Install Windows Server 2012 R2 - MCSA Windows Server 2012 R2: Installation and Configuration Study Guide - page 29

In step 1, imagepath is the path where the WIM files are located.
2. Run the following command:
Install-WindowsFeature featurename -Source wim: path:index
In step 2, featurename is the name of the role or feature from Get-WindowsFeature .
path is the path to the WIM mount point, and index is the index of the server image
from step 1.
To add or remove a role or feature, you must have administrative rights to the Windows
Server 2012 R2 machine.
Storage in Windows Server 2012 R2
As an IT administrator, you'll need to ask many questions before you start setting up a
server. What type of disks should be used? What type of RAID sets should be made? What
type of hardware platform should be purchased? These are all questions you must ask when
planning for storage in a Windows Server 2012 R2 server. In the following sections, I will
answer these questions so that you can make the best decisions for storage in your net-
work's environment.
Initializing Disks
To begin, I must first discuss how to add disk drives to a server. Once a disk drive has been
physically installed, it must be initialized by selecting the type of partition. Different types
of partition styles are used to initialize disks: Master Boot Record (MBR) and GUID Parti-
tion Table (GPT) .
MBR has a partition table that indicates where the partitions are located on the disk
drive, and with this particular partition style, only volumes up to 2TB (2,048GB) are
supported. An MBR drive can have up to four primary partitions or can have three
primary partitions and one extended partition that can be divided into unlimited logical
drives.
Windows Server 2012 R2 can only boot off an MBR disk unless it is based on the
Extensible Firmware Interface (EFI); then it can boot from GPT. An Itanium server is
an example of an EFI-based system. GPT is not constrained by the same limitations as
MBR. In fact, a GPT disk drive can support volumes of up to 18EB (18,874,368 million
terabytes) and 128 partitions. As a result, GPT is recommended for disks larger than
2TB or disks used on Itanium-based computers. Exercise 1.3 demonstrates the process of
initializing additional disk drives to an active computer running Windows Server 2012 R2.
If you're not adding a new drive, then stop after step 4. I am completing this exercise using
Computer Management, but you also can do this exercise using Server Manager.
