I just wanted to load into my laptop while I opened it there was no bootable device and now I do not know what to do anymore?

Is no bootable device what bad would that break my laptop?

This means that no boot medium is available. Go into the BIOS and see if the right hard drive is selected as boot medium. If your system hard drive is not there's something wrong with the hard drive or you have never set up the PC, which of course could be synonymous ne possibility. Then you would first have to create a boot stick or something and load an OS on the laptop.

I do not know myself with laptop

Jap, I would have come on it myself.

Google times, to the terms I've used relatively quickly what and there are good detailed instructions on the Internet.

So on the topic…

Who the hell is "General Failure" and what did he lose on my hard drive?

Dear questioner, you should work through and answer the answers bit by bit, then someone can help you. But it would be better, if somebody in your area looks at your laptop, that would help you…

Either the operating system (presumably Windows) damaged or the hard drive is defective or the hard drive has come off the port of the notebook.
