Your network contains a server named Server1.
You start Server1 by using a Microsoft Windows Preinstallation Environment (Windows PE) image.
You copy a virtual hard disk (VHD) image named VHD1 to Server1. VHD1 contains a Windows Server 2008 R2 image.
You need to configure Server1 to start from VHD1.
Which tool should you use?
A. Bcdedit
B. Bootcfg
C. Diskpart
D. Dism
Correct Answer: A
Explanation/Reference:
To add a native-boot VHD to an existing Windows 7 boot menu
If you are deploying the VHD to a computer with an existing Windows 7 or Windows Server® 2008 R2 installation, you can use the BCDedit tool to make the new VHD bootable and add it to the boot menu. For more information about using the BCDedit tool, see this Microsoft Web site.
1. Copy an existing boot entry for a Windows 7 installation. You will then modify the copy for use as the VHD boot entry. At a command prompt, type:
bcdedit /copy {default} /d "vhd boot (locate)" When the BCDedit command completes successfully, it returns a {GUID} as output in the Command Prompt window.
2. Locate the {GUID} in the command-prompt output for the previous command. Copy the GUID, including the braces, to use in the following steps.
3. Set the device and osdevice options for the VHD boot entry. At a command prompt, type:
bcdedit /set {guid} device vhd=[locate]windows7.vhd bcdedit /set {guid} osdevice vhd=[locate]windows7.vhd
4. Set the boot entry for the VHD as the default boot entry. When the computer restarts, the boot menu will display all of the Windows installations on the computer and boot into the VHD after the operating- system selection countdown completes. At a command prompt, type:
bcdedit /default {guid}
5. Some x86-based systems require a boot configuration option for the kernel in order to detect certain hardware information and successfully native-boot from a VHD. At a command prompt, type: bcdedit /set {guid} detecthal on
