Laptop shows this message after start?

My laptop shows these messages after I start my computer how can I fix it, is it because the HDD is flat and I have to put windows on it again?

? What did you do before Possibly. Do you have a USB hard drive or stick connected?

He can't find anything to boot from. If you already know that your mass storage does not contain a system: Yes, it is probably because of it.

Is it because the HDD is flat

YES!
The error message says that your computer can't find an operating system to start.

There can be several reasons:

No operating system is installed yet.
The motherboard does not recognize the disk correctly.
The plate is broken.

If the disk is new, probably only the operating system is missing.

There's no boot sector on the disk. Either the whole plate is defective or none at all.
