5. Type select disk [number] to select your flash drive.
6. Type clean to remove any formatting from the selected disk.
7. Type create partition primary.
8. Type select partition 1 to select the only partition now on the flash drive.
9. Type active to mark the partition as active.
10. Type format quick fs=fat32 to format the disk in FAT32 (otherwise the drive will not be bootable).

12. Type exit to exit Windows DiskPart utility.
