Someone who knows about laptop?

Just turn on my laptop and then came directly this text…

When I press a key, the text just comes back.

Can someone help me?

Look whether the SATA or the power cord from the hard drive is the best you go again in the bios and look what is under the category Boot Devices

For laptops, this is usually not a cable, but a fixed slot with normally on the board firmly moniteireter SATA interface (power and data)

Which operating system is installed? Seems to have a problem with the boot drive.

The hard drive was no longer correct in the interface. Works again:-)

The hard drive was no longer correct in the interface.

Now everything is back.

Your BIOS / UEFI can't find any operating system that can start it. I assume your file system is corrupt.

Because of your question, I assume you use Windows? Do you still have the installation media? If so, connect it to the laptop / insert the CD in the drive and then boot from said disk. This should do your laptop automatically, if I'm correct with my assumption.

There should also be a point in the Windows installation menu that says "fix" or something like that. The select and see if the problem is fixed after the repair.

Should not be the case… Perhaps the SATA cable has been removed from the hard drive? Unfortunately, we can only speculate here what it is.
