Windows 10: Missing operating system

When I turn on my HP G60 notebook I am faced with a message saying "Missing Operating System", I know why it is happening, I accidentally deleted system reserved partition, I dont have installation media, I use windows 10

:)

 

After updates Windows 10 says "Missing operating system"

I have the same issue, and I followed your suggestion steps. After that, I can see C: drive, and Windows folder is there.

Then I rebooted the computer. But I still have the missing the operation system issue. Any suggestions?

Thanks.
