So I just installed Windows 7 onto my SSD, which I am using exclusively for my OS. When I first start up the pc, it goes straight to the ASUS Express Gate main menu then continues to initialize BIOS once i exit. Afterwards it trys to boot Windows 7 from the drive but doesnt recognize it right away and says Disk Information. Disk not found or something to that means for about 2 seconds, then continues to boot up windows 7 a couple seconds afterwards. I am pretty sure i my bios configuration is ok, but still a bit clueless due to my inexperience.

Also i have four monitors set up horizontally and was wondering if there was any way to span them in Win7. Along these lines, since i have 2 HD5850s what would be the best way to run four monitors in a (4x1) configuration with Eyefinity. I have it setup in extended mode right now with a 1 2 3 4 monitor configuration where the primary screen is 2.

Thanks and sorry in advance for any newbish like questions, just getting started.
