MacOS Internet Recovery Error 2100F

Hello,

I have a problem about MacOS reinstallation / Internet recovery error 2100F !!

Yesterday, I formated my MacBook Pro hard drive (now it is completelly empty, it apears a "?" ) and then I ran Internet Recovery...At first, it seemed to be okay but while MacOS installation was running, this message was appeared: {Installation could'n be completed} and installation was interrupted. So I restarted the machine!

After restarting,in any recovery method...{Cmd + R or Cmd + Option + R or Cmd + Shift + Option + R}

...system appeared me an error code message { apple.com/support -2100F } ...

...I changed SSID, I connected it with LAN cable directlly on the router(100Mbps) in order to fix it but it did'n work!

Unfortunately, I don't have a MacOS installation disk or an installation USB !! I don't have an other Mac in order to make installer or anything else...I have only one Windows 10 machine!

I would be very pleased if you helped me!!

Thank you!
