Some info please.
SSD or HDD, what port is the drive on, what color, if black, are they the 0, or the A0, what have you set in the bios for sata, is the drive new or used ?
It doesn't matter if you are installing a single drive or a raid array, you don't need drivers, win 7 has them as default.
Do you actually get to the point screen that say's, where to install windows, but there is no disk listed ?
Go to bios, advanced, storage config, set Sata mode AHCI, Aggressive disabled, Asmedia disabled, Hard smart enabled.
