Bootcamp install not working after update

I have a 2015 MacbookPro 15inc with Windows 8.1 installed under bootcamp. I had an update mess up bootcamp earlier in the year, but was able to fix it using command prompt. However since updating 2 days ago bootcamp has stopped again and anything I do does not work.


When I boot with option key I see a mac and windows option, when I follow the windows I get an immediate blue screen with error 0xc00000e. I have tried various diskpart and bcd commands with no success, in-fact now I have two options for windows on boot, neither of which work.


I have looked at some of the other inputs in the forum and have posted the requested info from command below:

On a GPT disk,


1. EFI is required.

2. CS is Yosemite default.

3. Local Recovery HD.

4. For UEFI mode, MSR and MSD are required. There is an excellent explanation from Microsoft at https://technet.microsoft.com/en-us/library/dd799232(v=ws.10).aspx

5. The last one is a Windows Recovery Environment (RE) similar to Mac's Recovery HD. The link in bullet 4 contains an explanation of Windows RE.
