Well, I know this isn't the answer you want to hear, but you may need to get into BIOS (stands for Basic Input/Output System and is encoded into a chip on your motherboard). Once there you need to figure out which page has the drive information (though it may start up to that page - depending on the brand of BIOS). And you need to Enable LBA (Large Block Addressing) for that drive.
Oh, the most frequent way to enter BIOS is by hitting the "Delete" key a few times, right after you hear a beep on start up. However, this will be different if it's a Dell, or some such proprietary brand.
