Portlock Leap Frog will assist you in creating a bootable Virtual Hard Disk (VHD) for native Windows deployment with your Windows XP, Windows Vista, Windows 7, Windows Server 2003, Windows Server 2008 or Mac OS X Snow Leopard machine. The VHD can be used as the running operating system on supported hardware without a virtual machine or hypervisor. This provides an excellent way for end users who wish to utilize the VHD technology and setup a multi-boot environment with Windows XP and Windows Vista without having to "Upgrade" or repartition the hard disk.
Portlock Leap Frog has been developed and designed to provide end users the ability to utilize the new VHD-boot capabilities in Windows 7 and Windows Server 2008 in one easy to use wizard. Portlock Leap Frog eliminates steps for VHD-boot setup such as the need to first boot the system to the Windows install DVD as well as the use of tools such as the "Disk Management" console and command prompt tools such as "Diskpart" and "BCDedit."
