Windows 7 - The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks

When trying to install W7 in 64-bit form using an Intel DP45SG mainboard.  I get the error message "The selected disk has an MBR partition table.  On EFI systems, Windows can only be installed to GPT disks."

I have a new (SATA) hard drive that I am trying to install to.  I guess I need to do something to change the formatting/partitioning.  Where do I go from here?

I installed the W7 32-bit version and it works like a champ.

Try forcing the computer to boot the Windows 7 setup disc in BIOS mode, versus EFI mode. Just hit ESC when booting up to take you into the EFI boot manager and select the DVD-DRIVE, versus the ACPI(....) string.
