virtualbox – 无法安装DHCP服务器,磁盘空间不足

尽管有超过3GB的可用空间,但我无法安装DHCP服务器角色.

这最初是一个10GB的虚拟盒驱动器映像,但是当我遇到空间问题时,将驱动器扩展到12gb.我随后运行chkdsk和defrag,看看我是否可以让Windows识别可用空间.

有什么方法可以说服Windows Server 2012我有足够的磁盘空间吗？

来自TechNet the absolute minimum requirements to run Server 2012 R2：

Be aware that 32 GB should be considered an absolute minimum value for successful installation. This minimum should allow you to install Windows Server 2012 R2 in Server Core mode,with the Web Services (IIS) server role. A server in Server Core mode is about 4 GB smaller than the same server in Server with a GUI mode. For the smallest possible installation footprint,start with a Server Core installation and then completely remove any server roles or features you do not need by using Features on Demand. For more information about Server Core and Minimal Server Interface modes,see Windows Server Installation Options.
