Choose a new designation for the drive by typing it in the Volume Label field, select the NTFS or FAT32 file system, and set the allocation unit size to the default value unless you want to customize it. Finally, select the Standard Format or Quick Format option, click OK to start the process, and wait until the Status message changes to Healthy.

For a primary hard drive, insert the Windows installation disc, and restart your computer. Press the appropriate key when the Select Boot Device or Change Boot Order option appears while the computer is booting up, and select the optical drive housing the installation disc as the primary boot device. Follow the instructions in the installation wizard, select the primary hard drive when prompted, and complete the installation process to format the drive.
