This article may help explain the diffrence between basic and dynamic discs.

The Difference Between Basic and Dynamic Hard Disks - PC Hardware - Find Free Computer Help Tips Online

After a basic disk is converted to a dynamic disk, it cannot be converted back without losing your data. If you want to go back make sure to back up your files first. You must first delete all dynamic volumes on the disk and then convert the dynamic disk back to a basic disk.

According to this Microsoft Answers forum thread, if you convert the disk(s) to dynamic, you will not be able to start installed operating systems from any volume on the disk(s) (except the current boot volume).

Dynamic disks are not supported by this operating system or server - Microsoft Answers

Starting with Vista/Server 2008, the operating system's installation program doesn't allow the operating system to be installed on a dynamic disk. It's all related to security issues. This Microsoft KB article explains that if the hard disk on which you want to install Windows Vista, Windows 7 or Windows Server 2008 R2 is a dynamic disk, you will probably receive a "Windows is unable to find a system volume that meets its criteria for installation" error message. So it's safer to install your operating system on a basic disk. One of our own Forum members (gregrocker) who is also a microsoft MVP says the same thing.

You cannot select or format a hard disk partition when you try to install Windows Vista, Windows 7 or Windows Server 2008 R2

can I install windows 7 on a dynamic disk?

Here's how to convert from dynamic to basic disk.

Convert a Dynamic Disk to a Basic Disk

As far as I know, you must backup and save any data on the drive before converting it. It's not possible to leave "dynamic data" on a drive that's been converted back to basic because all dynamic partitions/volumes will be deleted. Depending on how much data you have (and from your disk management screenshot it looks like you've got about 450GB) you might want to invest in an external hard drive. From the above tutorial:

warning   Warning
Before you convert a dynamic disk to a basic disk, be sure to backup anything that you do not want to lose on that dynamic disk. Converting the dynamic disk back to a basic disk requires that all dynamic volumes are deleted on the disk first.
