PXE Boot in Hyper-V Gen1

[Matschek]

I cannot complete a boot attempt on a Hyper-V Gen1 machine with legacy network adapter installed. I tried several of the logo resolutions as well as chosing CLI.

   
   

VM with Gen2/EFI works great.

Currently I have no idea about this.
May be you can try different settings about the graphic/monitor setting for the VM.
