Disconnect HDD - connect SSD
Set Bios to ahci and Install windows 7
IF your is an Intel chipset (ie H/P5x, or X58, or uses the ICH7 or later southbridge AND your SSD uses the SF12xx controller. Download the latest Intel RST driver, also the "F6" driver (Ver 9.6 or later). Do a custom instal. On the page that ask where to instal, check the check box for "Have driver". When asked broose to the Thumb drive that you put the F6 driver on.
Disregard Note if on AMD platform) - do a normal installation and use the default mssoft ahci driver.
