This was the answer I got from gigabyte - it's a mobo issue:
Please use the attached driver and follow procedure below:
1) Extract driver to a folder on USB flash drive. Make sure SSD hard drive connect to SATA port 0, SATA DVD drive connect to SATA port 5 ( refer to mother board manual page 7 diagram to locate SATA ports ).
2) Reset bios to load fail-safe defaults and load optimized defaults, change on chip SATA type to AHCI mode under integrated peripherals in bios, change first boot device from floppy to CDrom, insert Win7 installation disk, save setup exit.
3) System will restart, when message show boot from CD/DVD press any key, at this point press enter key, Win7 setup screen will show.
4) When reach the point Win7 ask for install driver, browse to the folder on USB flash drive which has the extracted SATA driver install it, Win7 will recognize SATA drive and continue to complete installation.
Best regards,
