DISKPART may be used to enable storage configuration or create a partition at an explicit
disk offset from a script, a remote session, or another command prompt.
Dell recommends using WinPE's (3.0 or greater) Diskpart.exe from Windows Vista or
Windows 7 to create the partitions for Windows XP installation. This will create a partition
that is Advanced Format aligned. Without PE, starting with Windows Vista or Windows 7 DVD
to create the partition for the Windows XP will create correct partitioning. On how to use
DISKPART utility and how to divide the offset value of the selected partition, refer to
Microsoft KB Article 300415
