You have a computer that runs Windows XP.

The computer has one basic disk that contains a single partition. The partition has 30 GB of free space. The hard disk has 5 GB of unallocated space.

You need to install Windows 7 in a dual-boot configuration.

Windows 7 must not be installed in a virtual hard disk (VHD).

What should you do first?

A.
Create a second partition.

B.
Shrink the primary partition.

C.
Convert the hard disk to a GPT disk.

D.
Convert the hard disk to a dynamic disk.

Explanation:
Given the system requirements more space is required.
There is not enough unallocated space so the XP partition will need to be shrunk first, in order for a sufficient sized partition to be created.

Requirements:
Windows 7 Home Premium, Professional, Ultimate, and Enterprise editions have the following minimum hardware requirements:

* 1 GHz 32-bit (x86) or 64-bit (x64) processor
* 1 GB of system memory
* a 40 GB hard disk drive (traditional or SSD) with at least 15 GB of available space
* a graphics adapter that supports DirectX 9 graphics, has a Windows Display Driver Model (WDDM) driver, Pixel Shader 2.0 hardware, and 32 bits per pixel and a minimum of 128 MB graphics memory
