I had convert my OS disk to dynamic accidently, how do i convert back to basic disk? HELP!!

To change a dynamic disk back to a basic disk using the Windows interface: Back up or move all volumes on the disk you want to convert from dynamic to basic. For more information about backing up volumes, see Windows help. Open Computer Management (Local). In the console tree, click Disk Management. Where? Computer Management (Local) Storage Disk Management Right-click the dynamic disk you want to convert to a basic disk, and then click Delete Volume for each volume on the disk. When all volumes on the disk have been deleted, right-click the disk, and then click Convert To Basic Disk. Notes: To open Computer Management, click Start, point to Settings, and then click Control Panel. Double-click Administrative Tools, and then double-click Computer Management. You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure. If your computer is connected to a network, network policy settings may also prevent you from completing this procedure. The disk must be empty before you can change it back to a basic disk. If you want to keep your data, back it up or move it to another volume before you convert the disk to a basic disk. Once you change a dynamic disk back to a basic disk, you can create only partitions and logical drives on that disk.

PS. This WILL wipe your HDD, so you'll have to reinstall Xp...........
