Why did my mobile restart automatically this morning?

[Windows Central Question]

Hi, all of sudden my lumia 630 dual sim started to restart automatically and while switching on displays error "unable to find boot options, press any button to shutdown".

Apparently, something terribly wrong happened to your software - this could either be a software-level problem or a hardware-level problem.

If it is a software-level issue, you can simply try to re-install the OS using the Lumia Software Recovery Tool, connecting your phone to your PC.

If this is a hardware-level issue, then the only solution is to take your phone to a service center and have them diagnose and repair the problem.

Should you wish to provide additional information or ask further questions, create a Windows Central account and then respond in this thread.
