Windows 10: Updating windows to 1703, gives error 'missing operating system'

Recently I was trying to update my windows to 1703 (Windows feature update). When the update is in progress, machine restarted with error mentioning 'missing operating system'. I tried to repair windows with bootable usb drive. In Diskpart I got to know that C drive (windows is installed in this drive) format was changed to raw from ntfs. I tried rebuilding bcd. Nothing fixed. At that point I dont know that the issue was with the feature update 1703.

Finally what I did is, I formatted the whole C drive and installed windows 10. Again I tried updating to the feature update 1703. Now again the same issue 'missing operating system'. I don't know the reason. How to update my machine to upcoming windows updates?

Thanks in Advance!!

Hi Bryan,

The missing operating system error that you are getting can occur due to several reasons such as, a system hard disk drive failure, a corrupted master boot record, etc. We recommend that you repair your operating system using the Media Creation Tool by following

Hi, hope you had disk images (e.g. via Macrium Reflect (free).

- This suggests you installed 1607 (the Anniversary edition) then upgraded.
If so, why not simply download the 1703 iso and use that?

I would also suggest it's worth you checking your disk - e.g. Hard Disk Sentinel (trial).

 

Thank you dalchina!

Unfortunately I don't have disk images. All my data in C drive are gone.*cry*cry

Yeah as you said my next step is to install 1703 iso. But my doubt is, why I couldn't update directly?. Any issue with my hard disk?
