Booting from a VHD
Once you have installed each operating system, you can choose the operating system that
you will boot to during the boot process. You will see a boot selection screen that asks you
to choose which operating system you want to boot.
The Boot Configuration Data (BCD) store contains boot information parameters that
were previously found in boot.ini in older versions of Windows. To edit the boot options
in the BCD store, use the bcdedit utility, which can be launched only from a command
prompt. To open a command prompt window, do the following:
1. Launch \Windows\system32\cmd.exe .
2. Open the Run command by pressing the Windows key plus the R key and then entering
cmd .
3. Ty p e cmd.exe in the Search Programs And Files box and press Enter.
After the command prompt window is open, type bcdedit to launch the bcdedit utility.
You can also type bcdedit /? to see all of the different bcdedit commands.
Virtualization is covered in greater detail in Chapter 9: “Use Virtualization
in Windows Server 2012.”
Summary
In this chapter, you studied the latest advantages of using Windows Server 2012 R2. You
also learned about the different roles and features you can install on a Windows Server
2012 R2 machine. You also explored how to migrate those roles and features from a Win-
dows Server 2008, 2008 R2, and Windows Server 2012 machine to a Windows Server
2012 R2 machine.
I discussed the different upgrade paths that are available and which upgrades are best
for your current network setup. You learned that another important issue to decide when
installing Windows Server 2012 R2 is whether to use Server Core or the GUI installation.
You learned how to install Windows Server 2012 R2 Datacenter with GUI, and you
installed the Windows Server 2012 R2 Server Core. Remember, Server Core is a slimmed-
down version of Windows Server. With no GUI desktop available, it's a safer alternative to
a normal Windows install. As discussed, a nice advantage of Windows Server 2012 R2 is
that you can change from Server Core to the GUI version and back again.
I discussed a feature called Features On Demand. This feature allows you to remove
roles and features from the operating system and remove the associated files completely
from the hard drive, thus saving disk space.
You examined the various aspects of Windows Server 2012 R2 storage services as well
as the various types of storage technologies and native Windows Server 2012 R2 storage
