To create and test a mirrored system or boot volume (32-bit only)
To ensure that your x86-based computer can load Windows if one of the disks or controllers fails, you can mirror the system volume. This makes an exact copy of the volume that contains the hardware-specific files needed to load Windows. You can also mirror the boot volume. This makes an exact copy of the volume that contains the Windows operating system.

To create a mirrored system or boot volume

Print this procedure or write down the steps before attempting to create a mirrored system or boot volume.
Read and understand all of the information in the Important and Notes sections.
Open Computer Management (Local).
In the console tree, click Disk Management.

If the system or boot volume already resides on a dynamic disk, skip to step 6. Otherwise, you must convert the disk to a dynamic disk before you can mirror it.
How?

Right-click the disk that contains the system or boot volume and click Convert to Dynamic Disk.
Caution

Do not convert basic disks to dynamic disks if they contain multiple operating systems (for example, the disk is set up to dual boot with another operating system). After the disk is converted to dynamic you can start the operating system that you used to convert the disk, but you will not be able to start the other operating system(s) on the disk.
In the Convert to Dynamic Disk dialog box, select the basic disk you want to convert to dynamic and then click OK.
In the Disks to Convert dialog box, click Convert.
In the Disk Management dialog, click Yes.
In the Convert Disk to Dynamic dialog box, click Yes.
In the Confirm dialog box, click OK to restart your computer.
After your computer restarts, log on. On the System Settings Change dialog box, click Yes to restart your computer again.
After your computer restarts, log on.
Open Computer Management (Local).
In the console tree, click Disk Management.

Continue to step 6.

Right-click the system or boot volume and click Add Mirror.
In the Add Mirror dialog box, select an unallocated dynamic disk with enough free space to mirror the system or boot volume and click Add Mirror.
Disk Management resynchronizes both disks. When resynchronization is complete, the system or boot volume is a fault-tolerant mirrored volume.
