It looks like your computer is attempting a PXE boot, which means it's searching your home network for a server image to boot from. The error is because no such network server exists.
Configure your computer to boot to Windows instead. Turn on your computer again, but this time, press ESC and then F9. If you see your Windows installation on the list of boot options, select it to boot to Windows.
If you don't see your Windows installation on the list, you may have to reinstall Windows. Ifixit has a guide for installing Windows 10 below:
