As Greg stated, there is no reason I know of for you to be in raid mode in bios. Before you install, follow gregs tutorial Clean Reinstall - Factory OEM Windows 7 but also, before the install, make sure your sata controller is not set to raid mode. Set it to AHCI. If you have trouble installing in AHCI, which you shouldn't, put it in IDE mode. Raid mode is totally unnecessary and only useful if you are running a raid array.
