laptop operating system crash

[PR13_56-]

Hello,

Yesterday my laptop crashed all of a sudden. It didn't start and showed error message -" Boot Device not found"

I did the 3-hour extensive test of the hard drive post which it started.

In my settings, it is showing that windows is not activated.

In my MS office also it is showing to activate the product before 28th August.

Please tell me what to do.
