Help me with laproppronl?

My laptop doesn't start up, problems come up, I tried to solve problems with YouTube video, now I always end up there.

Can anyone help me?

You don't see a hard drive in the BIOS, that means your laptop won't find a storage medium where Windows is on it! So it may well be that the hard drive is broken or it is simply not recognized! You can look at Sataconfiguration if it says AHCI to rule out an error, otherwise you might see if the hard drive is still properly connected in the laptop!
