubt, in the case I have a 5th partition, (Code: 2700, "windows recovery environment partition"), I should proceed the same as partitions 2 & 3? Or I should set a "boot flag" or just delete?

I have not resized, just made a new Windows 8 instalation using BootCamp suggested procedure. I was able to start Windows, update, etc. However after "going back to Mac OS, no option to select bootcamp as "startup disk". The machine is a MacBook Pro 13" I purchased last month. (below will find partition data)


Thanks in advance

I don´t understand why I need to do a Windows recovery, I upgraded from W8.0 to W8.1 then to W10, the installed bootcamp drivers and restarted several times my W partition, it was just after (using bootcamp) I decided to boot again Mac Os, when I am no longer able to get an option to boot from Windows again (start up disk selection only shows mac os).
