Answer

Regarding mentioned errors most probably there is issue based on no enough memory assigned to virtual machine. To install Windows Server 2012 R2 you should have at least 800 MB of RAM specified in VM settings.

Check amount of assigned memory: Go to Settings of VM and choose Memory. If there is value lower that 800, change it to correct 800 MB or more. For this example 1024 MB are specified.

After that start installation process once again. In this case License Terms should be visible and possible to accept.

Any further actions should be done without any error. After the installation is completed you can go back to virtual machine setting and lower the Memory back to 512 MB. This is a minimum for Windows Server 2012 R2 version.
