  • Boot from the DVD, you'll want to perform a custom install. Drive options (advanced) will give you the option to format your drive.

    See for below for a guide

    or the very poor Microsoft instructions

  • Rather than use the 'Format' command, it would be best to instead first DELETE the relevent partition, and then to CREATE a new partition of the same size, in the resulting free drive space.  A format will be performed as part of the install procedure, without the need to actually issue a 'Format' command.

    Format by itself can potentially leave residual problems in the drives MBR.  Delete/recreate partition doesn't have such potential problems.  (that's as I understand it all, anyways.)

    Regardless, the notion of 'formatting' a drive to clean it up is a notion which belongs back in the Windows 9x era!  Delete/recreate partition is a far preferable approach to take.  The relevent 'buttons' are found same place as the 'Format' button, during the Windows install routine.

    Cheers
