I do understand that this is a common problem, and I have read few of the threads. Here is synopsis of my problem. 

Logged on to window 8.1, windows installed updates and now grub2 doesn't work

* Laptop is a Toshiba C55-A
* Secure boot is disable
* Turn off fast startup
* booted with Ubuntu 12.04 LTS Live CD
* by pressing c accessed grub prompt
* exited out of grub at which point was able to access boot manager
with Windows Boot Manager, Ubuntu, Ubuntu options
* Selected Ubuntu
* Booted into Ubuntu
* sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update
* sudo apt-get install -y boot-repair && (boot-repair &)
* Selected recommended repair

The output on boot tab from msconfig (windows command prompt) shows only windows 8.1

The output from the bcdedit is as follows 

```

```

Did not see the grub2 menu as expected?

Any other ideas
