To prepare a Windows Server 2012 for a Lync 2013 installation, install the following features manually before you run the Lync setup:

.Net Framework 3.5

Windows Identity Foundation 3.5
Media Foundation
HTTP Activation

Use the Powershell to speed up the installation:

Install-WindowsFeature –name NET-Framework-Core –source D:\sources\sxs (the Windows 2012 Disk is mounted on D: )

Install-WindowsFeature –name Windows-Identity-Foundation,Server-Media-Foundation,NET-HTTP-Activation

If you have to prepare the AD schema, install also the AD DS Administration Tools.
