  11. Click the Untitled 2 partition and in the Name text box enter VISTA, select MS-DOS (FAT) as the Format and enter 100.00 in the Size text box.

    Note: We will format the two Windows partitions as NTFS when we install Windows as we are not able to using Disk Utility. Also note that the labels will be overwritten, but entering them here helps to avoid mistakes later on. Also the final size of the 2K8 (3rd) partition will be slightly less after the partition and format is complete.
  12. Click the Untitled 3 partition and in the Name text box enter 2K8, select MS-DOS (FAT) as the Format and note that the remaining space (27.31GB) is automatically entered.
  13. Once you are happy with the partition sizes, click the Apply button and on the confirmation dialog, click Partition.
  14. Wait while the changes are applied, and then quit Disk Utility by pressing Command-Q. You will be returned to the Welcome page.
