How to Repair an Invalid Dynamic Disk?

Since the popularity of Windows 7, I intend to install a Windows 7 operating system on my computer. Because I have installed an operating system of Windows XP on disk 1, so I intend to install Win7 on disk 2. However, after the installation, disk 2 becomes inaccessible. In Disk Management, it shows that "Disk 2 is INVALID" as you can see in the screenshot below. How can solve this problem?


Then I surf on the Internet, and now I know that the Win7 is a home edition, which is not supported by dynamic disk. Actually, all the Windows Home Editions can not work with dynamic disk, such as, XP, Vista, Win7 home. There are some methods to solve this problem, but the Disk Management can only delete the dynamic partition to convert it to basic, which will lead to a great data loss. Apart from this, there are two other ways.
