You can only have Legacy Network Adapters in Generation 1 VMs

Today I was trying to follow some instructions on how to boot a Hyper-V virtual machine from the network, and the steps said to add a Legacy Network Adapter to the machine, but the only similar thing I could find in the list of add-able things was a normal Network Adapter.

It turns out I was on a Generation 2 VM, and only Generation 1 VMs can have the legacy style of network adapter. Though it looks like a G2's network adapter will work fine - the problem I was having originally was with the network boot server, not necessarily my configuration. (I got to the PXE searching screen, and it found the server, but the downloaded boot file was zero bytes.)
