Laptop gives stupid comments and does not start anymore?

The laptop of my wife (about 4 years old, from ALDI) does not boot anymore, he is lame and quite stupid (MEDION / intel) with the medieval DOS and says: "For Atheros PCIE Ethernet Controller v. 2.0.1.2 (07 / 29/09), then: check cable connection! And then: PXE-M0F: Exiting Intel PXE ROM and then: Reboot and Select proper boot device

So I need a working boot-stick! How do you create that?

After that I would like to delete everything on the laptop and reinstall Windows 10.

I have a "big" PC with Windows 10 (MEDION, also from ALDI), which runs very well and from which I'm currently working. Corresponding. I have already downloaded the file: Windows.iso.

Is there no hard disk in there?

Of course, the thing has worked well for years

What is registered as the 1st boot device in the BIOS?

Sata CD: P4: TSSTcorp CDDVDW SN-S083F

No hard disk? Is she even recognized?

Of course, this is a hard drive in it, no idea if it is no longer recognized.

This setup utility is ancient lavender

Then just enter the HD as the first device, whether it starts.
