Overview
ZAP.COM will delete the existing MBR (Master Boot Record) from a Hard Disk
Drive. After this, any partitions on the HDD will no longer be recognized,
and the disk will be completely unusable.
You then need to use the "FDISK" utility for the desired operating system,
to create partitions on the HDD.
