Each partition style has different capabilities and partitioning styles. Of most significance is the fact that the two partition styles have very different configurations in terms of special mandatory partitions required in order to store data. In addition, other mandatory partitions are required on each disk style in order to operate as boot and system disks. In terms of MBR disks a master boot record (MBR) partition is required. On GPT disks, EFI system (ESP) and Microsoft Reserved (MSR) partitions must be present in order for the disk to be bootable. It is important, therefore, that these partitions are created as part of the system disk mirroring configuration process.

The process of mirroring boot and system volumes on Windows Server 2008 MBR disks is considerably more straight forward than on GPT disks. For the purposes of this chapter we will be working with a system containing 2 disk drives. Disk 0 is the system disk and disk 1 is an unallocated disk installed for the purpose of mirroring the system disk. This process can be performed using either the Disk Management interface or from the command prompt using the '''diskpart''' tool (covered in the next section). The Disk Management interface can be accessed either from the Server Manager or Computer Management tools. To launch the Server Manager, open the Start menu and click on the Server Manager option, or click on the Server Manager icon in the task bar. Alternatively launch Computer Management from Start -> All Programs -> Administration Tools -> Computer Management or run compmgmt.csc at the command prompt or in a Run dialog.

Before the system disk can be mirrored it must first be converted to a dynamic disk. To achieve this right click on the system drive in the Disk Management graphical view, select ''Convert to Dynamic Disk...'' from the popup menu and follow the instructions in the resulting dialog to perform the conversion.
