Hi You are right there is no sata drivers for your computer because you only have one hard drive go into the bios as shown here .and set AHCI to IDE   Integrated Peripherals Allows you to enable or disable these integrated devices: HD Audio, Onboard LAN connector, Onboard LAN Boot ROM, and Side logo. Serial ATA Configuration can be set to IDE or AHCI mode.  then install your version of windows you should not have any problems now  . Good Luck  
Hi, My Dell Studio Hybrid desktop is hang on installation (fresh installation on formated harddrive) of Vista at the completing installation stage.  After much research it seems it is a pre Vista SP1 issue related to SATA drive/drivers.  The installation hangs because the computer is looking for a driver on the CD-ROM which isn't there.  Anyway I don't see a relavent driver in the hybrid's driver section (other computer's have drivers under SATA drives) and if i did I wouldn't know at what point to add it (load driver section during installation process?).  Any help on this matter and how to complete the vista installation would be much appreciated since I've just lost my weekend to this.
