Before attempting to install the operating system, you must create a virtual disk on your server to make available space accessible for the image download. The download erases the contents of the disk.
Virtual disks can be created from the LSI firmware for downloading the operating system. The LSI firmware can be reached only during boot-up of the server. Before Windows is launched and when the LSI banner is shown, you can press the Control-H key combination to access the LSI interface.
Note - Virtual disks can also be created from the MegaRAID software (which is installed through the supplemental drivers on the Tools and Drivers DVD), but should not be used for installing the operating system.
