Preparing Windows Server 2003 for iSCSI boot
These instructions assume that you have an installation of Windows Server 2003 on a local hard disk. We will make this installation iSCSI-boot-capable, then copy it to a remote iSCSI target and boot from it.
You will need to install the Microsoft iSCSI Software Initiator Boot Version. You must obtain this from http://connect.microsoft.com by signing up with the invitation code ms-8RR8-6K43. This is not the standard Microsoft iSCSI Initiator; you do need the special boot-capable version.
Reboot after installing, and check that the system comes up correctly. You can now proceed to Transferring the operating system image to an iSCSI target.
